Parking Assist System Faults

Has your vehicle suddenly displayed a Parking Assist System Fault, Parking Sensor Fault, Park Assist Unavailable, PDC Failure or similar warning? We provide professional parking assist diagnostics and fault finding for all makes and models.

Common Symptoms

Perhaps your parking sensors have stopped working completely, you're getting a continuous tone, one sensor isn't detecting obstacles, or the system works intermittently.

At OBD_PAL, we provide professional parking assist system diagnostics and fault finding for all makes and models.

What Can Cause a Parking Assist Fault?

Modern parking assistance systems use multiple components which communicate with each other. A fault with just one component can sometimes disable the entire system. Common causes include:

  • Faulty parking sensor
  • Damaged or corroded wiring
  • Poor electrical connections
  • Water ingress
  • Damaged sensor connectors
  • Parking assist control unit failure
  • Incorrectly fitted or incompatible sensors
  • Sensor alignment or calibration issues
  • Software or coding faults
  • Low vehicle battery voltage
  • Communication faults between control units
  • Damage following bumper removal, repair or replacement

How Do We Rectify It?

At OBD_PAL, we start with correct diagnostics. Rather than simply replacing parking sensors until the warning disappears, we diagnose the system to establish the actual cause of the fault.

Depending on the vehicle and fault, this can include checking diagnostic trouble codes, individual sensor operation, wiring and connections, power supplies, communication networks, coding and software.

What the Repair Involves

Parking Sensor Testing

If an individual parking sensor is suspected, its operation can be tested to determine whether the sensor itself has failed or whether the problem lies elsewhere in the system.

Wiring & Electrical Fault Finding

Parking sensors are mounted in an exposed area of the vehicle, making wiring, connectors and components vulnerable to water, corrosion and physical damage. We carry out electrical testing to locate wiring and connection faults rather than unnecessarily replacing components.

Control Unit Diagnostics

If the parking assist control module is reporting internal or communication faults, further testing can determine whether the module, its power supply, wiring or another component is responsible.

Coding, Programming & Software

Replacement components on some vehicles may require coding, programming or configuration before they will operate correctly. Software-related faults can also occur, particularly on newer vehicles with more advanced parking assistance systems.

Calibration & System Setup

Vehicles equipped with more advanced parking assistance technology may require calibration or setup procedures following component replacement, accident repairs or bumper work.

Don't Guess — Diagnose It Properly

A Parking Assist System Fault doesn't automatically mean you need new parking sensors. A failed sensor may be the cause — but so can damaged wiring, water ingress, a control unit problem, incorrect coding or a software issue.

At OBD_PAL, we diagnose the system properly before recommending repairs.
