Seat Heater Sensor: Testing and Inspection
The heated seat module will self-diagnose shorted or open heated seat element circuits and the sensor circuits. Refer to Heated Seat System for the
location of the proper heated seat system diagnosis and testing procedures. To manually check the heated seat element and sensor circuits, proceed as
follows. The wire harness connectors for the seat cushion heated seat element and sensor and for the seat back heated seat element are located under the
seat, near the rear edge of the seat cushion frame.
1. Disconnect and isolate the battery negative cable. Disconnect the 4-way heated seat wire harness connector. Using an ohmmeter, check the
resistance between the heated seat sensor input circuit cavity and the heated seat sensor feed circuit cavity in the seat cushion cover half of the
4-way heated seat wire harness connector. The heated seat sensor resistance should be between 1 kiloohm and 200 kilohms. If OK, go to Step 2.
If not OK, replace the faulty seat cushion trim cover unit.
2. Test the seat wire harness between the heated seat module connector and the 4-way heated seat wire harness connector for shorted or open circuits.
If OK, refer to Heated Seat Module in Electronic Control Modules for the location of the proper heated seat module diagnosis and testing
procedures. Also refer to the Body Diagnostic for additional diagnosis and testing procedures. If not OK, repair the shorted or open heated seat
wire harness as required.
