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.
