1. Clear the DTC information.

2. Ignition OFF for 1 minute.

3. Ignition ON.

4. Retest for DTCs P1B15.

Circuit/System Testing

Program the PIM with the latest software version and recheck for DTCs.

If the DTC resets after programming or if the PIM already contains the latest software version, replace the PIM.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

DTC Descriptors

DTC P06AC

- Transmission Control Module (TCM) Power Up Temperature Sensor Performance

DTC P06AD

- Transmission Control Module (TCM) Power Up Temperature Sensor Circuit Low Voltage

DTC P06AE

- Transmission Control Module (TCM) Power Up Temperature Sensor Circuit High Voltage

Circuit/System Description

The transmission control module (TCM) power up temperature sensor is located inside of the control solenoid valve assembly which has no

serviceable parts. The TCM power up temperature sensor provides the temperature of the TCM when the TCM power is on. This temperature

reading is used in various shifting and diagnostic routines and also to protect the control solenoid valve assembly and TCM. This fault is handled

inside the TCM and no external circuits are involved.
