- Remove and disconnect door lock relay. See DOOR LOCK RELAY under REMOVAL & INSTALLATION. Measure resistance between door lock relay terminal No. 5 and terminals No. 2, 4, 7 and 9. See Fig 1 . All resistances should be 150-185 ohms.
- Measure resistance between door lock relay terminal No. 6 and terminals No. 3, 8 and 12. See Fig 1 . All resistances should be less than 5 ohms. If all resistances are as specified, go to next step If resistances are not as specified, replace door lock relay.
- Apply battery positive to relay terminal No. 5 and battery negative to relay terminal No. 1. Measure voltage between battery negative and relay terminal No. 7. See Fig 1 . Apply battery positive to relay terminal No. 5 and battery negative to relay terminal No. 2. Measure voltage between battery negative and relay terminal No. 6.
- Apply battery positive to relay terminal No. 5 and battery negative to relay terminal No. 3. Measure voltage between battery negative and relay terminal No. 4. See Fig 1 . Apply battery positive to relay terminal No. 5 and battery negative to relay terminal No. 8. Measure voltage between battery negative and relay terminal No. 9.
- Voltage in all tests should be greater than 10 volts. If voltage is not as specified, replace door lock relay. If voltages are as specified, relay is functioning properly.

- • 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.
