Pinpoint Test

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

1. CHECK THE BUMPER WIRING HARNESS

1. Inspect the bumper wiring harness for opens, shorts, grounds, or corrosion.

Is the bumper wiring harness OK?






2. CHECK THE LH (Left Hand) OUTER PARKING AID SENSOR FOR AN INTERNAL SHORT

1. Ignition OFF.

2. Disconnect: LH (Left Hand) Outer Parking Aid Sensor.

3. Ignition ON.

4. NOTE: It is normal for the sensor open signal DTC (Diagnostic Trouble Code) B1B48:14 to set when carrying out this step. It can be ignored.
Using a scan tool, clear the DTCs (Diagnostic Trouble Codes) and repeat the self-test.

Is DTC (Diagnostic Trouble Code) B1B58:11 still present?






3. CHECK THE RH (Right Hand) OUTER PARKING AID SENSOR FOR AN INTERNAL SHORT

1. Ignition OFF.

2. Disconnect : RH (Right Hand) Outer Parking Aid Sensor.

3. Ignition ON.

4. NOTE: It is normal for the sensor open signal DTC (Diagnostic Trouble Code) B1B44:14 to set when carrying out this step. It can be ignored.
Using a scan tool, clear the DTCs (Diagnostic Trouble Codes) and repeat the self-test.

Is DTC (Diagnostic Trouble Code) B1B58:11 still present?






4. CHECK THE CENTER PARKING AID SENSOR FOR AN INTERNAL SHORT

1. Ignition OFF.

2. Disconnect: Center Parking Aid Sensor.

3. Ignition ON.

4. NOTE: It is normal for the sensor open signal DTC (Diagnostic Trouble Code) B13B5:14 to set when carrying out this step. It can be ignored.
Using a scan tool, clear the DTCs (Diagnostic Trouble Codes) and repeat the self-test.

Is DTC (Diagnostic Trouble Code) B13B5:11 still present?






5. CHECK THE PARKING AID SENSOR VOLTAGE SUPPLY CIRCUIT FOR A SHORT TO GROUND

1. Ignition OFF.

2. Disconnect: PAM (Parking Aid Module) C4014C.

3. Measure:





Is the resistance greater than 10,000 ohms?






6. CHECK THE PARKING AID SENSOR VOLTAGE SUPPLY CIRCUIT AND GROUND CIRCUIT FOR A SHORT TOGETHER

1. Measure:





Is the resistance greater than 10,000 ohms?






7. CHECK FOR CORRECT PAM (Parking Aid Module) OPERATION

1. Ignition OFF.

2. Disconnect and inspect all PAM (Parking Aid Module) connectors.

3. Repair:

- corrosion (install new connector or terminals- clean module pins)
- damaged or bent pins- install new terminals/pins
- pushed-out pins- install new pins as necessary

4. Reconnect the PAM (Parking Aid Module) connectors. Make sure they seat and latch correctly.

5. Operate the system and determine if the concern is still present.

Is the concern still present?
