Seat Heater Control Module: Testing and Inspection
DIAGNOSIS AND TESTING - HEATED SEAT MODULE
One heated seat module is located under each front seat. The drivers side module controls the drivers heated seat and the passenger controls the
passenger heated seat. The first step in the testing procedure is to locate the suspect module and unsnap it from the appropriate seat cushion pan. After
the module is visible, disconnect the modules electrical connector. Perform the following tests, Refer to Wiring for the location of complete heated
seat system wiring diagrams.
1. Check for 12 volts at the Fused B+ terminal of the heated seat control module electrical connector. If OK go to Step 2. If not OK, check the heated
seat cut-out relay, located in the Power Distribution Center.
2. Turn the ignition switch "ON" and check for 12 volts at the switched ignition feed terminal of the heated seat control module electrical connector.
If OK go to Step 3. If not OK, check the ignition feed circuit for shorts or opens.
3. Check for continuity between a known good ground and the ground wire terminal of the heated seat control module electrical connector. If OK go
to step 4. If not OK, carefully inspect the harness for an open or short.
4. Check the heated seat switch input terminal of the heated seat control module electrical connector for the proper MUX signal (resistance range of
0-500 ohms, refer to the heated seat switch diagnosis and testing). If OK replace the heated seat module. If not OK, test the heated seat switch and
harness.
