If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
-
If the terminals look OK, go to step 5.
5. Reconnect the connectors to the power tilt/telescopic steering control unit, and do these input tests at the connectors.
-
If any test indicates a problem, find and correct the cause, then recheck the system.
