Heated Seat Element - Diagnosis and Testing

HEATED SEAT ELEMENTS

The wire harness connectors for the heating elements are located under the seat. For circuit descriptions and diagrams, refer to Diagrams/Electrical.

NOTE: When checking heated seat elements for continuity, be certain to move the heating element being checked. Moving the element, such as would occur by sitting in the seat, will check for the possibility of an intermittent open in the element which would only be evident if the element was in a certain position. Failure to check the element in various positions could result in an incomplete test.

FRONT SEAT SYSTEM

1. Locate the memory heated seat adjustable pedal module. Disconnect the appropriate connector from the module. Refer to Diagrams/Electrical for details.
2. Check for continuity between the two wires leading to and out of the appropriate heated seat element. There should be continuity. Less than 6 ohms. If OK, Testing and Inspection for complete system testing procedures. If not OK, install a replacement heated seat element. Memory/Heated Seat Adjustable Pedal Module - Removal Removal.

2ND ROW SEAT SYSTEM

1. Locate the heated seat element connector, located under the seat. Disconnect the appropriate connector. Refer to Diagrams/Electrical for details.
2. Check for continuity between the two wires leading to and out of the appropriate heated seat element. There should be continuity. Less than 6 ohms.
