- With the key out of ignition and with the key in ACC, measure for infinite resistance between the battery positive voltage and the off/run/crank voltage terminals of the ignition switch. Repeat the same measurement between the ignition key resistor signal and the off/run/crank voltage terminals of the ignition switch.
- If less than infinite ohms, replace the ignition switch.
- With the key in ignition, in OFF position, measure for less than 1 ohm between the battery positive voltage and the off/run/crank voltage terminals at the ignition switch.
- If over 1 ohm, replace the ignition switch.
- With the key in the RUN position, measure for less than 1 ohm between the ignition key resistor signal and the off/run/crank voltage terminals at the ignition switch.
- If over 1 ohm, replace the ignition switch.
- With the key in the START position, measure for 1170-1430 ohms between the ignition key resistor signal and the ignition off/run/crank terminals at the ignition switch.
- If out of range, replace the ignition switch.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
