PINPOINT TEST C: DTCs C1699, C1702, C1705 AND C1708 - SENSOR CIRCUIT SHORT TO VBAT

WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. C1 RETRIEVE THE DTCs FROM BOTH THE CONTINUOUS AND ON-DEMAND PAM SELF-TESTS 
    • Check the PAM DTCs from the continuous and on-demand self-tests.
    • Are multiple DTCs recorded? 
    1. YES  : Go to  C2.
    2. NO  : For DTCs C1699, C1702, C1705 or C1708, go to  C3.

      For all other DTCs, REFER to DTC CHARTS .

  2. C2 CHECK THE BUMPER WIRING HARNESS 
    • Inspect the bumper wiring harness for opens, shorts, grounds, or corrosion.
    • Is the bumper wiring harness OK? 
    1. YES  : Go to  C3.
    2. NO  : REPAIR or INSTALL a new bumper wiring harness. CLEAR the DTCs. REPEAT the self-test.
  3. C3 CHECK THE SENSOR CIRCUITRY FOR SHORTS TO VOLTAGE 
    • Key in OFF position.
    • Disconnect: Suspect Parking Aid Sensor C4009, C4010, C4011 or C4012
    • Disconnect: PAM C4014
    • Key in ON position.
    • Measure the voltage between the suspect parking aid sensor, harness side and ground as follows:
      DTC Rear Sensor Connector-Pin Circuit
      C1699 LH outer C4009-2 VMP15 (YE/GN)
      C1702 RH outer C4011-2 VMP17 (YE/OG)
      C1705 LH inner C4010-2 VMP14 (WH/OG)
      C1708 RH inner C4012-2 VMP16 (YE/GY)

    • Is any voltage present? 
    1. YES  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test.
    2. NO  : Go to  C4.
  4. C4 CHECK THE PARKING AID SENSORS 
    • Install a known good parking aid sensor(s) for each of the suspect parking aid sensor(s).
    • Clear the DTCs. Repeat the self-test.
    • Test the system for normal operation.
    • Is the concern still present? 
    1. YES  : If all of the parking aid sensors recorded DTCs, go to  C5.

      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.

    2. NO  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test.
  5. C5 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? 
    1. YES  : INSTALL a new PAM. REFER to PARKING AID MODULE (PAM) . TEST the system for normal operation.
    2. 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.
