Steering Column Lock and Ignition Cylinder

Ignition Cylinder Wire Routing:

The ignition cylinder in vehicles equipped with the PASS-Key II system contains a set of electrical contacts used to measure the resistor in the ignition key. When servicing the ignition cylinder, be certain to maintain proper wire routing. A two pin connector at the base of the steering column connects the contacts to the vehicle wiring. The connector is also used for diagnostic purposes. The ignition cylinder also performs all functions of ignition cylinders on non-PASS-Key II vehicles. When replacing an ignition cylinder, it will he necessary to make new ignition keys which match the PASS-Key II key code of the BCM and the mechanical cut of the new ignition cylinder.

Important
^ The wire routing for the contacts inside the steering column is critical.
