Heated Seat Element

The heated seat module will self-diagnose shorted or open heated seat element circuits and sensor circuits. To manually check the heated seat element, proceed as follows. The wire harness connectors for the seat cushion and seat back heating elements and sensor are located on the right side of the seat, near the edge of the seat cushion frame. The proper connector can be identified by the foam wrapping.

NOTE: When checking heated seat elements for continuity, be certain to move the heating element being checked. Moving the element, such as sitting in the seat will eliminate 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.

1. Position the appropriate seat in the full forward position.
2. Make certain the ignition switch is in the OFF position.
3. Disconnect the heated seat element connector which requires testing. Check for continuity between the two heated seat element circuit cavities while moving the appropriate seat cushion. the appropriate wiring information for the location of complete heated seat system wiring diagrams. There should be continuity. If OK, the elements within the seat assembly test OK, go to Step 4. If not OK, replace the inoperative seat heating element.
4. Test the seat wire harness between the heated seat module connector and the appropriate heated seat wire harness connector for shorted or open circuits. If OK, element is OK, proceed with testing the heated seat sensor and module. If not OK, repair the shorted or open seat wire harness as required.
