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.

Flashing the Headlights
To flash the headlights, pull the lever fully
towards you (the headlight switch does not
need to be on).
The headlight high-beam indicator light
