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: Control Assembly/Testing and Inspection/Component
Tests and General Diagnostics/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.
