Pinpoint Test I : B1B36: 96, B1B38: 96, B1B40: 96, B1B42: 96
- NOTE: Before disconnecting the PAM or any of the parking aid sensors, verify the connectors are properly seated and latched.

DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition PAM B1B36: 96 Right Front Outer Sensor: Component Internal Failure A continuous and on-demand DTC that sets in the PAM when the RHF outer parking aid sensor has internally failed or has an incorrect attenuation time. PAM B1B38: 96 Right Front Inner Sensor: Component Internal Failure A continuous and on-demand DTC that sets in the PAM when the RHF inner parking aid sensor has internally failed or has an incorrect attenuation time. PAM B1B40: 96 Left Front Outer Sensor: Component Internal Failure A continuous and on-demand DTC that sets in the PAM when the LHF outer parking aid sensor has internally failed or has an incorrect attenuation time. PAM B1B42: 96 Left Front Inner Sensor: Component Internal Failure A continuous and on-demand DTC that sets in the PAM when the LHF inner parking aid sensor has internally failed or has an incorrect attenuation time. Possible Sources
- Front parking aid sensor
- PAM
- I1 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 Diagnostic Trouble Codes (DTCs) from the self-test.
Are parking aid Diagnostic Trouble Codes (DTCs) other than B1B36: 96, B1B38: 96, B1B40: 96 or B1B42: 96 recorded?
Yes DIAGNOSE other Diagnostic Trouble Codes (DTCs) first. REFER to Diagnostic Trouble Code (DTC) Chart in this information. No GO to I2 - I2 CHECK THE PARKING AID SENSOR OPERATIONNOTE: Make sure the area around the vehicle is clear of anything that can activate the parking aid system.
- Clean the front bumper and sensors with high-pressure water.
- Carry out the azimuth system check. REFER to: Azimuth System Check .
- Carry out the elevation system check. REFER to: Elevation System Check .
Does the parking aid system pass the azimuth system and elevation 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 I3 - I3 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS)
- Make sure the suspect parking aid sensor is flush-mounted in the bezel.
- Ignition ON.
- Using a diagnostic scan tool, monitor the PAM Parameter Identifications (PIDs).
- Monitor and record the parking aid sensor distance Parameter Identifications (PIDs) (LFI_DIST, LFO_DIST, RFI_DIST, RFO_DIST) while moving a test object into and out of the azimuth field for each of the sensors. For an example of an appropriate test object, REFER to: Azimuth System Check .
Do the front parking aid sensor distance Parameter Identifications (PIDs) approximately match the distance from the vehicle to the test object?
Yes GO to I5 No GO to I4 - I4 CHECK THE PARKING AID SENSORS
- Ignition OFF.
- Install a new sensor for the suspect parking aid sensor.
- Ignition ON.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs). Repeat the self-test. Operate the system and verify the concern is still present.
Is the concern still present?
Yes GO to I5 No The cause of the concern was an inoperative parking aid sensor. The system is now operating correctly. - I5 CHECK FOR CORRECT PAM (PARKING ASSIST CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all PAM 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 PAM 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSB addresses this concern, INSTALL a new PAM. REFER to: Parking Assist Control Module (PAM) . 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.
