What Does B1767 Mean?
This code indicates that the Body Control Module (BCM) has detected a short to battery voltage in the driver's seat forward adjustment motor circuit. This means the circuit is receiving unwanted voltage, typically from a damaged wire touching a power source, causing the motor to receive constant power when it shouldn't. The BCM monitors this circuit for proper voltage levels and sets this code when it detects voltage present when the switch is not activated.
Common Causes
45%
Damaged or chafed wiring harness under the driver's seat causing wire insulation to expose copper and contact battery voltage source
30%
Failed seat forward/aft switch with internal short circuit providing constant battery voltage to motor circuit
15%
Faulty seat motor with internal short to power creating feedback voltage in control circuit
10%
Water damage or corrosion in seat control module or connector causing cross-circuit short to battery voltage
Diagnostic Steps
1
Step 1: Perform visual inspection under driver's seat for obvious wiring damage, chafing against seat tracks, or pinched harnesses. Check for any signs of previous repairs, water intrusion, or connector corrosion at seat motor and switch connectors.
2
Step 2: Disconnect the driver's seat forward motor connector and check if code clears or returns. Use multimeter to measure voltage at the motor connector with ignition on and switch inactive - should read 0V. If battery voltage present, fault is upstream in wiring or switch.
3
Step 3: Disconnect the seat adjustment switch connector and measure resistance through the forward circuit. With switch not activated, resistance should be open/infinite. If continuity to battery voltage exists, switch is internally shorted and requires replacement.
4
Step 4: With both motor and switch disconnected, check the wiring harness between BCM and seat components using multimeter. Measure for short to battery voltage along the circuit - flex and manipulate wiring under seat while monitoring for intermittent shorts.
5
Step 5: If no wiring faults found, reconnect components one at a time while monitoring voltage. When fault returns, the last connected component is the faulty part. Replace identified component and verify proper operation through full range of seat travel.
6
Step 6: Clear codes, perform seat function test in all directions, and road test vehicle. Re-scan for codes to confirm repair was successful and no other seat circuit faults are present.

The most common cause of B1767 (Seat Driver Forward Circuit Short To Battery) is: Damaged or chafed wiring harness under the driver's seat causing wire insulation to expose copper and contact battery voltage source
Typical repair costs for B1767 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving as this does not affect vehicle operation or safety systems. The driver's seat may move forward unexpectedly or the forward adjustment may not function properly, which could be a minor inconvenience but does not present an immediate safety hazard. Repair at earliest convenience to restore full seat functionality.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1767 to identify the root cause.
