Pinpoint Test Q: B1B44:96, B1B46:96, B1B48:96, B1B50:96

Q1 CHECK THE DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PAM (PARKING ASSIST CONTROL MODULE) SELF-TEST
- Ignition ON.
- Using a diagnostic scan tool, perform the PAM self-test.
- Check the PAM Diagnostic Trouble Codes (DTCs) from the self-test.
Are parking aid Diagnostic Trouble Codes (DTCs) other than B1B44:96, B1B46:96, B1B48:96 or B1B50:96 recorded?

Yes For all other Diagnostic Trouble Codes (DTCs) Refer to the DTC Chart(s) .

No GO to Q2

Q2 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS) WITH NO OBJECTS BEHIND THE VEHICLE

NOTE: Make sure the area around the vehicle is clear of anything that can activate the parking aid system.
- Ignition OFF.
- Clean the rear bumper and sensors with high-pressure water.
- Make sure the suspect parking aid sensor(s) is flush-mounted in the bezel.
- Ignition ON.
- Using a diagnostic scan tool, monitor the PAM parking aid sensor distance Parameter Identifications (PIDs) (LRI_DIST, LRO_DIST, RRI_DIST, RRO_DIST). The PID reads 2, 540 mm (100 in) on a correctly functioning sensor.
Does the PID read 2, 540 mm (100 in)?

Yes GO to Q3

No GO to Q4

Q3 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS) WITH A TEST OBJECT BEHIND THE VEHICLE
- Using a diagnostic scan tool, monitor the PAM parking aid sensor distance Parameter Identifications (PIDs) (LRI_DIST, LRO_DIST, RRI_DIST, RRO_DIST).
- While monitoring the Parameter Identifications (PIDs), move a test object into and out of the detection zone behind each sensor. For an example of a test object, Refer to: Azimuth System Check .
Does the PID approximately match the distance from the test object to the rear bumper of the vehicle?

Yes GO to Q5

No GO to Q4

Q4 CHECK THE PARKING AID SENSORS

Ignition OFF.

Install a known good sensor for the suspect parking aid sensor. Refer to: Rear Parking Aid Sensor .

Ignition ON.

Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) and repeat the PAM self-test.

Is the concern still present?

Yes

GO to Q5

No	The cause of the concern was an inoperative parking aid sensor. The system is now operating correctly.

Q5 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all BCM connectors.

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

Reconnect the BCM connectors. Make sure they seat and latch correctly.

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

Is the concern still present?

Yes	CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern,

No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
