WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
- S1 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).
Are parking aid Diagnostic Trouble Codes (DTCs) other than B1B36:96, B1B38:96, B1B40:96 or B1B42:96 recorded?
Yes For all other Diagnostic Trouble Codes (DTCs) REFER to DTC Chart: Parking Aid Module (PAM) No GO to S2 - S2 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS) WITH NO OBJECTS IN FRONT OF THE VEHICLENOTE: Make sure the area around the vehicle is clear of anything that can activate the parking aid system.
- Ignition OFF.
- Clean the front 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) (LFI_DIST, LFO_DIST, RFI_DIST, RFO_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 S3 No GO to S4 - S3 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS) WITH A TEST OBJECT IN FRONT OF THE VEHICLE
- Ignition ON.
- Using a diagnostic scan tool, monitor the PAM parking aid sensor distance Parameter Identifications (PIDs) (LFI_DIST, LFO_DIST, RFI_DIST, RFO_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 front bumper of the vehicle?
Yes GO to S5 No GO to S4 - S4 CHECK THE PARKING AID SENSORS
- Ignition OFF.
- Install a new sensor for the suspect parking aid sensor. REFER to: Front Parking Aid Sensor .
- Ignition ON.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs). Repeat the PAM self-test. Operate the system and verify the concern is still present.
Is the concern still present?
Yes GO to S5 No The cause of the concern was an inoperative parking aid sensor. The system is now operating correctly. - S5 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, BCM guided routine is not applicable for this vehicle and market. Replace the component that was faulted through service information diagnosis. 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.
