DTC Descriptor

DTC P16F8

- Control Module Clutch Command Incorrect

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 transmission control module has detected an internal malfunction.

Action Taken When the DTC Sets

* DTC P16F8 is a Type A DTC.
