Circuit/System Description

The memory seat module (MSM) supplies a 5-volt reference voltage to the driver seat, adjustable pedal, and the tilt steering wheel position sensors.

The MSM monitors this reference voltage to ensure the accuracy of the voltages being returned from the sensors. If the voltage exceeds the normal

operating range, errors will occur in the memory recall operations of the seat, adjustable pedals, and steering wheel.

Conditions for Running the DTC

The memory seat module must be powered.

Conditions for Setting the DTC

The following conditions exist for more than 1 second:

B1395 02

The reference voltage drops below 4.8 volts for more than 300 mS.

B1395 05

The reference voltage exceeds 5.2 V for more than 300 mS.

Action Taken When the DTC Sets

All memory recall functions will be disabled.

Conditions for Clearing the DTC

* The current DTC will clear 3 seconds after the reference voltage returns to normal operating range, and the ignition is cycled OFF then back

to ACC or RUN.

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

Diagnostic Aids

An internal short to ground in one of the position sensors may set this DTC.
