COOLING FAN
DescriptionINFOID:0000000001162687
Cooling fan operates at each speed when the current flows in the cooling fan motor as follows.
Refer to EC-1097, "
System Description" for cooling fan operation.
Component Function CheckINFOID:0000000001162688
1.CHECK COOLING FAN LOW SPEED FUNCTION
1. Start engine and let it idle.
2. Turn air conditioner switch and blower fan switch ON.
3. Make sure that cooling fan operates at low speed.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Refer to EC-1211, "
Diagnosis Procedure".
2.CHECK COOLING FAN HIGH SPEED FUNCTION
1. Turn ignition switch OFF.
2. Turn air conditioner switch and blower fan switch OFF.
3. Disconnect engine coolant temperature sensor harness connector.
4. Connect 150Ω resistor to engine coolant temperature sensor harness connector.
5. Restart engine and make sure that cooling fan operates at higher speed than low speed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Refer to EC-1211, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001162689
1.CHECK CAN COMMUNICATION LINE
Refer to LAN-33, "
CAN Communication Signal Chart".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace
2.CHECK COOLING FAN RELAY POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector E44.
3. Check the voltage between IPDM E/R harness connectors and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check the following.
 50A fusible link (letter J)
 Harness for open or short between IPDM E/R and battery
>> Repair or replace malfunctioning part.
4.CHECK COOLING FAN CIRCUIT FOR OPEN AND SHORT
1. Disconnect cooling fan motor harness connector.

STOP LAMP SWITCH
STOP LAMP SWITCH
DescriptionINFOID:0000000001162692
Brake switch signal is applied to the ECM through the stop lamp switch when the brake pedal is depressed.
This signal is used mainly to decrease the engine speed when the vehicle is driving.
Component Function CheckINFOID:0000000001162693
1.CHECK BRAKE SWITCH FUNCTION
1. Turn ignition switch ON.
2. Check the voltage between ECM harness connector and ground.
Is the inspection result normal?
YES >> INSPECTION END.
NO >> Go to EC-1214, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001162694
1.CHECK BRAKE SWITCH POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect stop lamp switch harness connector.
3. Turn ignition switch ON.
4. Check the voltage between stop lamp switch harness connector and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.DETECT MALFUNCTIONING PART
Check the following.
 Harness connectors M69, E7 (LHD models)
 Harness connectors M25, M201 (RHD models)
 10A fuse (No. 7)
 Harness for open or short between fuse and stop lamp switch
>> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK BRAKE SWITCH INPUT SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between stop lamp switch harness connector and ECM harness connector.
