Code Tech Notes
A dealer may encounter a customer complaint of a check engine light (SES light ON) and a P2610 DTC may be stored in the ECM. This DTC may set intermittently after a reflash of certain modules such as the transmission control module (TCM), or glow plug control module (GPCM). Additionally, any loss of battery voltage to the ECM while the ignition is ON, can also cause a P2610 to set.
Recommendation/Instructions:
If a P2610 has been verified do not replace the ECM. Perform the following steps when encountering a P2610.
Turn the IGNITION OFF for 90 seconds. Unplug both the Engine Control Module (ECM) connectors for 90 seconds. After 90 seconds has passed, re-install the ECM connectors. With the ignition on use the Tech2 and clear all codes in the ECM. This procedure should prevent future sets of the P2610. For 2006 and certain 2007 model vehicles, there may also be a calibration update available which addresses P2610 false sets.
