What Does B1960 Mean?
This code indicates the Body Control Module (BCM) or Seat Control Module has detected a short to battery voltage in the feedback circuit of the seat recline position potentiometer. The potentiometer provides analog voltage feedback to the control module about the seat back angle position, and the system has detected voltage higher than expected, indicating the signal wire is contacting a power source. This prevents proper position monitoring and may disable power seat recline functionality.
Common Causes
45%
Damaged or chafed wiring harness causing short to power in the potentiometer feedback circuit, often at seat track flex points or under seat mounting brackets
30%
Failed seat recline potentiometer with internal short to power source
15%
Corroded or damaged connector terminals at the seat motor assembly or control module allowing cross-contamination between power and signal circuits
10%
Faulty seat control module with internal circuit fault creating false short-to-battery detection
Diagnostic Steps
1
Step 1: Perform visual inspection of seat recline motor assembly and wiring harness, checking for obvious damage, chafing, pinched wires, or burned connections at flex points and mounting brackets
2
Step 2: Disconnect the seat recline potentiometer connector and measure resistance between the feedback signal pin and ground (typically 1-10k ohms varying with position); if open or shorted, replace potentiometer
3
Step 3: With potentiometer disconnected, use a digital multimeter to measure voltage on the feedback signal wire at the harness connector; should read 0V with ignition on - if battery voltage is present, trace and repair short in harness
4
Step 4: Check for voltage drop or resistance between potentiometer ground circuit and chassis ground; should be less than 0.1V or 5 ohms - repair ground circuit if excessive
5
Step 5: Inspect connector terminals for corrosion, bent pins, or moisture intrusion that could cause cross-circuit contamination; clean or replace connectors as needed
6
Step 6: After repairs, clear codes, cycle seat recline function through full range of motion, and verify code does not return and proper position feedback is restored
Estimated Repair Cost
$150 - $650

The most common cause of B1960 (Seat Recline Forward/Backward Potentiometer Feedback Circuit Short To Battery) is: Damaged or chafed wiring harness causing short to power in the potentiometer feedback circuit, often at seat track flex points or under seat mounting brackets
Typical repair costs for B1960 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive as this only affects power seat recline functionality and does not impact vehicle operation or safety systems. The seat may remain in a fixed position or manual adjustment may still be possible depending on seat design. Repair at convenience, though continued operation may cause additional damage to wiring or modules.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1960 to identify the root cause.
