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, 1E and 2J

4. Verify that below graph as measure the terminal voltage 2J.

5. Follow the climate control unit inspection when measure the other terminal voltage. Full-Auto Air Conditioner

- Terminal 1E: 1.0 V or less
- Terminal 1C: Approx. 5 V (Ignition switch on)

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