PINPOINT TEST B: DTCs C1700, C1703, C1706 AND C1709 - PARKING AID SENSOR CIRCUIT FAILURE OR BLOCKAGE

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: 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 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  B2 .
    2. NO  : For DTCs C1700, C1703, C1706 or C1709, 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? 
    1. YES  : Go to  B3.
    2. NO  : REPAIR or INSTALL a new bumper wiring harness. CLEAR the DTCs. REPEAT the self-test.
  3. B3 CHECK THE SENSOR CIRCUITRY FOR OPENS 
    • Key in OFF position.
    • Disconnect: Suspect Parking Aid Sensor C4009, C4010, C4011 and C4012
    • Disconnect: PAM C4014
    • Measure the resistance between the PAM C4014, harness side and the suspect parking aid sensor, harness side as follows:
      DTC Rear Sensor PAM Connector- Pin Sensor Connector- Pin Circuit
      C1700 LH outer C4014-9 C4009-1 LMP07 (BU/WH)
      C1700 LH outer C4014-15 C4009-2 VMP15 (YE/GN)
      C1700 LH outer C4014-12 C4009-3 RMP07 (GN/WH)
      C1703 RH outer C4014-9 C4011-1 LMP07 (BU/WH)
      C1703 RH outer C4014-16 C4011-2 VMP17 (YE/OG)
      C1703 RH outer C4014-12 C4011-3 RMP07 (GN/WH)
      C1706 LH inner C4014-9 C4010-1 LMP07 (BU/WH)
      C1706 LH inner C4014-14 C4010-2 VMP14 (WH/OG)
      C1706 LH inner C4014-12 C4010-3 RMP07 (GN/WH)
      C1709 RH inner C4014-9 C4012-1 LMP07 (BU/WH)
      C1709 RH inner C4014-13 C4012-2 VMP16 (YE/GY)
      C1709 RH inner C4014-12 C4012-3 RMP07 (GN/WH)
    • Are the resistances less than 5 ohms? 
    1. YES  : Go to  B4.
    2. 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
      C1700 LH outer C4009-2 VMP15 (YE/GN)
      C1703 RH outer C4011-2 VMP17 (YE/OG)
      C1706 LH inner C4010-2 VMP14 (WH/OG)
      C1709 RH inner C4012-2 VMP16 (YE/GY)
    • Are the resistances greater than 10,000 ohms? 
    1. 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. REPEAT the self-test.

    2. NO  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test.
  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? 
    1. YES  : INSTALL a new PAM. REFER to Parking Aid Module . 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.
