DTC Fault Trigger Conditions






Pinpoint Test

1. CHECK THE DTCs (Diagnostic Trouble Codes) FROM THE PAM (Parking Aid Module) SELF-TEST

1. Using a scan tool, perform PAM (Parking Aid Module) self-test.

2. Check the PAM (Parking Aid Module) DTCs (Diagnostic Trouble Codes) from the self-test.

Are parking aid DTCs (Diagnostic Trouble Codes) other than B1B36:96, B1B38:96, B1B40:96 and B1B42:96 recorded?






2. CHECK THE PARKING AID SENSOR OPERATION

NOTE: Make sure the area around the vehicle is clear of anything that can activate the parking aid system.

1. Clean the rear bumper and sensors with high-pressure water.

2. Carry out the azimuth system check. REFER to Azimuth System Check Azimuth System Check.

Does the parking aid system pass both system checks?






3. CHECK THE PARKING AID SENSOR DISTANCE PIDs (Parameter Identifications)

1. Make sure the suspect parking aid sensor(s) is flush-mounted in the bezel.

2. Ignition ON.

3. Using a scan tool, view PAM (Parking Aid Module) PIDs (Parameter Identifications).

4. With the brake pedal applied, shift the transmission into reverse and monitor the parking aid sensor distance PID (Parameter Identification) (LFI_DIST, LFO_DIST, RFI_DIST, RFO_DIST). The PID (Parameter Identification) reads 2,540 mm (100 in) on a correctly functioning sensor.

Does the PID (Parameter Identification) read 2,540 mm (100 in)?






4. CHECK THE PARKING AID SENSORS

1. Install a new sensor for the suspect parking aid sensor. REFER to Parking Aid Sensor. Parking Aid Sensor

2. Ignition ON.

3. Using a scan tool, clear the DTCs (Diagnostic Trouble Codes). Repeat the self-test. Operate the system and verify the concern is still present.

Is the concern still present?






5. 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?
