What Does B1713 Mean?
This code indicates that the Body Control Module (BCM) or Seat Control Module has detected an electrical circuit malfunction in the driver's seat front-down adjustment switch. The module has identified either an open circuit, short circuit, or abnormal voltage/resistance reading when the switch is operated or during continuous monitoring. This is a manufacturer-specific code related to the power seat control system.
Common Causes
40%
Faulty driver seat front down switch with internal contact failure or wear
30%
Damaged or corroded wiring harness connector at the seat switch or control module
20%
Broken or chafed wiring in the seat adjustment switch circuit
10%
Failed seat control module or BCM with internal circuit fault
Diagnostic Steps
1
Step 1: Perform visual inspection of the driver seat adjustment switch assembly for physical damage, stuck buttons, or signs of liquid intrusion. Operate the front-down switch multiple times while observing for mechanical binding or abnormal operation.
2
Step 2: Access the driver seat switch connector and inspect for corrosion, bent pins, or moisture. Disconnect the connector and measure resistance across the front-down switch terminals using a digital multimeter while activating the switch (should show 0-5 ohms when pressed, infinite ohms when released).
3
Step 3: Check continuity and resistance of the wiring harness between the seat switch connector and the seat control module/BCM connector. Wiggle the wiring harness under the seat while monitoring for intermittent opens or shorts (should maintain steady continuity below 5 ohms with no fluctuation).
4
Step 4: Using the scan tool, monitor live data for seat switch inputs while operating the front-down switch. Compare the signal status with the physical switch operation to verify proper communication with the control module.
5
Step 5: If all wiring and connections test good, substitute a known-good seat switch assembly to confirm switch failure. If problem persists with new switch, test control module ground circuits and power supply circuits for proper voltage (typically 12V ignition-switched power and solid ground).
6
Step 6: Clear the DTC, perform seat adjustment function test in all directions, and verify the code does not return after multiple switch activation cycles.

The most common cause of B1713 (Seat Driver Front Down Switch Circuit Failure) is: Faulty driver seat front down switch with internal contact failure or wear
Typical repair costs for B1713 range from $75 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This code does not affect vehicle safety or drivability. The vehicle is safe to drive, though the driver's seat front-down adjustment function may be inoperative or work intermittently, causing minor inconvenience.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1713 to identify the root cause.
