Circuit/System Description

The seat memory control module supplies a reference voltage to each signal circuit of the driver seat adjuster switch. When the power seat switches

are pressed, the appropriate signal circuit from the seat memory control module is pulled low through the switch contacts indicating the power seat

command. The seat memory control module then commands the driver seat to move in response to the switch signals.

Conditions for Running the DTC

* DTC B1325 must not be present.

* Module battery voltage must be between 9 - 16 V.

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.

* A short to ground on a switch signal circuit.

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 seat memory control module 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, when the fault is no longer present and the ignition is cycled OFF then back to ACC

or RUN.

* The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.

Diagnostic Aids

* If one of the switch signal circuits is shorted to ground, multiple codes will set.

* If a switch is stuck in one direction and the switch is pressed in the opposite direction, a single code will set.
