- Turn A/C switch and blower fan switch ON.
- Check the voltage between ECM harness connector terminals.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-465, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY
- Turn ignition OFF.
- Disconnect refrigerant pressure sensor harness connector.
- Turn ignition switch ON.
- Check the voltage between refrigerant pressure sensor harness connector and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between refrigerant pressure sensor harness connector and ECM harness connector.
- Also check harness for short to ground.
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK REFRIGERANT PRESSURE SENSOR GROUND
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between refrigerant pressure sensor harness connector and ECM harness connector.
- Also check harness for short to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK REFRIGERANT PRESSURE SENSOR INPUT SIGNAL CIRCUIT
- Check the continuity between ECM harness connector and refrigerant pressure sensor harness connector.
- Also check harness for short to ground and to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK INTERMITTENT INCIDENT

Driving on snow or ice
WARNING
Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.
