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
