What Does B1714 Mean?
This code indicates that the Body Control Module (BCM) has detected an open circuit in the driver's seat front down adjustment switch wiring or component. The BCM monitors the switch input signal and has determined that there is no continuity or electrical connection in the circuit, preventing the seat from moving downward at the front. This is a manufacturer-specific code related to power seat position control systems.
Common Causes
40%
Faulty driver seat front down switch with internal open circuit or broken contacts
30%
Broken, disconnected, or corroded wiring harness connector at the seat switch or seat motor module
20%
Damaged or severed wiring between the seat switch and BCM or seat control module
10%
Failed Body Control Module with internal circuit fault or corrupted programming
Diagnostic Steps
1
Step 1: Perform a thorough visual inspection of the driver seat switch assembly and all visible wiring harness connectors under the seat. Look for disconnected plugs, corroded terminals, damaged wires, or broken switch housing.
2
Step 2: Using a digital multimeter, test for continuity across the front down switch terminals while activating the switch. With the switch pressed, you should see continuity (near 0 ohms); released should show open circuit (infinite resistance). If no continuity when pressed, switch is faulty.
3
Step 3: Disconnect the seat switch harness connector and inspect terminals for corrosion, bent pins, or pushed-back pins. Using a multimeter in resistance mode, check continuity of the wiring from the switch connector to the BCM or seat control module connector (refer to wiring diagram for pin locations). Should read less than 5 ohms.

Step 4: If wiring and switch test good, access the BCM connector and check for voltage supply and ground at the switch circuit terminals with ignition on. Verify BCM is providing proper reference voltage (typically 5V or 12V depending on manufacturer) to the switch circuit.
5
Step 5: After replacing the faulty component (switch, wiring, or connector), clear the DTC code and cycle the seat through all positions multiple times to verify proper operation and confirm the code does not return.

The most common cause of B1714 (Seat Driver Front Down Switch Circuit Open) is: Faulty driver seat front down switch with internal open circuit or broken contacts
Typical repair costs for B1714 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 and it is completely safe to continue driving. The only impact is limited functionality of the driver seat adjustment, specifically the inability to lower the front portion of the seat cushion.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1714 to identify the root cause.
