Nissan Maxima Service and Repair Manual / Body interior / Seat / DTC/circuit diagnosis / Seat cushion thermal electric device

Description

Provides cooling and heat for the seat cushion.

Component Function Check

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.

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

  1. Turn ignition switch OFF.
  2. Disconnect seat cushion thermal electric device connector and climate controlled seat control unit connector B217.
  3. 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

  1. Disconnect climate controlled seat control unit connector B212.
  2. 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

  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.
