DTC Fault Trigger Conditions






Pinpoint Test

1. CHECK THE CONNECTORS FOR CORRECT LATCHING AND THE BUMPER WIRING HARNESS FOR DAMAGE

1. Inspect the PAM (Parking Aid Module) and sensor connectors for correct latching by pulling on the latched connector.

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

Are the connectors correctly latched and the bumper wiring harness OK?








2. CHECK THE LEFT OUTER PARKING AID SENSOR FOR AN INTERNAL SHORT

1. Ignition OFF.

2. Disconnect: Left Outer Parking Aid Sensor.

3. Ignition ON.

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

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








3. CHECK THE RIGHT OUTER PARKING AID SENSOR FOR AN INTERNAL SHORT

1. Ignition OFF.

2. Disconnect: Right Outer Parking Aid Sensor.

3. Ignition ON.

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

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








4. CHECK THE LEFT INNER PARKING AID SENSOR FOR AN INTERNAL SHORT

1. Ignition OFF.

2. Disconnect: Left Inner Parking Aid Sensor.

3. Ignition ON.

4. NOTE: It is normal for DTC (Diagnostic Trouble Code) B1B50:14 to set when carrying out this step. It should be ignored.
Using a scan tool, clear the DTCs (Diagnostic Trouble Codes) and repeat the on-demand self-test.

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








5. CHECK THE RIGHT INNER PARKING AID SENSOR FOR AN INTERNAL SHORT

1. Ignition OFF.

2. Disconnect: Right Inner Parking Aid Sensor.

3. Ignition ON.

4. NOTE: It is normal for DTC (Diagnostic Trouble Code) B1B46:14 to set when carrying out this step. It should be ignored.
Using a scan tool, clear the DTCs (Diagnostic Trouble Codes) and repeat the on-demand self-test.

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








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

1. Ignition OFF.

2. Disconnect: PAM (Parking Aid Module).

3. Measure:





Is the resistance greater than 10,000 ohms?








7. 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?








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

1. Disconnect and inspect the PAM (Parking Aid Module) connector.

2. 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

3. Reconnect the PAM (Parking Aid Module) connector. Make sure it seats and latches correctly.

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

Is the concern still present?
