Pinpoint Test H : B1B36:14, B1B38:14, B1B40:14, B1B42:14

H1 RETRIEVE 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 multiple parking aid sensor Diagnostic Trouble Codes (DTCs) recorded?

Yes

GO to H2

No	For DTC B1B36:14, B1B38:14, B1B40:14, or B1B42:14 GO to H3 For all other Diagnostic Trouble Codes (DTCs), REFER to the Diagnostic Trouble Code (DTC) Chart: Parking Aid Module .

H2 CHECK THE BUMPER WIRING HARNESS
- Inspect the bumper wiring harness for opens, shorts, grounds, or corrosion.
Is the bumper wiring harness OK?

Yes GO to H3

No REPAIR or INSTALL a new bumper wiring harness.

H3 CHECK THE SENSOR CIRCUITRY FOR OPENS

Ignition OFF.

Disconnect: Suspect Parking Aid Sensor(s).

Disconnect: PAM connector C4014B.

Is the resistance greater than 10, 000 ohms for the sensor circuit in question?

Yes	If all of the parking aid sensors recorded Diagnostic Trouble Codes (DTCs), GO to H5 If one or more (but not all) parking aid sensor(s) recorded Diagnostic Trouble Codes (DTCs), INSTALL a new sensor(s) for the one(s) in question. REFER to: Front Parking Aid Sensor .

No	REPAIR the circuit in question.

H5 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) - 4-Door . REFER to: Parking Assist Control Module (PAM) - 5-Door .

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.
