1.Install the manifold gauge.

2.Verify the high-pressure side reading of the manifold gauge.

3.Measure the terminal voltage of the climate control unit.

― 1C, 1J and 1N

4.Verify that below graph as measure the terminal voltage 1N.

5.Follow the climate control unit inspection when measure the other terminal voltage. (See CLIMATE CONTROL UNIT INSPECTION [FULL-AUTO AIR CONDITIONER].)

• Terminal 1C: 1.0 V or less

• Terminal 1J: Approx. 5 V (Ignition switch on)

― If the each voltage is not normal, inspect the related wiring harness.

• If there is any malfunction, replace the related wiring harness.

• If wiring harness is normal, replace the refrigerant pressure sensor.
