Diagnosis And Testing - Heated Seat Element
NOTE:
For a complete wiring diagram, refer to SYSTEM WIRING DIAGRAMS . Wiring Information includes wiring diagrams, connector pin-out, and location views, details of wire harness routing and retention, splice and ground locations.
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 or short in the element which would only be evident if the element was in a certain position. Actual seat position can cause the wiring to stretch, pinch or short. Also not the proper routing of the wiring harness.
- Locate and disconnect the seat heating element electrical connectors as necessary.
- Check the resistance between the circuits leading in and out of the suspect heated seat element. The resistance should be between the specifications listed in the following Heated Seat Element Resistance chart. If OK, refer to DIAGNOSIS AND TESTING . If not OK, replace the inoperative heated seat element. Refer to PAD, HEATER, REMOVAL .
HEATED SEAT ELEMENT RESISTANCE
| Element Location | Acceptable Resistance Value |
|---|---|
| Driver Seat Bottom Cushion | 7.8 - 9.6 ohms |
| Passenger Seat Bottom Cushion | 8.4 - 10.4 ohms |
| Driver and Passenger Seat Back Cushion | 8.5 - 10.6 ohms |
