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 Continuity Test
Measure resistance between ignition switch connector terminals. See Fig 1. Ensure resistance is within specification. See IGNITION SWITCH RESISTANCE SPECIFICATIONS . If switch resistance does not meet specifications, replace switch assembly.
| Ohmmeter Connection | Ignition Switch Position | Resistance |
|---|---|---|
| ..... | Lock | 10,000 Ohms Or More |
| 2-3 | Accessory | Less Than 1 Ohm |
| 2-3 | On | Less Than 1 Ohm |
| 2-4 | On | Less Than 1 Ohm |
| 6-7 | On | Less Than 1 Ohm |
| 1-2 | Start | Less Than 1 Ohm |
| 1-4 | Start | Less Than 1 Ohm |
| 6-7 | Start | Less Than 1 Ohm |
