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.
