Pinpoint Test D

1. Check the PAM DTCs  from the self-test.

Are parking aid DTCs other than B1B44:96, B1B46:96, B1B48:96 and B1B50:96 recorded? 

• Yes: DIAGNOSE the other DTCs  first. REFER to DTC Chart: Parking Aid Module (PAM) .
• No: GO to 2  .

1. Clean the rear bumper and sensors with high-pressure water.
2. Carry out the azimuth system check. REFER to Azimuth System Check .
3. Carry out the elevation system check. REFER to Elevation System Check .

Does the parking aid system pass both system checks? 

• Yes: The system is operating correctly at this time. The concern may have been caused by a dirty or blocked parking aid sensor.
• No: GO to 3  .

1. Install a new parking aid sensor for the sensor in question. REFER to Parking Aid Sensor .
2. Ignition ON.
3. Using a scan tool, clear the DTCs  and repeat the self-test.
4. Operate the system and verify the concern is still present.

Is the concern still present? 

• Yes: GO to 4  .
• No: The cause of the concern was the parking aid sensor. The system is now operating correctly.

1. Disconnect and inspect the PAM 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 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? 

• Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs  address this concern, INSTALL a new PAM. REFER to Parking Aid Module (PAM) .
• No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
