Seat Heater Switch: Testing and Inspection
Heated Seats
HEATED SEAT SWITCH
In order to obtain conclusive testing, the heated seat system and the Controller Area Network (CAN) data bus circuit must be checked. Any diagnosis of
the heated seat system should begin with, the use of a scan tool and the appropriate diagnostic service information.
Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information.
NOTE: Vehicles equipped with the heated seat option utilize a low voltage cut-off feature. This feature turns off power to the heated seat system
anytime vehicle voltage is below 11.0v or above 15.5v. Be certain to check the vehicle electrical system for proper voltage anytime the power seat
system appears inoperative.
Before any testing of the power seat system is attempted, the battery should be fully-charged.
