MZR 2.3 DISI Turbo, MZR 2.5

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..

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.

If there is any malfunction, replace the related wiring harness.
If wiring harness is normal, replace the refrigerant pressure sensor.
