Power Tilt/Telescopic Steering Control Unit Input Test/Replacement

  1. Turn the ignition switch to LOCK (0).
  2. Remove the driver's dashboard undercover (see DRIVER'S DASHBOARD UNDERCOVER REMOVAL/INSTALLATION ) and the driver's dashboard lower cover (see INSTRUMENT FASCIA REMOVAL/INSTALLATION ), then remove the steering column covers (see STEERING COLUMN REMOVAL AND INSTALLATION ).
  3. Disconnected the 16P connector (A) and the 8P connector (B) from the power tilt/telescopic steering control unit (C).

  4. Inspect the connector and socket terminals to be sure they are all making good contact.
    • 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 the following input tests.
    • If any test indicates a problem, find and correct the cause, then recheck the system.
    • If all the input tests prove OK, the control unit must be faulty; replace it.
