Harness Shorts
The purpose is to check the harness for short circuits (to ground or voltage).
- Key OFF.
- Disconnect the component from the vehicle harness.
- Using an ohmmeter, measure the resistance between the signal circuit and signal return circuit, power ground circuit, VREF circuit, or vehicle power.
- If the resistance value is less than 10,000 ohms, the 2 circuits are shorted.
