DTC P062F
- Transmission Control Module (TCM) Long Term Memory Performance
Circuit/System Description
This is an internal fault detection of the transmission control module. This fault is handled inside the transmission control module and no external
circuits are involved. The transmission control module is part of the control solenoid valve assembly, and is not serviced separately.
Conditions for Running the DTC
* The control solenoid valve assembly runs the program to detect an internal fault when the key is ON or the engine is running.
* Ignition voltage is 8-18 V.
Conditions for Setting the DTC
The control solenoid valve assembly has detected an internal malfunction.
Action Taken When the DTC Sets
* DTCs P0601, P0602, P0603, P0604, P0606, P060B and P062F are Type A DTCs.
* The transmission control module shifts to a default gear and turns OFF.
Conditions for Clearing the DTC
DTCs P0601, P0602, P0603, P0604, P0606, P060B and P062F are Type A DTCs.
Diagnostic Aids
When attempting to set transmission control module internal DTCs, run the engine for at least 1 minute, and then shut the engine off for 30
seconds. Following this procedure will allow for a complete transmission control module shutdown.

Circuit/System Verification
Verify that DTC P0601, P0602, P0603, P0604, P0606, P060B, or P062F is not set.
If the DTC is set, program the Q8 control solenoid valve assembly. If the DTC resets, replace the Q8 control solenoid valve assembly.
Component Testing
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/2ML70 - Automatic Transmission/Control Solenoid
Valve and Transmission Control Module Assembly Inspection).
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
