Diagnostic Fault Information

Circuit Description

The memory seat module (MSM) determines the position of the steering column based on inputs received from the tilt position sensors built into

the tilt actuators. The MSM supplies a 5-volt reference and a low reference to the sensors and monitors the column position via the steering column

tilt sensor signal circuit.

Conditions for Running the DTC

Ignition ON

Conditions for Setting the DTC

B2880 01

The steering column tilt sensor signal voltage is greater than 4.8 volts for more than 2 seconds.

B2880 06

The steering column tilt sensor signal voltage is less than 0.2 volt for more than 2 seconds.

B2880 5A

An incorrect steering column tilt sensor signal voltage is seen.

B2880 61

The steering column tilt sensor signal voltage does not change when the tilt actuator is commanded.

Action Taken When the DTC Sets

Steering column tilt operations are suspended.
