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.
