Pinpoint Test F: DTC C1279, C1280, C1281, C1282, C1516, C1517, C2769, C2770 - Stability Control Sensor Cluster Fault

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
NOTE: The yaw rate sensor, roll-rate sensor, lateral accelerometer and longitudinal accelerometer are integral to the stability control sensor cluster.
NOTE: Make sure the vehicle is sitting on level ground, at a complete standstill and is not  on a hoist before calibrating the stability control sensor cluster.
NOTE: Make sure the vehicle is sitting on level ground, at a complete standstill and is not  on a hoist before carrying out this pinpoint test. Any vehicle movement will result in false values for this test.
  1. F1 CARRY OUT THE CALIBRATION PROCEDURE 
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: Clear DTCs
    • Carry out the ABS module calibration procedure using the scan tool.
    • Retrieve the DTCs.
    • Are any DTCs retrieved or does the recalibration procedure indicate a fault? 
    1. YES  : Go to  F2.
    2. NO  : The system is operating correctly. The condition may have been caused by an incomplete or inaccurate stability control sensor cluster calibration.
  2. F2 CHECK SENSOR CLUSTER MOUNTING AND MOUNTING SURFACE 
    • Key in OFF position.
    • Inspect the sensor cluster mounting and make sure that the nuts are fully seated and tightened correctly. Inspect the mounting surface for damage, corrosion or dirt.
    • Were the sensor cluster nuts tightened incorrectly or a significant amount of corrosion or dirt found or the mounting surface damaged? 
    1. YES  : CLEAN and TIGHTEN the nuts to correct specification. CLEAN or REPAIR the mounting surface as necessary. CLEAR the DTCs. RECALIBRATE the ABS module. FOLLOW the scan tool directions for the calibration procedure. REPEAT the self-test.
    2. NO  : Go to  F3.
  3. F3 CHECK CIRCUIT CBP35 (YE/GY) FOR VOLTAGE 
    • Disconnect: Stability Control Sensor Cluster C3037
    • Key in ON position.
      • Fig 1: Measuring Voltage Between Sensor Cluster C3037-2, Circuit CBP35 (YE/GY) & Ground

    • Measure the voltage between the sensor cluster C3037-2, circuit CBP35 (YE/GY), harness side and ground.
    • Is the voltage greater than 10 volts? 
    1. YES  : Go to  F4.
    2. NO  : VERIFY SJB fuse 35 (10A) is OK. If OK, REPAIR circuit CBP35 (YE/GY). CLEAR the DTCs. RECALIBRATE the ABS module. FOLLOW the scan tool directions for the calibration procedure. REPEAT the self-test.
  4. F4 CHECK CIRCUIT GD151 (BK/GN) FOR AN OPEN 
    • Key in OFF position.
      • Fig 2: Measuring Resistance Between Sensor Cluster C3037-5, Circuit GD151 (BK/GN) & Ground
      GF0012310Courtesy of FORD MOTOR CO.
    • Measure the resistance between the sensor cluster C3037-5, circuit GD151 (BK/GN), harness side and ground.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  F5.
    2. NO  : REPAIR circuit GD151 (BK/GN). CLEAR the DTCs. RECALIBRATE the ABS module. FOLLOW the scan tool directions for the calibration procedure. REPEAT the self-test.
  5. F5 CHECK CIRCUITS VCA23 (BU/WH) AND VCA24 (GN/OG) FOR AN OPEN 
    • Disconnect: ABS Module C135
      • Fig 3: Measuring Resistance Between ABS Module C135-8 & C135-9, Circuit VCA23 (BU/WH) & VCA24 (GN/OG)
      GF0031560Courtesy of FORD MOTOR CO.
    • Measure the resistance between:
      • ABS module C135-8, circuit VCA23 (BU/WH), harness side and stability control sensor cluster C3037-3, circuit VCA23 (BU/WH), harness side.
      • ABS module C135-9, circuit VCA24 (GN/OG), harness side and stability control sensor cluster C3037-4, circuit VCA24 (GN/OG), harness side.
    • Are the resistances less than 5 ohms? 
    1. YES  : Go to  F6.
    2. NO  : REPAIR the affected circuit(s). CLEAR the DTCs. RECALIBRATE the ABS module. FOLLOW the scan tool directions for the calibration procedure. REPEAT the self-test.
  6. F6 CHECK CIRCUITS VCA23 (BU/WH) AND VCA24 (GN/OG) FOR A SHORT TO GROUND 
      Fig 4: Measuring Resistance Between Ground & Stability Control Sensor Cluster C3037-3 & C3037-4
      GF0031561Courtesy of FORD MOTOR CO.
    • Measure the resistance between ground and:
      • stability control sensor cluster C3037-3, circuit VCA23 (BU/WH), harness side.
      • stability control sensor cluster C3037-4, circuit VCA24 (GN/OG), harness side.
    • Are the resistances greater than 10,000 ohms? 
    1. YES  : Go to  F7.
    2. NO  : REPAIR the affected circuit(s). CLEAR the DTCs. RECALIBRATE the ABS module. FOLLOW the scan tool directions for the calibration procedure. REPEAT the self-test.
  7. F7 CHECK CIRCUITS VCA23 (BU/WH) AND VCA24 (GN/OG) FOR A SHORT TO VOLTAGE
