2023 Dodge and Ram Durango R/T Plus, AWDSECTION Diagnostic Test
WARNING: This page is about a different variant/trim than selected.
  1. CHECK FOR AN ACTIVE DTC 
    1. Turn the ignition on.
    2. With the scan tool, read DTCs and record on the repair order.

      Is the DTC active or pending?

      Yes 

      • Go To  2

      No 

  2. CHECK FOR OTHER DTCS 
    1. Refer to the recorded DTCs.

      Are there any 5-Volt Reference DTCs present?

      Yes 

      No 

      • Go To  3
  3. CHECK THE (B237) 5-VOLT SUPPLY CIRCUIT FOR PROPER VOLTAGE AT THE BPP SENSOR HARNESS CONNECTOR 
    1. Turn the ignition on.
    2. Disconnect the BPP Sensor harness connector.
    3. Measure the voltage on the (B237) 5-Volt Supply circuit at the BPP Sensor harness connector.
      NOTE:

      Normal operating voltage should be between 4.8 and 5.2 volts.

      Is the voltage between 4.8 and 5.2 volts?

      Yes 

      • Go To  4

      No 

      • Repair the (B237) 5-Volt Supply circuit for an open or short to ground.
      • Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST .
  4. CHECK THE BPP SENSOR (B138) POSITION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE 
    1. Measure the voltage on the BPP Sensor (B138) Position Signal circuit at the BPP Sensor harness connector.

      Is the voltage reading above 5.2 volts?

      Yes 

      • Repair the BPP Sensor (B138) Position Signal circuit for a short to voltage.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  5
  5. CHECK FOR THE BPP SENSOR (B138) POSITION SIGNAL CIRCUIT SHORTED TO THE (B237) BPP SENSOR 5-VOLT SUPPLY CIRCUIT 
    1. Turn the ignition off.
    2. Disconnect the ABS harness connector.
    3. Check for continuity between the BPP Sensor (B138) Position Signal circuit and the (B237) 5-Volt Supply circuit at the BPP Sensor harness connector.

      Is there continuity between the BPP Sensor (B138) Position Signal circuit and the (B237) 5-Volt Supply circuit?

      Yes 

      • Repair the short between the BPP Sensor (B138) Position Signal circuit and the (B237) 5-Volt Supply circuit.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  6
  6. CHECK THE (B937) SENSOR GROUND CIRCUIT FOR AN OPEN/HIGH RESISTANCE 
    1. Measure the resistance of the (B937) Sensor Ground circuit between the Brake Pedal Sensor harness connector and the ABS harness connector.

      Is the resistance below 3.0 Ohms?

      Yes 

      • Go To  7

      No 

      • Repair the (B937) BPP Ground circuit for an open or high resistance.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  7. VERIFY THE ABILITY OF THE ABS MODULE TO READ THE BPP SENSOR SIGNAL 
    1. Turn the ignition off.
    2. Reconnect the ABS harness connector.
    3. Connect a jumper between the BPP Sensor (B138) Position Signal circuit and the (B937) Sensor Ground circuit at the Brake Pedal Sensor harness connector.
    4. Turn the ignition on.
    5. With the scan tool, read DTCs.
      NOTE:

      The scan tool should display the P057C-BRAKE PEDAL SENSOR SIGNAL CIRCUIT LOW DTC as active or pending with the jumper in place.

      Does the scan tool display the voltage as described above?

      Yes 

      • Verify that there is good pin to terminal contact in the BPP Sensor and ABS Control Module connectors. Replace the BPP Sensor if no problems were found with the connectors.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Remove the jumper.
      • Go To  8
  8. CHECK THE ANTI-LOCK BRAKE MODULE FOR BRAKE PEDAL SENSOR FAULTS 
    1. With the scan tool, read DTCs in the ABS Module.

      Is the ABS Module setting any DTCs against a Brake Pedal Sensor?

      Yes 

      No

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
