PINPOINT TEST B: DTCs C1700, C1703 AND C1706

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. B1 RETRIEVE THE DTCs FROM THE PAM SELF-TEST 
    • Check the PAM DTCs from the continuous and on-demand self-tests.
    • Are multiple DTCs recorded? 
      • Yes:  GO to B2.
      • No:  For DTC C1700, C1703 or C1706 GO to  B3.

        For all other DTCs, REFER to DTC Charts  .

  2. B2 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 B3.
      • No:  REPAIR or INSTALL a new bumper wiring harness. CLEAR the DTCs. TEST the system for normal operation.
  3. B3 CHECK THE SENSOR CIRCUITRY FOR OPENS 
    • Ignition OFF.
    • Disconnect: Suspect Parking Aid Sensor C4009, C4011 or C4228.
    • Disconnect: PAM C4014.
    • Measure the resistance between the PAM C4014, harness side and the suspect parking aid sensor, harness side as follows:

    • Are the resistances less than 5 ohms? 
      • Yes:  GO to B4.
      • No:  REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
  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:
      Suspect Parking Aid Sensor, Harness Side And Ground

      DTC Rear Sensor Connector-Pin Circuit
      C1700 LH outer C4009-2 VMP15 (YE/GN)
      C1703 RH outer C4011-2 VMP17 (YE/OG)
      C1706 Center C4228-2 VMP14 (WH/OG)

    • Is the resistance greater than 10, 000 ohms? 
      • Yes:  If all of the parking aid sensors recorded DTCs, GO to B5.

        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. TEST the system for normal operation.

      • No:  REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
  5. B5 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.
