Circuit/System Verification
Ignition ON, view the appropriate scan tool Tilt or Telescope Switch parameter while cycling the appropriate switch between states.The parameter
should change between Active and Inactive.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the tilt/telescope switch.
2. Ignition ON, verify a test lamp illuminates between terminal 4 and ground.
瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
3. Verify with the scan tool that the appropriate switch parameter is Inactive.
瀚慖f not the specified value, test the appropriate signal circuit for a short to voltage. If the circuit tests normal, replace the MSM.
4. Install a 3A fused jumper wire between the appropriate circuit terminal 1, 2, 3, or 5 and terminal 4. Verify with the scan tool that the
appropriate switch parameter is Active.
瀚慖f not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the
MSM.
5. If all circuit test normal, test or replace the tilt/telescope switch.
Component Testing
Tilt/Telescope Switch
1. Ignition OFF, disconnect the harness connector at the tilt/telescope switch.
2. Test for infinite resistance between terminals 1, 2, 3, and 5 with the switch in the neutral position:
瀚慖f less than the specified range, replace the tilt/telescope switch.
3. Test for less than 1 ohm between terminal 4 and terminals 1, 2, 3, and 5 with the switch in each appropriate position.
瀚慖f greater than the specified value, replace the tilt/telescope switch.
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
