PACCAR MX P060A is the fault-code chapter of the 2013 PACCAR MX Diagnostic Service Manual covering a fault on the engine controller CPU watchdog, in other words an internal controller fault rather than a sensor circuit. The page is a single-sheet entry with no published diagnostic tree, which is consistent with an internal ECU fault. Every field beneath the description, from diagnostic condition to verification drive cycle, is answered by one line: contact the Engine Support Center.

What the PACCAR MX P060A chapter covers
- The exact wording of the watchdog fault, for matching against a DAVIE readout
- Its classification as a controller fault rather than a wiring or sensor fault
- Confirmation that no set or reset condition is published
- Confirmation that no electrical diagram or technical data table appears
- Confirmation that no possible-cause list or numbered procedure exists
- The single published action: contact the Engine Support Center
Diagnostic step sequence and verification
Inside PACCAR MX P060A the procedure runs as follows. No sequence is printed, and for a watchdog fault that is appropriate. The other chapters in this manual repeatedly end their trees at possible PCI failure and route the decision to PACCAR before any controller is replaced, so this entry simply starts where those chapters finish. Confirm supply power and ground to the PCI are healthy, record the freeze frame, and open a support case.
Trucks and engines it applies to
The entry belongs to the EPA 2013 PACCAR MX code set in Kenworth and Peterbilt trucks, and relates to the PCI engine controller rather than to any single component on the engine. Model programmes and dealer support for these engines are listed on the PACCAR corporate site.
Who needs the PACCAR MX P060A chapter
Technicians who see this alongside a scatter of unrelated codes need this page, because a controller watchdog fault explains the scatter and stops a chain of unnecessary sensor replacements.
