Seat Heater Sensor: Testing and Inspection
For complete circuit diagrams, refer to WIRING.
NOTE: ANY RESISTANCE VALUES (OHMS ) GIVEN IN THE FOLLOWING TEXT ARE SUPPLIED USING THE AUTOMATIC RANGE
GENERATED BY A FLUKE AUTOMOTIVE METER. IF ANOTHER TYPE OF MEASURING DEVICE IS USED THE VALUES GENERATED
MAY NOT BE THE SAME AS THE RESULTS SHOWN HERE, OR MAY HAVE TO BE CONVERTED TO THE RANGE USED HERE.
1. Disconnect the heated seat wire harness connector from under the seat. Using an ohmmeter, check the resistance between the heated seat sensor
input circuit cavity and the heated seat sensor feed circuit cavity in the heated seat wire harness connector. The heated seat sensor resistance
should be between 1 kilohm and 100 kilohms. If OK, go to Step 2. If not OK, replace the faulty seat heating element assembly.
2. Test the seat wire harness between the heated seat module connector and the heated seat wire harness connector for a shorted or open circuit. If
OK, refer to Diagnosis and Testing the Heated Seat Module in Electronic Control Modules, for the proper heated seat module diagnosis and
testing procedures If not OK, repair the shorted or open heated seat wire harness as required
