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.

Confirmation Step 3: Antenna System Simple Inspection [Radio]
Because the antenna system is equipped with a capacitor, the continuity cannot
be checked. Therefore proceed the following simple inspection.
Turn the AM radio on.
Tune to the frequency that there is no broadcast and you will hear a
buzzing sound.
Turn ...
