Checking components and wiring
Check the connections on the parking assistance module (PAM) and sensor 2 (inner left). Check for contact resistance and oxidation. Also check intermediate connector.
Check the power supply cable between the connector in the parking assistance module (PAM) terminal #6 and the connector for sensor #1. Check for a short-circuit to ground. Check for an open-circuit.
Check the signal ground cable between the connector in the parking assistance module (PAM) terminal #7 and the connector for sensor #3. Check for a short-circuit to supply voltage. Check for an open-circuit.
Check the signal cable between the connector in the parking assistance module (PAM) terminal #3 and the connector for sensor #2. Check for an open-circuit. Check for a short-circuit to supply voltage. Check for a short-circuit to ground.
Try a new sensor if no fault is found.
Remedy as necessary.
