Shop Bendix Diagnostic Tools

If you turn wrenches on Class 8 trucks, Bendix is on your bench whether you ordered it there or not. Bendix Commercial Vehicle Systems builds the air brakes, ABS modulators, stability controllers, radar, cameras, and telematics that sit on roughly half the tractors and a huge slice of the trailers rolling through North America. The other half is WABCO/ZF. That is the entire market for heavy-duty brake electronics on this continent — two suppliers, and Bendix is one of them.

That matters because every ABS warning lamp, every ESP fault, every Wingman Fusion radar that goes blind after a windshield change, and every trailer that drops out of the tractor's TABS broadcast eventually lands in front of a tech with a laptop and an RP1210 adapter. If your laptop is not running Bendix's diagnostic software, you are guessing. Aftermarket scanners read codes. They do not perform the calibrations, the parameter writes, the dynamic radar alignments, or the sensor-learn procedures the OEM software performs. Brake work is where shops earn warranty hours back, and brake work on a modern tractor is electronic work.

This page lays out what Bendix actually makes, what runs on what chassis, what the current and legacy diagnostic software does, what aftermarket tools cover and where they stop, and what a working shop should keep on the cart. If you want to skip the reading and just talk through what fits your bays, call 866-217-0063. About nine of every ten orders we ship close on the phone, because matching software, adapters, and license terms to the work in your shop is faster as a conversation than as a checkout flow.

1. Who Bendix Is

Bendix Commercial Vehicle Systems LLC is headquartered in Avon, Ohio, with major operations in Elyria. The company is owned by Knorr-Bremse, the German braking conglomerate that also dominates rail brake systems worldwide. Knorr-Bremse bought into Bendix in the late 1980s and took full ownership of the commercial vehicle business in 2002. Since then, Bendix has been the North American arm of a global braking giant.

What Bendix sells in this market is the entire brake stack and most of what bolts onto it. Foundation brakes — air disc and drum — come out of Bendix Spicer Foundation Brake, a long-running joint venture. ABS controllers, traction control, stability control, automatic emergency braking, lane departure, and adaptive cruise all carry Bendix part numbers. Wingman Fusion, the camera-and-radar collision mitigation suite, is a Bendix product. SafetyDirect, the telematics back-end that captures ADAS events and feeds fleet portals, is Bendix. SmarTire tire pressure monitoring is Bendix. Intellipark electronic parking brake is Bendix. The list keeps going.

For a shop, the practical takeaway is that Bendix is rarely just one component. When a Wingman Fusion event throws a code, it is usually pulling data from the EC-80 ABS controller, the FLR-21 radar, the FLC-20 camera, and the engine and transmission ECUs over J1939. Diagnostics rarely stay inside one box. That is why OEM-level coverage matters.

2. What Bendix Makes

Here is the short tour of what you are likely to be looking at on a chassis:

ABS controllers. The current tractor ABS family is the EC-80, which superseded the older EC-60. EC-80 comes in Standard, Premium, and Advanced configurations. Standard is base ABS plus ATC. Premium adds stability control logic and additional inputs. Advanced supports full ESP with yaw-rate and steer-angle sensing and is the platform for stability-equipped tractors and Wingman Fusion. The EC-80 lives behind the bunk or under the cab depending on the OEM. Earlier units used the ABS-6 / Gen 5 architecture before EC-80 took over.

Trailer ABS. Bendix TABS-6 is the trailer module family. It handles 4S/2M, 2S/1M, and other configurations, talks PLC over the trailer cord, and stores blink-code-readable faults at the dash light. TABS-6 has its own diagnostic path, and proper trailer ABS work means dropping a laptop and a Bendix or Jaltest connector at the nose box, not just bouncing the seven-way.

Stability and ATC. Bendix ESP (Electronic Stability Program) is the full-stability product — yaw, lateral acceleration, steer angle, integrated with the ABS controller. RSP (Roll Stability Program) is a roll-only subset on older platforms. Both arbitrate brake and engine torque interventions through the EC-80 and over J1939 to the engine.

Wingman Fusion. Bendix's collision mitigation system, integrating the FLR-21 radar mounted in or behind the bumper and the FLC-20 camera mounted at the top of the windshield. Fusion does forward collision warning, automatic emergency braking, adaptive cruise, lane departure warning, and stationary-object alerting. It reports to SafetyDirect, the fleet telematics back-end.

AutoVue. The lane departure warning camera platform, also branded as Wingman Fusion's vision side. The FLC-20 is the current camera generation.

SafetyDirect. Cellular telematics that records hard-braking events, ADAS interventions, and driver behavior, then ships it to a fleet portal. When a fleet asks why their Fusion events are not showing up online, SafetyDirect is where you start.

SmarTire, Intellipark, GSBC, GSAT, iSense. Tire pressure monitoring, electronic parking brake, the global scalable brake control architecture (Bendix's next platform that is rolling out across new chassis), global scalable air treatment (the air dryer/governor/purge controller side), and the brake pad wear sensing system. All of these talk to the same diagnostic ecosystem.

3. Where You'll See Bendix

Pretty much everywhere. Daimler (Freightliner, Western Star), PACCAR (Kenworth, Peterbilt), Volvo, Mack, and International all spec Bendix on a meaningful chunk of their builds. The other chunk goes to WABCO/ZF. Most fleets do not specify brake supplier at order time — they take whatever the OEM is shipping that month, which means the exact same fleet number can have a Bendix tractor pulling a WABCO trailer pulling a Bendix dolly, and the tech in the bay needs both stacks on the laptop.

Some general patterns: Freightliner Cascadias have leaned heavily Bendix for ESC and Wingman Fusion. Kenworth and Peterbilt have a long Bendix history through PACCAR. Volvo and Mack have used both Bendix and WABCO over the years and the current builds typically run WABCO/ZF, but the legacy units in the yard are mixed. International runs both depending on year and model. Western Star and Volvo VNL Wingman-equipped units are common Bendix work.

For trailers, every major trailer OEM — Wabash, Great Dane, Utility, Stoughton, Hyundai Translead — ships Bendix TABS-6 and WABCO units in roughly equal proportions, again driven by what the chassis supplier had on the shelf. A shop that does any trailer work needs both.

4. ACom Pro and ACom AE Software

This is where you have to pay attention, because Bendix moved the goalposts in 2024 and a lot of shops have not caught up.

The history. The original Bendix ACom shipped in 2004. ACom Pro replaced it in 2019 and ran for five years as the standard Bendix diagnostic application. As of September 1, 2024, Bendix stopped selling ACom Pro licenses and rolled out the replacement: Bendix ACom AE, built in partnership with Cojali (the Spanish company behind Jaltest). ACom Pro support ended August 31, 2025 or when each existing license expired, whichever came first. If your shop is still running ACom Pro on an active license, it is a sunsetting product.

What ACom AE is. ACom AE is the current generation. It is modeled on the Jaltest platform but skinned and scoped for Bendix systems. It covers Bendix ABS, ESP, Wingman Fusion, SmarTire, Intellipark, GSBC, GSAT, iSense, BlindSpotter, and AutoVue — past, present, and future ECUs. Legacy ACom Pro coverage is embedded inside AE so you can still service older Bendix-equipped chassis without keeping two laptops.

License model. ACom AE is sold as a yearly subscription, $459 per license per year at MSRP, with software updates included — typically three releases per year at no extra charge. Languages: English, French, Spanish, switchable in the application.

What it does. Read and clear codes across all Bendix ECUs. Live data and parameter views. ECU configuration writes, including chassis-specific parameter sets when replacing a controller. Bleed sequences. Wheel speed sensor learn / initialize and calibrate. Yaw and steer-angle sensor calibration after suspension or alignment work. Dynamic and static radar alignment for Wingman Fusion. AutoVue camera commissioning after windshield replacement. SmarTire sensor learn. Intellipark setup. SafetyDirect linkage diagnostics.

OS and platform. ACom AE runs on current Windows 10 and Windows 11. It is more demanding than legacy ACom Pro on disk space and OS version — old XP and Windows 7 Toughbooks that limped along on legacy ACom will not run AE. If you are buying a Toughbook for this work, plan on a CF-33 or newer with Windows 11 and 16 GB of RAM. The application is a heavier install than Pro was.

What we sell. A new Bendix diagnostic license through Heavy Duty Truck Diagnostics gets you ACom AE current generation with embedded legacy coverage, the activation, and the matching adapter pairing. We will also sell you a complete diagnostic kit — software, RP1210 adapter, cables, and a configured Toughbook — if you want it on the cart and ready to go.

5. Adapters and Hardware

ACom AE talks to the chassis over an RP1210-compliant J1939 / J1708 adapter. It is not picky about brand — it follows the RP1210 standard and any current adapter that meets RP1210C will work. The common shop-grade options:

• Nexiq USB-Link 3. The fleet standard. Wired and Bluetooth versions. Pairs cleanly with ACom AE, ACom Pro, Jaltest, JPRO, Cummins INSITE, Detroit DDDL, and basically every other RP1210 application. If you are buying one adapter for the whole shop, this is the default answer.
• Noregon DLA+ 3.0. Noregon's RP1210 adapter, ships with JPRO and works fine with ACom AE. Common in shops that already standardized on JPRO.
• Cojali Jaltest adapter. Since ACom AE is built on Jaltest's platform, the Jaltest adapter is a natural pairing if your shop is already running Jaltest.
• Bendix RDU (Remote Diagnostic Unit). Older Bendix-specific tool used primarily on legacy ABS systems. Still useful for some pre-EC-80 work but not the main path for modern diagnostics.

For trailers, you need an adapter and a trailer-cord-to-9-pin or 7-way-to-9-pin pigtail to talk to TABS-6. Most shops keep a dedicated trailer harness on the cart so they are not pulling apart the tractor connection every time a trailer rolls in.

Cabling matters more than people expect. A questionable J1939 cable will throw intermittent comm-loss errors mid-procedure and waste an hour. Use the cable that came with the adapter, keep it coiled, replace it when it gets crushed.

6. What You Can and Can't Do With Aftermarket Tools

This is the question we field every day. Jaltest, JPRO, and TEXA all advertise Bendix coverage. The honest answer is that they cover most of the day-to-day work and stop short of a few specific procedures.

Aftermarket tools will read and clear Bendix codes across ABS, ESP, ATC, and stability. They will show live data on wheel speed sensors, yaw, lateral accel, and steer angle. They will run the bleed sequences. They will perform initialize and calibrate on wheel speed sensors. They will read trailer ABS faults through TABS-6 with the right harness. For the bulk of brake-light-on, sensor-replacement, ATC-not-working work, an aftermarket tool will get you home.

Where they get thin is on the safety/ADAS side and on certain parameter-set writes. Wingman Fusion radar dynamic alignment, AutoVue camera commissioning after windshield replacement, full Wingman parameter writes, SafetyDirect telematics linkage, Intellipark commissioning on the newer architectures, and some EC-80 chassis-specific parameter writes are areas where ACom AE either does the procedure cleaner or is the only path. Cojali's Jaltest sits closest to ACom AE on coverage because it is the same underlying platform — in practice, modern Jaltest will do most of what AE does, but the OEM tool still wins on edge cases and on first-day-of-release support for new ECUs.

If your shop calibrates radars and cameras after windshield work or accident repair, you need ACom AE. Full stop. If you do brake-only work and never touch ADAS, you can probably get by on Jaltest or JPRO with occasional fall-back help. Most shops that try to live on aftermarket-only end up buying ACom AE inside the first year because one Wingman Fusion event chases them into it.

Bendix ACom AE vs. Aftermarket Coverage Matrix

Procedure	ACom AE	Jaltest	JPRO	TEXA
Read / clear ABS, ESP, ATC codes	Full	Full	Full	Full
Wheel speed sensor live data	Full	Full	Full	Full
Initialize and calibrate (wheel sensors)	Full	Full	Most	Most
Yaw / steer angle / lateral accel calibration	Full	Most	Limited	Limited
EC-80 parameter writes / chassis configuration	Full	Most	Limited	Limited
Trailer ABS (TABS-6) full diagnostics	Full	Full	Full	Most
Wingman Fusion FLR-21 dynamic radar alignment	Full	Limited	Read-only	Read-only
AutoVue FLC-20 camera commissioning	Full	Limited	Read-only	Read-only
SafetyDirect telematics linkage	Full	Read-only	Read-only	Read-only
SmarTire sensor learn / TPMS	Full	Most	Limited	Limited
Intellipark commissioning	Full	Limited	Limited	Limited
Day-one support for new Bendix ECUs	Full	~3-6 month lag	Lag	Lag

"Full" means the procedure runs through to completion without workarounds. "Most" means the typical case works, edge cases need the OEM tool. "Limited" means it works on older platforms but is unreliable or absent on current ECUs. "Read-only" means you can see the data but cannot perform the calibration.

7. Common Service Pain Points

The Bendix calls we field at the shop level cluster around the same handful of problems:

ABS lamp on with wheel speed sensor codes (SPN 815, 1067, 800). Almost always either a contaminated tone ring, a sensor pushed back from the ring, a corroded sensor pigtail, or a chewed harness. Pull the sensor, clean the bore, set the tone ring gap (touch the ring then back off until the sensor is just shy of dragging), check the air gap with the wheel turned, then run Initialize and Calibrate in ACom AE to clear the learned offsets. About 80% of "ABS won't go off" calls end here.

ESP codes after a steer axle alignment. The steer angle sensor remembers its zero point and a four-wheel alignment moves the wheel relative to the sensor. You have to recalibrate steer angle through ACom AE after any steering work, and you have to do it on a level surface with the wheels truly straight. Skipping this calibration is the leading cause of "ESP randomly comes on" complaints after an alignment.

Wingman Fusion radar / camera faults after a windshield replacement. The FLC-20 camera lives on a bracket bonded to the windshield. Pull the windshield, you pull the camera mount. The replacement windshield needs the correct bracket for the chassis, the camera reinstalled to the OEM measurement, and a full camera commissioning routine in ACom AE. This is also a frequent occasion for radar alignment, since the FLR-21 mounting can shift if the bumper was off for any reason. Lateral target -1.5° to +1.5°, vertical 0° ±1.5°, digital inclinometer, and dynamic alignment on a flat highway with a lead vehicle 50-300 feet ahead at 35+ mph if the static won't seat.

Trailer ABS warning lamp. The trailer light at the dash is fed over PLC through the seven-way. Most trailer ABS warnings are corroded seven-way connectors, broken sensor harnesses, or a TABS-6 module with a power supply issue. Read the codes through ACom AE or Jaltest with a trailer harness. Do not chase ghost faults by swapping modules.

SafetyDirect events not appearing in the fleet portal. SafetyDirect needs cellular signal and a current subscription. Check the antenna, check the cellular modem status in ACom AE, verify the subscription with the fleet, and confirm the truck has actually had an event worth uploading. About half these calls turn out to be "the fleet account expired."

Air system faults that look electrical. The current generation of Bendix air management runs through the GSAT controller. Air dryer purge timing, governor cut-in / cut-out, and unloader function are all electronically managed on newer trucks. If you are chasing a slow build or a constant cycling complaint and the mechanical side checks out, the diagnostic is in software now.

8. What Your Shop Needs

The kit answer depends on what you actually do. Three common shapes:

Brake-and-trailer shop, no ADAS work. ACom AE on a current Toughbook (CF-33 or newer with Windows 11), Nexiq USB-Link 3, a tractor 9-pin cable, a trailer ABS harness, and Jaltest as the all-makes back-up for the engine, transmission, and other ECUs you will inevitably trip over. This is the working setup for most independent diesel shops.

Brake shop that does ADAS and collision repair. Same kit as above, plus a digital inclinometer rated for radar work, a printed copy of the OEM camera mounting measurements for the chassis you see most (Cascadia, Volvo VNL, Kenworth T680), and bay space to do a static alignment with a target board if you can swing it. Expect to do dynamic alignments on the road for a portion of jobs — that is normal, not a kit failure.

Fleet maintenance shop, all-makes. ACom AE plus WABCO TOOLBOX PLUS for the brake/ESC duopoly. JPRO or Jaltest for everything else. A pair of Toughbooks because you do not want one laptop bottleneck blocking three open work orders. Adapter on each laptop. Subscriptions tracked centrally so they do not expire mid-job.

If you want help building this out, the phone is the fastest path. We will talk through what you have, what you are missing, and what you can skip. About nine of every ten orders close on the call, and we would rather get the kit right than ship you a license that won't run on the laptop you have. 866-217-0063.

FAQ

Will Jaltest do a Wingman Fusion radar alignment?
Static parameter reads, yes. Full dynamic radar alignment with the FLR-21 calibration write-back, no — that is an ACom AE procedure. Since ACom AE is built on the Jaltest platform, Jaltest is the closest aftermarket tool to AE, but the OEM application is still the right path for radar and camera commissioning.

Do I need ACom AE just for ABS work?
For straight code-read, code-clear, and most sensor-replacement work, no — Jaltest, JPRO, or TEXA will get you home. For chassis-specific parameter writes when replacing an EC-80, for full ESP calibrations, and for any work on a Wingman-Fusion-equipped truck, yes — you want ACom AE.

What's the difference between ACom and ACom Pro and ACom AE?
ACom shipped in 2004 and is long retired. ACom Pro replaced it in 2019 and stopped being sold September 1, 2024, with support ending August 31, 2025. ACom AE is the current product, built on Cojali's Jaltest platform, covering all current and legacy Bendix ECUs in a single application. If you are buying new today, you are buying ACom AE.

Does ACom AE cover trailer ABS?
Yes. ACom AE reads, clears, and configures Bendix TABS-6 trailer ABS modules. You need a trailer-side harness to talk to the trailer through the seven-way, but the software covers it.

Will it run on a Toughbook?
Yes, on a current Toughbook running Windows 10 or Windows 11. Older CF-19 / CF-30 / CF-31 units running Windows 7 or XP will not run ACom AE — the platform requirements moved up. CF-33, CF-54, and newer units with 16 GB of RAM are the comfortable target.

Can I use my Nexiq USB-Link 3 with ACom AE?
Yes. ACom AE follows the RP1210C standard and works with any current RP1210 adapter, including Nexiq USB-Link 3, Noregon DLA+ 3.0, and the Cojali / Jaltest adapter. You may need to install the adapter's RP1210 driver and select it inside the ACom AE connection setup the first time.

What if I still have a valid ACom Pro license?
Bendix support for ACom Pro ended August 31, 2025. The application may still launch and run on systems where it is installed, but you will not get updates and you will not get support. If you are doing this work for revenue, move to ACom AE.

Why Buy Bendix Tools and Software From Heavy Duty Truck Diagnostics?

Three reasons. First, we sell the right thing the first time. We are not going to sell you ACom Pro in 2026 because Bendix already pulled it. We will sell you ACom AE, with the matching adapter, and we will tell you on the phone whether your laptop will run it before you swipe a card.

Second, we know what overlaps. If you already own Jaltest, we will tell you what AE adds and what it duplicates. If you already own JPRO, we will tell you where it falls short on Bendix ADAS work. We are not running a one-tool catalog — we sell Bendix, WABCO, Jaltest, JPRO, TEXA, OEM tools across all the major chassis, and we cross-reference them in the conversation. Most shops end up with two or three platforms, not one, and the right combination depends on what you actually fix.

Third, we ship working kits. The Bendix Complete Fleet Diagnostic Kit at $3,495 ships with software, adapter, and cabling configured to talk to a truck out of the box. The standalone Bendix diagnostic software license at $1,895 ships with activation support — we will get on the phone with you while you install it. The adapter bundle at $695 fills the gap if you already own software but need cabling. None of this is one-click checkout. It is a phone call, a kit that matches your shop, and a tech on the other end who has put hands on the same trucks you have.

Roughly 90% of the orders we ship close on the phone. That is not a sales pitch — it is the way this category actually works. Diagnostic software has subscription terms, OS dependencies, adapter pairings, and brand overlaps that do not fit on a product page. Call us, tell us what you are working on, and we will build the kit.
