Pinpoint Test E: DTCS C1701, C1704, C1707 And C1710 Parking Aid Sensor Fault

WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. E1 RETRIEVE THE RECORDED DTCS FROM BOTH THE CONTINUOUS AND ON-DEMAND PARKING AID MODULE SELF-TESTS 
    • Retrieve the recorded parking aid module DTCs from the continuous and on-demand self-tests.
    • Are multiple DTCs recorded? 
    1. Yes  : GO to E2.
    2. No  : GO to  E3.
  2. E2 CHECK THE BUMPER WIRING HARNESS 
    • Inspect the bumper wiring harness for opens, shorts, grounds, or corrosion.
    • Is the bumper harness OK? 
    1. Yes  : GO to E3.
    2. No  : REPAIR or INSTALL a new bumper wiring harness. REPEAT the self-test.
  3. E3 DETERMINE THE CONDITION 
    NOTE: Make sure the area around the vehicle is clear of anything that may activate the parking aid system.
    • Apply the parking brake.
    • With the brake pedal applied, shift the transmission into REVERSE.
    • Does the parking aid sound a continuous or intermittent tone when no obstacles are present? 
    1. Yes  : GO to  E6.
    2. No  : GO to E4.
  4. E4 MONITOR THE PARKING AID PID 
    NOTE: Make sure the area around the vehicle is clear of anything that may activate the parking aid system.
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: Parking Aid PID.
    • With the brake pedal pressed, shift the transmission into REVERSE and monitor the parking aid sensor distance PID. The PIDs will read 255 cm (100 in) on a correctly functioning sensor.
    • Does the PID read 255 cm (100 in)? 
    1. Yes  : GO to E5.
    2. No  : GO to  E6.
  5. E5 VERIFY THE SUSPECTED SENSOR ALIGNMENT 
    • Make sure the suspect parking aid sensor is the correct sensor.
    • Make sure the suspect parking aid sensor is flush-mounted in the bezel.
    • Make sure the suspect parking aid sensor is in alignment. Align the sensor if necessary. Refer to both the AZIMUTH SYSTEM CHECK  and ELEVATION SYSTEM CHECK .
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: Parking Aid PID.
    • With the brake pedal applied, shift the transmission into REVERSE and monitor the parking aid sensor distance PID. The PID will read 255 cm (100 in) on a correctly functioning sensor.
    • Does the PID read 255 cm (100 in)? 
    1. Yes  : The system is operating normally at this time. CLEAR the DTCs. REPEAT the self-test.
    2. No  : GO to E6.
  6. E6 CHECK THE BUMPER FOR DEBRIS 
    NOTE: Make sure the area around the vehicle is clear of anything that might activate the parking aid system.
    • Clean the rear bumper and sensors with high-pressure water.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. Yes  : GO to E7.
    2. No  : The system is operating correctly at this time. The concern may have been caused by a dirty or blocked parking aid sensor. CLEAR the DTCs. REPEAT the self-test.
  7. E7 CHECK THE PARKING AID SENSOR OPERATION 
    • Move the vehicle to an open area, free of obstacles.
    • Key in ON position.
    • Check the parking aid sensor distance and attenuation PIDs.
    • Do the parking aid sensor distance PIDs read 255 cm (100 in), and the attenuation PIDs read between 0 and 16? 
    1. Yes  : GO to E8.
    2. No  : INSTALL a new parking aid sensor. REFER to PARKING AID SENSOR . CLEAR the DTCs. REPEAT the self-test.
  8. E8 CHECK FOR CORRECT PARKING AID MODULE OPERATION 
    • Disconnect the parking aid module connector.
    • Check for:
      • corrosion
      • pushed-out pins
    • Connect the parking aid module 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 parking aid module. REFER to PARKING AID MODULE . REPEAT the self-test. CARRY OUT the diagnostic tool data link test.
    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.
