Circuit/System Verification

1. Engine idling at normal operating temperature, verify the scan tool TCM Power up Temperature parameter is between -59 and +165掳C (-74

and +329掳F).

2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the TCM Temperature, TCM Power up Temperature, and the Trans. Fluid

Temp. parameters with a scan tool. The TCM Temperature and the Trans. Fluid Temp. parameters should be within 20掳C (36掳F) of each

other, and the TCM Temperature and TCM Power up Temperature parameters should be within 10掳C (18掳F) of each other.

瀚慖f the TCM Temperature and TCM Power up Temperature parameters are not within 10掳C (18掳F), or the TCM Power up Temperature

and Trans. Fluid Temp. parameters are not within 20掳C (36掳F), replace the control solenoid valve assembly.

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Repair Instructions

Note:

* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and

Inspection/Programming and Relearning) following all transmission related repairs

* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See: Transmission

and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/6T70/6T75 - Automatic

Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).

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 components. 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
