The Electronic Service Analyst ( Paccar ESA ) is a PC-based diagnostic tool similar to CAT ET or Cummins INSITE. ESA communicates over a Data Link Adapter to the NAMUX components. A technician can use Paccar ESA to detect fault codes in the components, verify and troubleshoot new electronic instrumentation functionality, flash the control unit, program parameters and diagnose the root cause of the problems.


Paccar Electronic Service Analyst 5.5 is an improved diagnostic tool that is utilized for auto electronics and diagnostics. This is an interface driver for the PC based logic devices, such as diagnostic engine monitors, diagnostic trouble code monitors, idle sensors, fan control and idle limit sensors. Adapter supplies data exchange between PC and diagnostic logic device. Universal electronic service analysis is commonly applied to a wide array of different applications and functions and runs on PC alone.

With a program such as Paccar ESA, you can easily diagnose and troubleshoot your diagnostic issues. The software provides full online installation service for new electronic instrumentation tools. This service makes the new instrumentation completely ready to use without any compatibility issues with the original computer programs.
