Diagnostic Fault Information
Circuit/System Description
The driver and front passenger heated seats are controlled by separate heated seat switches. When a heated seat switch is pressed, ground is momentarily
applied through the switch contacts and the switch signal circuit to the door module. In response to this signal, the door module sends serial data a
message to the memory seat module (MSM) indicating the heat seat request. The door module then applies voltage through the appropriate indicator
control circuits to the heated seat switch illuminating the indicators.
