- Check the heated seat element (Refer to ELECTRICAL/HEATED SEATS/HEATED SEAT ELEMENT - DIAGNOSIS AND TESTING) .
- Check the heated seat sensor (Refer to ELECTRICAL/HEATED SEATS/HEATED SEAT SENSOR - DIAGNOSIS AND TESTING) .
- Using a voltmeter, back probe the appropriate heated seat module connector, do not disconnect. Check for battery voltage at the appropriate pin cavities. If OK go to step 4. If not OK, repair the open or shorted voltage supply circuit as required.
- Using a ohmmeter, back probe the appropriate heated seat module connector, do not disconnect. Check for proper continuity to ground on the ground pin cavities. Continuity should be present. If OK replace the heated seat module. If Not OK, repair the open or shorted ground circuit as required.
