Description

INFOID:0000000010049469

Provides cooling and heat for the seat cushion.

Component Function Check

INFOID:0000000010049470

1.

CHECK SEAT CUSHION THERMAL ELECTRIC DEVICE FUNCTION

1. Turn the climate controlled seat switch to the H (Heat) HI position and check that the seat cushion thermal

electric device operates correctly.

2. Turn the climate controlled seat switch to the C (Cool) HI position and check that the seat cushion thermal

electric device operates correctly.

Is the inspection result normal?

YES

>> Seat cushion thermal electric device is OK.

NO

>> Refer to

SE-15, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000010049471

Regarding Wiring Diagram information, refer to
