Description
Provides cooling and heat for the seat cushion.
Component Function Check
1.CHECK SEAT CUSHION THERMAL ELECTRIC DEVICE FUNCTION
- Turn the climate controlled seat switch to the H (Heat) HI position and check that the seat cushion thermal electric device operates correctly.
- Turn the climate controlled seat switch to the C (Cool) HI position and check that the seat cushion thermal electric device operates correctly.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to SE-44, "Wiring Diagram".
1.CHECK SEAT CUSHION THERMAL ELECTRIC DEVICE
Perform thermal electric device component inspection for the seat cushion. Refer to SE-16, "Component Inspection (Thermal Electric Device)".
2.CHECK SEAT CUSHION THERMAL ELECTRIC DEVICE CIRCUITS
- Turn ignition switch OFF.
- Disconnect seat cushion thermal electric device connector and climate controlled seat control unit connector B217.
- Check continuity between seat cushion thermal electric device connector B219 (A) terminals 1, 2 and climate controlled seat control unit connector B217 (B) terminals 26, 27.
4. Check continuity between seat cushion thermal electric device connector B219 (A) terminals 1, 2 and ground.
3.CHECK SEAT CUSHION THERMAL ELECTRIC DEVICE SENSOR CIRCUITS
- Disconnect climate controlled seat control unit connector B212.
- Check continuity between seat cushion thermal electric device connector B219 (A) terminals 3, 4 and climate controlled seat control unit connector B212 (B) terminals 13, 14.
3. Check continuity between seat cushion thermal electric device connector B219 (A) terminals 3, 4 and ground.
Component Inspection (Thermal Electric Device)
1.CHECK THERMAL ELECTRIC DEVICE
- Turn ignition switch OFF.
- Disconnect thermal electric device connector.
- Measure the resistance of the thermal electric device between terminals 1 and 2.
NOTE:
The resistance value in the table below will change under any of the following conditions:
- air blowing across the thermal electric device
- changing the surrounding temperature of the thermal electric device
- measuring at other than 23C (73F)
2.CHECK THERMAL ELECTRIC DEVICE SENSOR
Measure the resistance of the thermal electric device sensor between terminals 3 and 4.
