Diagnostic Fault Information
Circuit Description
The memory seat module (MSM) determines the position of the steering column based on inputs received from the tilt or telescope position sensors
built into the tilt or telescope 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 or telescope sensor signal circuit.
Conditions for Running the DTC
Ignition ON
Conditions for Setting the DTC
B2860 01
The steering column telescope sensor signal voltage is greater than 4.8 volts for more than 2 seconds.
