Description
Provides inputs to the climate controlled seat control unit for climate controlled seat operation.
Component Function Check
1.CHECK CLIMATE CONTROLLED SEAT SWITCH FUNCTION
Turn the climate controlled seat switch to the H (Heat) LO, MED, and HI positions and the C (Cool) LO, MED, and HI positions. Check that the climate controlled seat operates at low, medium and high heat, and low, medium and high cool.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to SE-44, "Wiring Diagram".
1.CHECK CLIMATE CONTROLLED SEAT SWITCH
Perform climate controlled seat switch component inspection. Refer to SE-21, "Component Inspection (Climate Controlled Seat Switch)".
2.CHECK CLIMATE CONTROLLED SEAT SWITCH POWER SUPPLY CIRCUIT


4. Check continuity between climate controlled seat switch connector M302 (A) terminal 1 and ground.

3.CHECK CLIMATE CONTROLLED SEAT SWITCH COOL CIRCUIT


3. Check continuity between climate controlled seat switch connector M302 (A) terminal 2 and ground.

4.CHECK CLIMATE CONTROLLED SEAT SWITCH HEAT CIRCUIT
1. Check continuity between climate controlled seat switch connector M302 (A) terminal 3 and climate controlled seat control unit connector B212 (B) terminal 1.


2. Check continuity between climate controlled seat switch connector M302 (A) terminal 3 and ground.

P0117, P0118 ECT sensor
Description
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the c ...
