Seat Temperature Sensor: Testing and Inspection

For complete circuit diagrams, refer to Wiring Diagrams.
1. Disconnect and isolate the battery negative cable. Disconnect the green 4-way heated seat module wire harness connector.
2. Using an ohmmeter, check the resistance between cavities 2 and 3. The sensor resistance should be between 2 kilohms at 15 °C (60 °F) and 50 kilohms at 30 °C (85 °F). If not OK, replace the faulty seat element and sensor assembly.
