Diagnostic Fault Information

Circuit Description

When the power seat switches are pressed, they send a 12-volt signal through the switch signal circuits to the memory seat module (MSM). The

MSM then commands the driver seat motors to move in response to the switch signals.

Conditions for Running the DTC

The memory seat module must be powered.

Conditions for Setting the DTC

* If a seat switch circuit is active in one direction and the switch for the opposite direction is pressed, this DTC will set.

* Multiple DTCs will set if one of the switch signal circuits is shorted to voltage.

Action Taken When the DTC Sets

* A motor output driven in response to a switch considered failed, is deactivated for both directions.

* All memory recall commands are ignored.

* The MSM will respond to any other switch signal that has not set a DTC.

Conditions for Clearing the DTC

* The current DTC will clear and set the code to history, 3 seconds after the fault is no longer present and the ignition is cycled OFF then back
