Ignition Switch Mechanical Test

Mechanical Test

Test the steering column ignition system mechanical operation by rotating the lock cylinder/key through all switch positions. The movement should feel smooth with no sticking or binding. The ignition system should return from the START position back to the RUN position without assistance (spring return). If sticking or binding is encountered, check for the following:

- Burrs on the lock cylinder key

- Binding lock cylinder

- Shroud rubbing against lock cylinder

- Burrs or foreign material around rack-and-pinion actuator in lock cylinder housing

- Insufficient lube on actuator

- Binding ignition switch

NOTE: Do not apply lubricant to the inside of the ignition switch.
