Steering Column Does Not Telescope In/Out

  1. If power tilt/telescoping steering column diagnostic system check has been performed, go to next step. If power tilt/telescoping steering column diagnostic system check has not been performed, go to POWER TILT/TELESCOPING STEERING COLUMN DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC TESTS.
  2. Connect scan tool to Data Link Connector (DLC). See Figure . Turn ignition on. Using scan tool, select TILT/TELESCOPE MODULE data list. Monitor TELESCOPE/TILT SWITCH parameter. If TELESCOPE/TILT SWITCH parameter is IDLE, go to next step. If TELESCOPE/TILT SWITCH parameter is not IDLE, go to step  5 .
  3. Monitor TELESCOPE/TILT SWITCH parameter while operating tilt/telescoping switch to up and down positions. If TELESCOPE/TILT SWITCH parameter changes as switch is operated, go to next step. If TELESCOPE/TILT SWITCH parameter does not change as switch is operated, go to step  6 .
  4. Monitor TELESCOPE/TILT OUTPUT parameter while operating tilt/telescoping switch to in and out positions. If TELESCOPE/TILT OUTPUT parameter changes as switch is operated, go to next step. If TELESCOPE/TILT OUTPUT parameter does not change as switch is operated, go to step  10 .
  5. Turn ignition off. Disconnect Steering Column Tilt/Telescoping Module (SCCM) connector C4. See Figure . If TELESCOPE/TILT SWITCH parameter is IDLE, go to step  8 . If TELESCOPE/TILT SWITCH parameter is not IDLE, go to step  10 .
  6. Check for open or high resistance in Orange wire between steering column tilt/telescoping switch and SCCM connector C4 terminal "B". See Figure . Check for open or high resistance in Pink wire between steering column tilt/telescoping switch and SCCM connector C4 terminal "C". If circuits are okay, go to step  8 . If faulty circuit is found and repaired, go to step  14 .
  7. Check for open, short to ground or short to voltage in Black wire between telescope actuator and SCCM connector C3 terminal "B". Check for open, short to ground or short to voltage in Red wire between telescope actuator and SCCM connector C3 terminal "C". If circuits are okay, go to step  9 . If faulty circuit is found and repaired, go to step  14 .
  8. Check for poor connections at SCCM connector C4. If connections are okay, go to step  11 . If faulty connections are found and repaired, go to step  14 .
  9. Check for poor connections at SCCM connector C3. If connections are okay, go to step  12 . If faulty connections are found and repaired, go to step  14 .
  10. Check for poor connections at SCCM connector C1. If connections are okay, go to step  13 . If faulty connections are found and repaired, go to step  14 .
  11. Replace tilt/telescoping steering column switch. See STEERING COLUMN TILT/TELESCOPING SWITCH  under REMOVAL & INSTALLATION. After repairs, go to step  14 .
  12. Replace telescope actuator. See STEERING COLUMN MOTORS & SENSORS  under REMOVAL & INSTALLATION. After repairs, go to step  14 .
  13. Replace SCCM. See STEERING COLUMN TILT/TELESCOPING MODULE  under REMOVAL & INSTALLATION. After repairs, go to next step.
  14. Use scan tool to clear DTCs. Recheck operation of tilt/telescoping steering column. Recheck for DTC. If DTC resets, go to step  2 . If DTC does not reset, repair is complete.
