DTC B2880 5A



- Tilt Position Sensor Circuit Plausibility Failure



DTC B2880 61



- Tilt Position Sensor Actuator Stuck



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.



B2860 06



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



B2860 5A



An incorrect steering column telescope sensor signal voltage is seen.



B2860 61



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



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 telescope actuator is commanded.
