Climate Control Unit Inspection [Full-Auto Air Conditioner]

CLIMATE CONTROL UNIT INSPECTION [FULL-AUTO AIR CONDITIONER]

1. Turn the ignition switch to the ON position.

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

3. By inserting the positive (+) lead of the tester into each climate control unit 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 (except for terminal F), replace the climate control unit.
- For terminal F, first try replacing the power MOS FET. If there is still any malfunction, replace the climate control unit.
