Circuit/System Verification
1. Ignition ON, clear the DTCs with a scan tool.
2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the TCM Power-Up Temperature parameter and the TCM Temperature
parameter with a scan tool. The TCM Power-Up Temperature parameter and the TCM Temperature parameter should be within 10锟斤拷C (18锟斤拷F)
of each other.
锟斤拷If the TCM Power-Up Temperature parameter is not within the specified value of the TCM Temperature parameter, then replace the Q8
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
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
* Control solenoid valve assembly replacement. Refer to Control Module References (See: Testing and Inspection/Programming and
Relearning) for replacement, setup, and programming.
* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and
Inspection/Programming and Relearning) following all transmission related repairs.
P06AD
DTC P06AC, P06AD, or P06AE
Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System
Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an
overview of the diagnostic approach.
* Diagnostic Procedure Instructions (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic Procedure
Instructions) provides an overview of each diagnostic category.
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.
Conditions for Running the DTC
P06AC
* DTCs P06AC, P0716, P0717, P0722, or P0723 are not set.
* The engine speed is 500 RPM or greater for 5 seconds.
* The ignition voltage is 8.6 volts or greater.
* The TCM power up temperature is between -40 and +150锟斤拷C (-40 and +302锟斤拷F).
P06AD
* DTCs P06AD, P0716, P0717, P0722, or P0723 are not set.
* The transmission output shaft speed is 200 RPM or greater for 4 minutes.
* The torque converter clutch (TCC) slip speed is 120 RPM or greater for 4 minutes.
