Repair Information
For OBD15 chassis:
- Software improvements have been released to address this code. If P2002 is
present and there are no other symptoms to indicate a physical issue, software
should be checked and updated as necessary.
- Two modules are affected by this update and should be reprogrammed in the
following order:
1. Engine Control Module ( EMS )
2. Aftertreatment Control Module ( ACM )
- If the code returns following the software update, normal diagnostic
procedures will need to be followed.
- Other codes present that are potentially related to P249C should be
diagnosed first.
For OBD16 chassis:
Ensure that Engine Management System ( EMS ) software is current.
If the code does not have a high count of occurrences and there are no other
symptoms or related codes present, clear the code and release the chassis
