* 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.
