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.

Conditions for Clearing the DTC

* A current DTC will clear when the malfunction is no longer present

* A history DTC will clear after 50 malfunction-free ignition cycles.

Circuit/System Verification

Ignition ON, command the tilt motor UP and DOWN with a scan tool. The reading should be between 0.2 and 4.8 volts.

Circuit/System Testing

Tilt Sensor Circuit Malfunction

1. Ignition OFF, disconnect the harness connector at the tilt actuator.

2. Ignition OFF, test for less than 10.0 ohms between the low reference circuit terminal E and ground.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the MSM.

3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal D and ground.

瀚慖f less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal,

replace the MSM.

瀚慖f greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the MSM.

4. Verify the scan tool Tilt Sensor parameter is less than 0.2 volt.

瀚慖f greater than the specified range, test the signal circuit terminal C for a short to voltage. If the circuit tests normal, replace the MSM.
