HEATED SEAT MODULE
1. Test the appropriate heated seat element.

2. Test the appropriate heated seat switch.

3. Using a voltmeter, backprobe the heated seat module connector, do not disconnect. Check for voltage at the appropriate pin cavities. 12v should be present. If OK go to STEP 4, if Not, repair the open or shorted voltage supply circuit as required.

4. Using a ohmmeter, backprobe 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 test the Cabin compartment Node (CCN) cluster using a scan tool for proper heated seat system function. If Not OK, Repair the open or shorted ground circuit as required.
