Paccar Electronic Service Analyst is the OEM diagnostic software for Kenworth and Peterbilt trucks. It provides data exchange between a PC and the vehicle control units via the diagnostic interface Nexiq Diagnostic Link v1 or v2. This version of paccar esa includes major bug fixes, performance improvements, and support for additional engine and aftertreatment modules.

Using a simple, intuitive user interface, this tool helps reduce the time technicians spend navigating complex systems and searching for information. It allows them to quickly understand fault codes, review live vehicle data and perform bi-directional tests, so they can increase the number of vehicles they can work on in a day.

The tool can also diagnose problems that traditional diagnostic tools wouldn’t find, such as those that don’t trigger a fault code. It can also identify problem areas and walk them through the best fix, whether that’s through fault-based or symptom-based troubleshooting. This saves time and money by reducing the amount of manual labor needed to repair a vehicle.

BELLEVUE, Wash. — Paccar Incorporated is recalling almost half a million Peterbilt and Kenworth tractor trucks to replace a faulty anti-lock brake (ABS)/electronic stability control (ESC) warning light that could fail. The problem is that the truck’s cab control module (CECU) could stop sending power to the ABS/ESC system, causing the warning lights to stay on.

The recall covers tractors with model years between 2007 and 2022 equipped with Paccar MX11 or MX13 engines, a Paccar Body Controller, and the Paccar NAMUX II chassis computer. The recalled trucks may have a defective electrical connection between the CECU and the chassis computer, which can cause the warning lights to remain on even after the truck is turned off.
