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 the rack-and-pinion actuator in the lock cylinder housing
• Insufficient lube on actuator

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

• Binding ignition switch
