Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Ignition Switch
Turn ignition off. Disconnect Natural, 5-pin connector C1, or Black 4-pin connector C2, located in steering column. Using DVOM, check for continuity between specified ignition switch terminals with ignition switch in appropriate position. See appropriate IGNITION SWITCH CONTINUITY TEST table. See Fig 1. If continuity does not exist as indicated, replace ignition switch.
