Frequently Asked Questions

What does Bosch ESI[Truck] cover?

ESI[Truck] is a multi-OEM heavy-duty platform covering Class 6–8 tractors and trailers across Cummins, Detroit, PACCAR, Volvo/Mack, International, and CAT, with bidirectional controls and forced regens on most current platforms. The optional OHW upgrade extends coverage to off-highway and construction equipment.

Is Bosch ESI[Truck] a single-vendor solution?

No — Bosch ESI[Truck] is a multi-make platform. Pair it with one OEM stack for the engine family you see most (INSITE for Cummins-heavy fleets, DDDL for Detroit, etc.) and ESI[Truck] handles the rest.

How does ADS 625 compare to ESI[Truck]?

ADS 625 is an Android tablet running Bosch software in a more portable form factor — ideal for mobile diagnostics or quick yard pulls. ESI[Truck] Professional runs on a Windows laptop and offers deeper functional testing for shop bays.

Does Bosch include training and support?

Yes — Bosch has a global service infrastructure with training, technical support, and parts. Subscription updates keep coverage current as OEMs release new model years.
