MZR 2.0, 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.
-
1G,1H 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 1G: 1.0 V or less
-
Terminal 1H: 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.
