Description

Provides cooling and heat for the seatback.

Component Function Check

1.CHECK SEATBACK THERMAL ELECTRIC DEVICE FUNCTION

  1. Turn the climate controlled seat switch to the H (Heat) HI position and check that the seatback thermal electric device operates correctly.
  2. Turn the climate controlled seat switch to the C (Cool) HI position and check that the seatback thermal electric device operates correctly.

Diagnosis Procedure

Regarding Wiring Diagram information, refer to SE-44, "Wiring Diagram".

1.CHECK SEATBACK THERMAL ELECTRIC DEVICE

Perform thermal electric device component inspection for the seatback. Refer to SE-19, "Component Inspection (Thermal Electric Device)".

2.CHECK SEATBACK THERMAL ELECTRIC DEVICE CIRCUITS

  1. Turn ignition switch OFF.
  2. Disconnect seatback thermal electric device connector and climate controlled seat control unit connector B217.
  3. Check continuity between seatback thermal electric device connector B218 (A) terminals 1, 2 and climate controlled seat control unit connector B217 (B) terminals 25, 28.

 

4. Check continuity between seatback thermal electric device connector B218 (A) terminals 1, 2 and ground.

3.CHECK SEATBACK THERMAL ELECTRIC DEVICE SENSOR CIRCUITS

  1. Disconnect climate controlled seat control unit connector B212.
  2. Check continuity between seatback thermal electric device connector B218 (A) terminals 3, 4 and climate controlled seat control unit connector B212 (B) terminals 15, 16.

 

3. Check continuity between seatback thermal electric device connector B218 (A) terminals 3, 4 and ground.

Component Inspection (Thermal Electric Device)

1.CHECK THERMAL ELECTRIC DEVICE

  1. Turn ignition switch OFF.
  2. Disconnect thermal electric device connector.
  3. 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.
