Diagnosis and Testing

Principle of Operation

For a detailed description of the parking aid system,
REFER to: Parking Aid (413-13, Description and Operation).

Inspection and Verification

CAUTION:
CAUTION:Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
  1. Verify the customer concern.
  1. Visually inspect for obvious signs of electrical damage.
NOTE:
NOTE:Particular attention should be paid to the following items where Diagnostic Trouble Codes (DTCs) may not be logged:
  • Check for contamination (e.g. foreign matter, grime, frosting, ice) around the parking aid sensors, if so clean as necessary.
  • Check for the correct installation and alignment of the sensors to the bumper cover.
  • Spurious detection of the ground may occur during front system operation on an up-slope.

Visual Inspection

Electrical
  • Fuse(s)
  • Relay(s)
  • Wiring Harness
  • Electrical connector(s)
  • Front parking aid sensor(s) and retainers
  • Rear parking aid sensor(s) and retainers
  • Front parking aid speaker
  • Rear parking aid speaker
  • Parking aid switch and LED
  • Reversing lamp switch
  • Parking aid module
  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, check for DTCs and refer to the DTC Index Chart.

DTC Index Chart

NOTE:
NOTE:Generic scan tools may not read the DTCs listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the concern (the last two digits give additional information read by the manufacturer approved diagnostic system).
NOTE:
NOTE:When carrying out voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance always take the resistance of the DMM leads into account.
NOTE:
NOTE:Check and rectify basic concerns before beginning diagnostic routines involving pinpoint tests.
NOTE:
NOTE:Inspect electrical connectors for signs of water ingress, and pins for damage and/or corrosion.
NOTE:
NOTE:If DTCs are recorded and, after carrying out the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose electrical connectors and corroded pins.
