The OBD2 code B1713 indicates a malfunction in the driver front seat down switch circuit, which may involve a failure in the switch itself, wiring, or the seat control module
Definition
The OBD2 code B1713 indicates a malfunction in the driver front seat down switch circuit, which may involve a failure in the switch itself, wiring, or the seat control module
Common causes
- Faulty driver front seat down switch
- Damaged wiring or connectors in the seat switch circuit
- Short circuit in the seat down switch circuit
- Open circuit in the seat down switch circuit
- Malfunctioning seat control module
- Corrosion or poor connections in the wiring harness
- Faulty power supply to the seat switch
- Issues with the vehicle's body control module (BCM)
Common misdiagnoses
- Faulty seat motor
- Wiring issues or shorts
- Malfunctioning seat control module
- Faulty body control module
- Incorrectly installed or damaged seat assembly
- Issues with the power supply to the seat
- Problems with other seat switch circuits
Troubleshooting steps
-
1. Check for Additional Codes
Use an OBD-II scanner to check for any other related trouble codes. This can provide more context and help identify if there are multiple issues
-
2. Inspect the Seat Switch
-
3. Remove the seat switch from the driver's seat
-
4. Check for any visible damage, corrosion, or loose connections
-
5. Test the switch with a multimeter to ensure it is functioning correctly. You should see continuity when the switch is activated
-
6. Examine Wiring and Connectors
-
7. Inspect the wiring harness and connectors leading to the seat switch and the seat motor for any signs of damage, fraying, or corrosion
-
8. Look for any pinched or broken wires that could interrupt the circuit
-
9. Test the Seat Motor
-
10. If the switch appears to be functioning correctly, test the seat motor itself
-
11. Apply direct power to the motor to see if it operates. If it does not, the motor may be faulty and need replacement
-
12. Check for Ground Issues
-
13. Ensure that the ground connections for the seat motor and switch are secure and free of corrosion. A poor ground can cause circuit failures
-
14. Inspect the Body Control Module (BCM)
-
15. The BCM controls various electrical functions in the vehicle, including the power seat. If all other components check out, the BCM may be malfunctioning
-
16. Check for any software updates or recalls related to the BCM
-
17. Look for Short Circuits
-
18. Use a multimeter to check for short circuits in the wiring. A short can cause the circuit to fail and trigger the B1713 code
-
19. Clear the Code and Test Drive
-
20. After performing the above checks and repairs, clear the trouble code using the OBD-II scanner
-
21. Take the vehicle for a test drive to see if the code reappears
-
22. Consult a Professional
-
23. If the issue persists after performing these steps, it may be best to consult a professional mechanic or an automotive electrician for further diagnosis. By following these steps, you should be able to identify and resolve the issue related to the B1713 code
