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

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

E1 CHECK THE DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PAM (PARKING ASSIST CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the PAM self-test.
- Check the PAM DTCs (diagnostic trouble codes) from the self-test.
Are parking aid DTCs (diagnostic trouble codes) other than B1B44:96, B1B46:96, B1B48:96 or B1B50:96 recorded?

Yes For all other DTCs (diagnostic trouble codes) REFER to the PAM DTC Chart

No GO to E2

E2 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.
- 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 PID (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 E3

No GO to E4

E3 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS) WITH A TEST OBJECT BEHIND THE VEHICLE

NOTE: Make sure the area around the vehicle is clear of anything that can activate the parking aid system.
- Using a diagnostic scan tool, monitor the PAM parking aid sensor distance PID (LRI_DIST, LRO_DIST, RRI_DIST, RRO_DIST).
- While monitoring the PID 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 E5

No GO to E4

E4 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 DTCs (diagnostic trouble codes) and repeat the PAM self-test.
- Check the PAM DTCs (diagnostic trouble codes).
Is the concern still present?

Yes GO to E5

No INSTALL a new rear parking aid sensor. REFER to: Rear Parking Aid Sensor .

E5 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all BCM and related in-line 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 and related in-line 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 TSB. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSB addresses this concern, Refer to BCM GUIDED ROUTINE . .

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