Inspection and Verification

1. Verify the customer concern.

1. Visually inspect the following for obvious signs of electrical damage. Visual Inspection Chart Electrical
   • Central junction box (CJB) fuse 26 (7.5A)
   • Circuitry
   • Parking aid sensors
   • Parking aid disable switch and LED
   • Parking aid speaker
   • Reversing lamps

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 visusally evident, connect the diagnostic tool to the data link connector and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
   • check that the program card is correctly installed.
   • check the connections to the vehicle.
   • check the ignition switch position.

1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.

1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
   • SCP+, SCP-, UBP or ISP circuit fault; all electronic control units no response/not equipped, refer to Section 418-00 .
   • No response/not equipped for parking aid module, Go To Pinpoint Test BC .
   • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the parking aid module.

1. If the DTCs retrieved are related to the concern, go to the Parking Aid Module Diagnostic Trouble Code (DTC) Index.

1. If no DTCs related to the concern are retrieved, GO to Symptom Chart to continue diagnostics

Believe it or not, the master switch could have failed. This may or may not work, especially if the master switch receives power first and then provides power to each individual switch. Try each window at each door to see if they respond. If they do, then the problem is very likely at the driver's door switch itself. Next if the other doors are inactive at their respective switches, remove the driver's switch from the arm rest and take a test light and backprobe the red wire which is usually the main power feed and check for power, If there is power present, then attach your test light's alligator clip to the red wire, then take the point and back probe the black wire to confirm there is ground to the switch. If the test light doesn't light up, then take a jumper wire and attach one end to a reliable ground source, then temporarily backprobe the black wire with the jumper wire, and try the switch. Now keep in mind that the window switch also has other wires that are bidirectional, which are outputs. They usually are brown and blue. Can you get your hands on a wiring diagram? Also if you offer the year, make and model of your vehicle, it would be helpful as it would allow others to give you vehicle specific instructions.

Can a head phone be plug into the unit and if so - can you hear sound over the head phone. Also first look if nothing is stuck in the head phone jack (where it is plugged in as kids tend to stuff small objects into it). If sound can be heard over the head phones the unit is ok. The problem then lies with in the speaker output circuitry. The speaker output wiring has most of the time a inbuilt fuse that protects the circuitry when the speaker wires are shorted out when power (volume) is on. The unit has to be opened to replace it by a knowledgeable person.

lubricating rubber or plastic makes the wear worse replace the worn or failing parts
