Tilt/Telescope Actuator Circuit Malfunction
WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector C1 at the telescoping actuator.
- Install a test lamp between the control circuit terminal A and the control circuit terminal B.
- Command the column to telescope in and out using the tilt/telescope switch. The test lamp should illuminate with each command.
- If the test lamp does not illuminate, test both control circuit for a short to ground or an open/high resistance. If the circuits test normal, replace the MSM.
- If all circuits test normal, test or replace the appropriate tilt/telescoping actuator.
