  • Malfunctioning seat control module.
  • Grounding issues in the circuit.

Common misdiagnosis for B1960 Seat Recline Forward/Backward Potentiometer Feedback Circuit Short To Battery

  • Faulty seat recline motor
  • Damaged wiring or connectors
  • Malfunctioning body control module (BCM)
  • Incorrectly calibrated seat position sensors
  • Faulty potentiometer
  • Short circuit in the seat harness
  • Issues with the power supply to the seat system

Common Troubleshooting Steps

When dealing with an OBD-II code B1960, which indicates a problem with the seat recline forward/backward potentiometer feedback circuit shorted to battery, you can follow these common troubleshooting steps:

  • Scan Tool Verification: Use an OBD-II scanner to confirm the presence of the B1960 code. Check for any additional codes that may provide more context.
  • Visual Inspection: Inspect the wiring and connectors associated with the seat recline potentiometer. Look for signs of damage, corrosion, or loose connections.
  • Check the seat harness for any fraying or pinching that could cause a short circuit.
  • Check the Potentiometer: Locate the seat recline potentiometer and inspect it for physical damage.
  • Measure the resistance of the potentiometer using a multimeter. Compare the readings to the specifications in the vehicle’s service manual.
  • Test for Short to Battery: With the vehicle off, use a multimeter to check for continuity between the potentiometer signal wire and the battery positive terminal. A reading of zero ohms indicates a short.
  • If a short is found, trace the wiring back to locate the source of the short.
  • Inspect the Seat Control Module: If the wiring and potentiometer are in good condition, check the seat control module for faults. This may involve checking for proper power and ground at the module.
  • If possible, test the module with a known good unit to see if the problem persists.
  • Check for Ground Issues: Ensure that the ground connections for the seat recline system are secure and free of corrosion. A poor ground can cause erratic behavior and false codes.
  • Clear Codes and Test Drive: After performing repairs, clear the trouble codes using the OBD-II scanner.
  • Take the vehicle for a test drive to see if the code returns. Monitor the seat recline function to ensure it operates correctly.
  • Consult Service Manual: If the issue persists, consult the vehicle’s service manual for specific diagnostic procedures related to the seat recline system.
  • Professional Help: If you are unable to resolve the issue, consider seeking assistance from a professional mechanic or an automotive electrician who has experience with electrical systems. By following these steps, you should be able to diagnose and potentially resolve the issue related to the B1960 code.
