What is B1971 Passenger Seatback Rearward Switch Circuit Short to Ground?

B1971 is a diagnostic trouble code (DTC) that indicates a problem with the passenger seatback rearward switch circuit short to ground. This means that there is a short circuit in the wiring that connects the switch to the car’s electrical system. This can cause the switch to malfunction, making it difficult or impossible to adjust the passenger seatback.

Diagnosing the Problem

The first step in diagnosing the problem is to check the fuse for the passenger seatback rearward switch. If the fuse is blown, replace it and see if the problem is resolved. If the fuse is not the issue, you’ll need to check the wiring for the switch.

To do this, you’ll need a multimeter. Set the multimeter to measure resistance and connect the leads to the switch’s wiring. If the multimeter reads zero resistance, there is a short circuit in the wiring. If the multimeter reads infinite resistance, the wiring is open and needs to be repaired.

Solving the Problem

If the wiring is shorted, you’ll need to locate the short circuit and repair it. This can be a time-consuming process, but it’s essential to fix the problem. Start by inspecting the wiring for any visible damage or wear. If you find any damaged wires, repair or replace them.

If the wiring looks fine, you’ll need to use a wiring diagram to trace the circuit and locate the short. This can be a challenging task, but it’s essential to fix the problem. Once you’ve located the short, repair or replace the damaged wiring.

Useful Tips
