Action Taken When the DTC Sets

WARNING: This page is about a different car, the 2007 GMC Yukon XL and 2007 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.

The TCM does not request the engine control module (ECM) to illuminate the malfunction indicator lamp (MIL).
The TCM commands increased line pressure.
The TCM freezes transmission adaptive functions.
The TCM determines a default TFT using the following matrix:
- If the engine run time is less than 60 seconds then default TFT equals 47°C (117°F).
- If ECT is less than 20°C (68°F), then default TFT equals IAT.
- If the ECT is 20-110°C (68-230°F) then default TFT equals ECT.
- If ECT and TFT DTCs are both set then default TFT is 140°C (284°F).
The TCM records the operating conditions when the Conditions for Setting the DTC are met. The TCM stores this information as Failure Records.
The TCM stores DTC P0712 in TCM history.
