Function And Benefits
- Processes input from ultrasonic parking sensors and controls driver alerts (beeps and dashboard indicators).
- Restores reliable parking assistance after sensor or module failure.
- Suitable for repair shops and competent DIY repairs where part-number matching is used for fitment.
- Helps eliminate false alarms or complete loss of park assist when the control unit is the root cause.
Common Symptoms Of A Faulty Unit
Typical signs that the control unit may be failing include no response from parking sensors, constant or intermittent beeping, false proximity alerts, error messages related to park assist on the instrument cluster, or the park assist system being unavailable.
Causes Of Failure
Failures are most often caused by moisture ingress, corrosion at connectors, impact damage from collisions, wiring short circuits, or internal electronic component degradation over time. Environmental exposure and faulty sensor wiring can accelerate wear.
Replacement And Installation Notes
Replacement typically involves disconnecting the vehicle battery, locating the existing control unit (location varies by model but is often in the rear bodywork or luggage compartment area), unplugging the connectors and replacing the unit. After mechanical installation, the new module may require registration or coding to the vehicle and pairing with the sensors using a compatible diagnostic tool (for example factory or aftermarket PSA diagnostic software). If you are not experienced with vehicle electronics and coding, professional installation is recommended to ensure full system functionality.
