Component Function Check
1.CHECK SEATBACK THERMAL ELECTRIC DEVICE FUNCTION
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
4. Check continuity between seatback thermal electric device connector B218 (A) terminals 1, 2 and ground.
3.CHECK SEATBACK THERMAL ELECTRIC DEVICE SENSOR CIRCUITS
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
NOTE:
2.CHECK THERMAL ELECTRIC DEVICE SENSOR
Measure the resistance of the thermal electric device sensor between terminals 3 and 4.
Checking engine coolant level
Check the coolant level in the reservoir when
the engine is cold. If the coolant level is below
the MIN level B , add coolant to the MAX level
A . If the reservoir is empty, check the coolant
level in the radiator when the engine is cold. If
there is insufficient coolant in the radiator, fi ...
