Code B1956 Description
The B1956 diagnostic trouble code (DTC) indicates a problem with the seat front up/down potentiometer feedback circuit shorting to the battery. This code typically affects vehicles with power adjustable seats, where the position of the seat is controlled electronically. The potentiometer is a sensor that measures the position of the seat and sends feedback to the vehicle's control module. A short circuit to the battery can disrupt this feedback signal, leading to issues with adjusting the seat's position.
Common Causes of B1956
- Damaged wiring or connectors in the seat front up/down potentiometer circuit.
- Faulty seat front up/down potentiometer sensor.
- Short circuit in the wiring harness leading to the battery.
- Corrosion or moisture in the electrical connections.
- Issues with the power seat control module.
Symptoms of B1956
- Inability to adjust the seat position up or down.
- Seat stuck in a fixed position.
- Erratic movement or jerking of the seat when attempting to adjust.
- Warning light on the dashboard related to the power seat system.
How to Fix B1956
- Begin by diagnosing the specific cause of the short circuit, using a multimeter to test the continuity of the wiring and connections.
- Inspect the seat front up/down potentiometer sensor for any signs of damage or malfunction.
- Repair or replace any damaged wiring, connectors, or components in the circuit.
- Clear the DTC from the vehicle's memory using a diagnostic scan tool.
- Test the power seat adjustment system to ensure proper functionality after the repair.
Cost to Fix B1956
The typical repair costs for addressing a B1956 code may range from $150 to $300, depending on the specific cause of the issue and the labor rates in your area.
