Pinpoint Test AJ : B2729: Notes
Refer to Climate Controlled Seats for schematic and connector information.
Normal Operation and Fault Conditions
The DCSM monitors seat cushion temperature while it supplies voltage and ground to both blower motors. The DCSM also supplies a variable voltage signal to control the blower speed. Cabin air enters the blower through a filter attached to the blower motor housing. Heated or cooled air exits the blower motor and flows through the foam pad.
