3. Disconnect the 4-way heated seat wire harness connector from the seat cushion frame. Using an ohmmeter, check the resistance between the
heated seat sensor input circuit cavity and the heated seat sensor feed circuit cavity in the 4-way heated seat wire harness connector.
The heated seat sensor resistance should be between 1 kilo ohm and 100 kilo ohms.
If OK, go to Step 4.
If not OK, replace the faulty seat cushion heating element assembly.
4. 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 Diagnosis and Testing the Heated Seat Module for the proper heated seat module diagnosis and testing procedures See: Body and
Frame/Relays and Modules - Body and Frame/Seat Heater Control Module/Testing and Inspection.
If not OK, repair the shorted or open heated seat wire harness as required.
