Checking components and wiring

Caution! Do not touch the terminal pins in the parking assistance module (PAM). There is a risk of static discharge. This could damage the parking assistance module (PAM).








- Ignition off
- Disconnect the connector from parking sensor 5 (outer left front)
- Disconnect connector B from the parking assistance module (PAM).
Check the connectors for the parking sensor and the parking assistance module (PAM). Check for damage to pins and terminals. Also check the other connectors that connect the wiring between the parking assistance module (PAM) and the parking sensor.
Remedy as necessary.
Check the signal cable between the parking assistance module (PAM) and the parking sensor connector. Check for a short-circuit to ground. Check for an open-circuit.
Check the cable between:
- Parking assistance module (PAM) terminal #B8 and parking sensor connector terminal #2.
Remedy as necessary.
Check the power supply cable between the parking assistance module (PAM) and the parking sensor connector. Check for a short-circuit to ground. Check for an open-circuit.
Check the cable between:
- Parking assistance module (PAM) terminal #B2 and parking sensor connector terminal #1.
Remedy as necessary.
If no fault is found, replace the parking sensor.
