This is an internal fault detection of the control solenoid (w/body and TCM) valve assembly. This fault is carried out inside the control solenoid (w/body and TCM) valve assembly and no external circuits are involved.
• | The control solenoid (w/body and TCM) valve assembly runs the program to detect an internal fault when the key is ON or the engine is running. |
• | Ignition voltage is between 8.6-18.0 volts - DTC P062F only. |
The read only memory (ROM) test has failed 5 or more times.
The transmission control module (TCM) has detected no start program.
The TCM has detected a memory checksum error.
The TCM random access memory (RAM) test has failed 5 or more times.
The TCM has detected non-volatile memory is incorrect during power-down.
• | DTCs P0601, P0602, P0603, P0604, and P062F are Type A DTCs. |
• | The TCM shifts to a default gear, shuts down, and turns OFF. |
DTCs P0601, P0602, P0603, P0604, and P062F are Type A DTCs.
When attempting to set TCM internal DTCs let the engine run for at least 1 minute and then shut the engine off for at least 30 seconds. Following this procedure will allow a complete TCM shutdown. Reprogram the TCM and retest the DTC to see if the DTC resets.

Powertrain Diagnostic Trouble Code (DTC) Type Definitions
Reprogram the TCM and recheck for DTCs.
⇒ | If the DTC resets, replace the control solenoid (w/body and TCM) valve assembly. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
Perform the Service Fast Learn Adapts if internal transmission repairs are performed.
