Front Power Metal Oxide Semiconductor Field Effect Transistor (Power MOS FET) Inspection [Full-Auto Air Conditioner]

FRONT POWER METAL OXIDE SEMICONDUCTOR FIELD EFFECT TRANSISTOR (POWER MOS FET) INSPECTION [FULL-AUTO AIR CONDITIONER]

1. Remove the front power MOS FET. Front Power Metal Oxide Semiconductor Field Effect Transistor (Power MOS FET) Removal/Installation [Full-Auto Air Conditioner]

2. Connect the front power MOS FET connector.

3. Connect the negative (-) lead of the tester to body ground.

4. Switch the ignition to ON.

5. By inserting the positive (+) lead of the tester into each front power MOS FET terminal, measure the voltage according to the terminal voltage table.

- If there is any malfunction, inspect the parts under "Inspection item (s)".

- If the parts under "Inspection item (s)" are found to be normal, replace the front power MOS FET.
