Circuit/System Description

The memory seat module (MSM) monitors the current supplied to the driver seat adjuster motors, recline motor and the lumbar motors. It can detect

both absolute and differential current levels from the seat motors. Absolute current is the maximum allowable current the module will supply to the

motors. A differential current mismatch occurs when the current supplied to the seat motors does not match the current returning from the motors.

Conditions for Running the DTC

The seat adjuster motors, recline motor or the lumbar motor must be active.

Conditions for Setting the DTC

B1335 0B

The absolute current or an over-current has exceeded the maximum value allowed.

B1335 42

This DTC will set if the module calibration is not programmed.

B1335 4B

This DTC will set if the module calibration is out of range.

Action Taken When the DTC Sets

All movement related to the seat cushion motors, recline and driver seat lumbar motors is aborted.

Conditions for Clearing the DTC

* The current DTC will clear and set the code to history, 3 seconds after no motor movement is requested or the current is no longer

mismatched, and the ignition is cycled OFF then back to ACC or RUN.

* The history DTC will clear after 50 consecutive fault-free ignition cycles have occurred.
