Hi and thanks for using 2CarPros.com.

Most commonly, the problem is related to the pressure sensor under the seat. Follow these simple steps to confirm there is not a problem with the connector.

Here is a link that will help when checking the connector and wiring:

Here are the directions for checking the connector and switch.

Faulty signal. Permanent fault

Checking components and wiring
- Ignition off
- Disconnect the battery negative terminal
- Disconnect the seat connector
- Check the connector for contact resistance and oxidation. See Checking wiring and terminals. Permanent fault See: Computers and Control Systems > Component Tests and General Diagnostics > Checking Wiring And Terminals. Permanent Fault
- If the seat connector is defective it must be replaced

If the connection is in good condition, the next steps require special tooling. I can provide them if needed.

I hope this helps. Let me know if you have other questions.

Take care,
Joe
