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, actuate the telescope or tilt function through the entire range of travel. The telescope or tilt parameter should display between 0.2 and
4.8 volts.
Circuit/System Testing
Telescope or Tilt Sensor Circuit Malfunction
1. Ignition OFF, disconnect the harness connector X2 at the telescope or tilt actuator.
2. Ignition OFF, test for less than 2.0 ohms between the low reference circuit terminal A 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 B 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 Telescope or 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.
5. Install a 3A fused jumper wire between the signal circuit terminal C and the 5-volt reference circuit terminal B. Verify the scan tool
Telescope or Tilt Sensor parameter is greater than 4.8 volts.
瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace
the MSM.
6. If all circuits test normal, test or replace the telescope or tilt actuator.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
* Steering Column Replacement (See: Steering and Suspension/Steering/Steering Column/Service and Repair/Steering Column Replacement)
* Control Module References (See: Testing and Inspection/Programming and Relearning)for MSM replacement, setup, and programming
