Description
Provides inputs to the climate controlled seat control unit for climate controlled seat operation.
Component Function Check
1.CHECK CLIMATE CONTROLLED SEAT SWITCH FUNCTION
Turn the climate controlled seat switch to the H (Heat) LO, MED, and HI positions and the C (Cool) LO, MED, and HI positions. Check that the climate controlled seat operates at low, medium and high heat, and low, medium and high cool.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to SE-44, "Wiring Diagram".
1.CHECK CLIMATE CONTROLLED SEAT SWITCH
Perform climate controlled seat switch component inspection. Refer to SE-21, "Component Inspection (Climate Controlled Seat Switch)".
