  1. Before installing ignition switch, rotate the slot in the switch to the ON position.
  2. Connect the electrical connector to rear of the ignition switch. Make sure that locking tabs are fully seated into wiring connector.
  3. Position switch (1) to column and install the mounting screws (2). Tighten screw to 3 Nm (26 in. lbs.).
  4. Install the tilt lever bracket (2) mounting screws. Tighten screws to 4.5 Nm (40 in. lbs.).
  5. If the column is non-tilt install the bracket. Tighten screws (2) to 4.5 Nm (40 in. lbs.).
  6. Position the wire retainer into the tilt lever bracket.
  7. Reconnect the lower clockspring connectors.
  8. Install the key cylinder (1)
  9. Install steering column upper and lower shrouds.
  10. Enable the airbag system. Driver Air Bag - Installation.
Ignition Switch - Removal11 steps
⚠ WARNING
The airbag system is a sensitive, complex electro-mechanical unit. Before attempting to diagnose, remove or install the airbag system components you must first disconnect and isolate the battery negative (ground) cable. Then wait two minutes for the system capacitor to discharge. Failure to do so could result in accidental deployment of the air bag and possible personal injury. The fasteners, screws and bolts, originally used for the airbag components, have special coatings and are specifically designed for the airbag system. They must never be replaced with any substitutes. Anytime a new fastener is needed, replace with the correct fasteners provided in the service package or fasteners listed in the parts books.
△ CAUTION
Do not hammer on steering column shaft. This may cause damage to the shaft or bearing.
△ CAUTION
Do not attempt to remove the pivot bolts to disassemble the tilting mechanism.
ℹ NOTE
The ignition key must be in the key cylinder for cylinder removal. The key cylinder must be removed first before removing ignition switch.

  1. Remove the negative (ground) cable from the battery.
  2. Disable the airbag, Driver Air Bag - Removal.
  3. Remove the lower and upper shrouds.
  4. Remove key cylinder. Ignition Lock Cylinder - Removal.
  5. Disconnect the lower clockspring connectors.
  6. Remove the wire retainer from the tilt lever bracket.
  7. Remove the tilt lever mounting screws to gain access to the ignition switch (1) mounting screws.
  8. For columns without tilt remove the bracket (2) to gain access to the ignition switch mounting screws (1).
  9. Disconnect the electrical connector at rear of ignition switch (1).
  10. Remove ignition switch mounting screws (2).
  11. Using a small screwdriver, push on locking tab and remove switch from steering column.

⚠ WARNING
On vehicles equipped with airbags, refer to electrical - passive restraint systems before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury.
  1. Disconnect and isolate the battery negative cable. Remove the steering column shrouds. Unplug the key-in ignition switch wire harness connector from the ignition switch.
  2. Check for continuity between the key-in switch sense circuit and the left front door jamb switch sense circuit terminals of the key-in ignition switch. There should be continuity with the key in the ignition cylinder, and no continuity with the key removed from the ignition cylinder. If OK, go to 3. If not OK, replace the faulty ignition switch assembly.
  3. Check for continuity between the left front door jamb switch sense circuit cavity of the key-in ignition switch wire harness connector and a good ground. There should be continuity with the driver door open, and no continuity with the driver door closed. If OK, see the diagnosis for Instrument Cluster. If not OK, repair the circuit to the driver door jamb switch as required.
