Inspection and Verification

Verify the customer concern by operating the ignition switch and the multifunction switch.
Visually inspect the ignition switch and the steering column multifunction switch for damage; refer to the following chart: Visual Inspection Chart VISUAL INSPECTION CHART Mechanical Electrical Ignition switch Turn signal switch (part of the steering column multifunction switch) Hazard flasher switch Wiper/washer switch Connections Battery junction box (BJB) fuse MAIN (120A) 19 (40A) 20 (40A) Central junction box (CJB) fuse IG KEY 11 (10A) Circuitry
If binding occurs, turn the steering wheel left or right to release any pressure on the ignition switch and make sure the ignition key is cut correctly.
If the cause of the switch concern is not visually evident, proceed to the Symptom Chart.
