    • Are the resistances less than 5 ohms? 
      • Yes  : GO to B4.
      • No  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test.
  4. B4 CHECK THE SENSOR CIRCUITRY FOR SHORTS TO GROUND 
    • Measure the resistance between the suspect parking aid sensor, harness side and ground as follows:
      DTC Rear Sensor Connector-Pin Circuit
      B1B44:01, 96 RH outer C4011-1 VMP17 (YE/OG)
      B1B46:01, 96 RH inner C4012-1 VMP16 (YE/GY)
      B1B48:01, 96 LH outer C4009-1 VMP15 (YE/GN)
      B1B50:01, 96 LH inner C4010-1 VMP14 (WH/OG)

    • Is the resistance greater than 10, 000 ohms? 
      • Yes  : GO to B5.
      • No  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test.
  5. B5 CHECK THE PARKING AID SENSOR CIRCUITRY FOR A SHORT TOGETHER 
    • Measure the resistance between the suspect parking aid sensor pins, harness side as follows:
      DTC Parking Aid Sensor Connector-Pin/Circuit Connector-Pin/Circuit
      B1B44:01, 96 RH outer C4011-1 VMP17 (YE/OG) C4011-3 RMP07 (GN/WH)
      B1B46:01, 96 RH inner C4012-1 VMP16 (YE/GY) C4012-3 RMP07 (GN/WH)
      B1B48:01, 96 LH outer C4009-1 VMP15 (YE/GN) C4009-3 RMP07 (GN/WH)
      B1B50:01, 96 LH inner C4010-1 VMP14 (WH/OG) C4010-3 RMP07 (GN/WH)

    • Is any voltage present? 
      • Yes  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test.
      • No  : If all of the parking aid sensors recorded DTCs, GO to B7.

        If one or more parking aid sensor(s) recorded DTCs, INSTALL a new sensor(s) for the one in question. REFER to Parking Aid Sensor  . CLEAR the DTCs. REPEAT the self-test.

  7. B7 CHECK FOR CORRECT PAM OPERATION 
    • Disconnect the PAM connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the PAM connector and make sure it seats correctly.
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
      • Yes  : INSTALL a new PAM. REFER to Parking Aid Module (PAM)  . TEST the system for normal operation.
      • No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
