SERVICE INFORMATION

Beginning in 2005, some control modules have specific codes that describe internal failures of the module. These DTCs are not module specific and can be found on any controller that has these codes.

Society of Automotive Engineers (SAE) J2012 committee has set these specific codes to be an industry standard of all manufacturers.

Currently, these common codes include:

P0601 - May be set in ECM, FPCM, PIM, TCM, TCCM
P0602 - May be set in ECM, FPCM, PIM, TCM, TCCM
P0603 - May be set in ECM, FPCM, PIM, TCM
P0604 - May be set in ECM, FPCM, PIM, TCM, TCCM
P0606 - May be set in ECM, FPCM, PIM, TCM, TCCM
P062F - May be set in ECM, FPCM, PIM, TCM, TCCM
P1621 - May be set in ECM, TCM
P16F3 - May be set in ECM, PIM, TCM

IMPORTANT:

Use caution when diagnosing these shared codes to perform the appropriate diagnostic procedure on the appropriate module. Be sure to check and understand which module has set the DTC before proceeding with diagnosis.
Do not replace any module before understanding which module has set the DTC, before following proper eSI diagnostics and until eSI diagnostics instruct to replace the module.

Refer to the appropriate Electronic Service Information (eSI) document for Diagnosis and Repair procedures.
