SUBJECT:
Flash: MIL Illumination For P2610 - PCM Internal Engine Off Timer Performance
OVERVIEW:
This bulletin involves flash reprogramming the Powertrain Control Module (PCM) with new software.
MODELS:
**2008** - 2009 (PM) Caliber SRT-4
**2007 - 2008 (PM) Caliber**
**2007 - 2008 (MK) Compass/Patriot**
NOTE:
**This bulletin applies to vehicles built with a 1.8L, 2.0L, 2.4L and 2.4L turbo engine (Sales Codes EBA, ECN, ED3 and ED4) and a engine block heater (sales code NHK) built before February 2, 2009 (MDH 0202xx)**.
NOTE:
**This bulletin does not apply to Japan market vehicles.**
SYMPTOM/CONDITION:
**Some customers may experience a MIL illumination after they have used their engine block heater. Upon further investigation the Technician may find that P2610 - PCM Internal Engine Off Timer Performance has been set.
This is caused by the engine block heater (by design) keeping the engine block warm and the logic in the PCM was expecting a quicker cool down then was actually achieved. The updated software compensates for the use of the engine block heater. **
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTC's other then the one listed above are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
**If the vehicle operator describes or experiences the Symptom/Condition, perform the Repair Procedure. If the engine block heater was not in use when the code was set then it will be necessary to preform the diagnostics available DealerCONNECT/TechCONNECT, Refer To Group 28 - DTC Based Diagnostics > Module - Powertrain Controller > Diagnostic and Testing > P2610 - PCM Internal Engine Off Timer Performance has been set.**
