No: TSB-11-13-011

DATE: December, 2011

MODEL: See below

SUBJECT:

POSSIBLE COLD WEATHER ENGINE RPM DROP AND OR UNSTABLE IDLE

PURPOSE

During extremely cold weather (below -4°F, -20°C) some affected vehicles may experience an unstable idle and/or reduced RPM when decelerating to a stop while the engine is warming up.

This TSB provides dealers with a procedure to reprogram the ECM with new software to correct the condition.

IMPORTANT:
If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated and DTCs are listed in the ECM memory (before reprogramming), diagnose and repair those DTCs per the service manual before reprogramming. DO NOT reprogram the ECM until the reason(s) for other DTCs being set is corrected.
