Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR AN ACTIVE DTC 
    1. Turn the ignition on.
    2. With the scan tool, record and erase DTCs.
    3. Cycle the ignition switch from off to on.
    4. With the scan tool, read DTCs.

      Is the DTC active?

      Yes 

      • Go To  2

      No 

      • The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.
      • Perform the ABS INTERMITTENT CONDITION TEST. Refer to ABS INTERMITTENT CONDITION  .
  2. CHECK CONNECTOR/TERMINAL FOR DAMAGE 
    NOTE:

    Check all terminals for broken, bent, pushed out, or corroded terminals.

    1. Turn the ignition off.
    2. Inspect the Wheel Speed Sensor harness and connector.
    3. Inspect the Wheel Speed Sensor for excessive debris on the sensor.

      Were any problems found?

      Yes 

      • Repair as necessary in accordance with the Service Information.
      • Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST  .

      No 

      • Go To  3
  3. CHECK (B9) LEFT FRONT WHEEL SPEED SENSOR SUPPLY CIRCUIT VOLTAGE 
    1. Disconnect the Left Front Wheel Speed Sensor harness connector.
    2. Turn the ignition on.
    3. Measure the voltage between the (B9) Left Front Wheel Speed Sensor Supply circuit and ground.

      Is the voltage above 10 volts?

      Yes 

      • Go To  6

      No 

      • Go To  4
  4. (B9) LEFT FRONT WHEEL SPEED SENSOR SUPPLY CIRCUIT SHORTED TO GROUND 
    1. Turn the ignition off.
    2. Disconnect the ABS Module harness connector.
    3. Measure the resistance between the (B9) Left Front Wheel Speed Sensor Supply circuit and ground.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Repair the (B9) Left Front Wheel Speed Sensor Supply circuit for a short to ground.
      • Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST  .

      No 

      • Go To  5
  5. (B9) LEFT FRONT WHEEL SPEED SENSOR SUPPLY CIRCUIT OPEN 
    1. Measure the resistance of the (B9) Left Front Wheel Speed Sensor Supply circuit between the Left Front Wheel Speed Sensor harness connector and the ABS Module harness connector.

      Is the resistance below 5 Ohms?

      Yes 

      • Go To  6

      No 

      • Repair the open (B9) Left Front Wheel Speed Sensor Supply circuit.
      • Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST  .
  6. (B8) LEFT FRONT WHEEL SPEED SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE 
    1. Turn the ignition on.
    2. Measure the voltage of the (B8) Left Front Wheel Speed Sensor Signal circuit at the Left Front Wheel Speed Sensor harness connector.

      Is there any voltage present?

      Yes 

      • Repair the (B8) Left Front Wheel Speed Sensor Signal circuit for a short to voltage.
      • Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST  .

      No 

      • Go To  7
  7. (B8) LEFT FRONT WHEEL SPEED SENSOR SIGNAL CIRCUIT SHORTED TO GROUND 
    1. Turn the ignition off.
    2. Measure the resistance between the (B8) Left Front Wheel Speed Sensor Signal circuit and ground.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Repair the (B8) Left Front Wheel Speed Sensor Signal circuit for a short to ground.
      • Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST  .

      No 

      • Go To  8
  8. (B8) LEFT FRONT WHEEL SPEED SENSOR SIGNAL CIRCUIT OPEN 
    1. Measure the resistance of the (B8) Left Front Wheel Speed Sensor Signal circuit between the Left Front Wheel Speed Sensor harness connector and the ABS Module harness connector.

      Is the resistance below 5 Ohms?

      Yes 

      • Go To  9

      No 

      • Repair the open (B8) Left Front Wheel Speed Sensor Signal circuit.
      • Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST  .
  9. (B9) LEFT FRONT WHEEL SPEED SENSOR SUPPLY CIRCUIT SHORTED TO THE (B8) LEFT FRONT WHEEL SPEED SENSOR SIGNAL CIRCUIT 
    1. Turn the ignition off.
    2. Measure the resistance between the (B9) Left Front Wheel Speed Sensor Supply circuit and the (B8) Left Front Wheel Speed Sensor Signal circuit at the ABS Module harness connector.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Repair (B9) Left Front Wheel Speed Sensor Supply circuit for a short to the (B8) Left Front Wheel Speed Sensor Signal circuit.
      • Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST  .

      No 

      • Go To  10
  10. LEFT FRONT WHEEL SPEED SENSOR 
    1. Replace the Left Front Wheel Speed Sensor in accordance with the Service Information. Refer to SENSOR, WHEEL SPEED, FRONT, REMOVAL .
