2023 Paccar ESA Electronic Service Analyst 5.6/5.4 with SW Files 2023


SKU: N/A Category: Tag:


Paccar Electronic Service Analyst (ESA) is a PC-based diagnostic tool similar to CAT ET or Cummings INSITE. ESA communicates over a Data Link Adapter to the NAMUX components. A technician can use 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 using service information on DealerNet.

Known Issues:

  • Restoring parameters to an ICU using an ECAT file with a Q21-1029 part number causes ESA to crash
  • Replacing an ICU with a CECU3 and downloading an ECAT file with a Q21-1029 part number will not limit the flashing options to P30-1030 as it should
  • JPRO DLA+ 2.0 and DLA+Wireless 2.0 will not detect PACCAR Display 1.0 on 2016 vehicles without the use of a crossover cable; not a significant concern since 2016 vehicles should not have PACCAR Display 1.0 devices installed
