This PACCAR multiplexed electrical manual is the full Electrical System Service Manual, publication PM819003/KM815056, dated 09/16/2011, covering trucks equipped with the “CECU3 with Chassis Node” multiplexed instrumentation platform. It was published by PACCAR Corporation for use with the Electronic Service Analyst (ESA) diagnostic software and spans safety notes, general information, wiring, and a full gauge-by-gauge DTC troubleshooting index. Because this PACCAR multiplexed electrical manual is the parent document behind dozens of individual DTC bulletins, it is the reference to open first when a fault code does not match a single-code sheet.

Applies to
This PACCAR multiplexed electrical manual applies to Kenworth and Peterbilt vehicles built with software version “CECU3 with Chassis Node” (P30-1009); trucks running prior CECU software versions such as ICU (P30-1003), CECU/CECU2 (P30-1002), or CECU3 (P30-1008) are covered instead by a separate publication, PM819010/KM815054, referenced in this manual’s safety section. Replacing the control unit resets the odometer, so the manual instructs technicians to record vehicle mileage first. See the PACCAR official site for current model lineups.
Who needs this PACCAR multiplexed electrical manual
Any technician diagnosing an inoperative gauge, a chassis node replacement, or a databused Engine Control Module fault on a 2011-and-newer Kenworth or Peterbilt needs this PACCAR multiplexed electrical manual as the master index into the individual DTC troubleshooting trees, ESA diagnostic setup notes, and CECU/Chassis Node pinouts.
The full PDF, including the full 197-page troubleshooting index is available in the DiagTechPro manuals library; a free account is required to download.
