Diagnostic Trouble Code Definitions

NOTE: Decimal test numbers for trouble codes were derived from hexidecimal codes as set in the PCM. Some test numbers will be missing because all codes are not applicable to vehicles covered in this manual.

(1) Not every Chrysler test has an associated P code.
(2) For an Engine Is Cold Too Long" trouble code, the engine does not warm to 176°F while driving for 20 minutes after start. Check thermostat. For an "Internal Controller Failure" trouble code, replace PCM and go to VER-2A: ROAD TEST VERIFICATION  . For a "PCM Failure SPI Communications" trouble code, replace the PCM and go to VER-2A: ROAD TEST VERIFICATION  .
