POWER SUPPLY AND GROUND CIRCUIT FOR FRONT AIR CONTROL
POWER SUPPLY AND GROUND CIRC
UIT FOR FRONT AIR CONTROL
DescriptionINFOID:0000000009463219
COMPONENT DESCRIPTION
Front air control.
The front air control has a built-in microcomputer that processes inform ation sent from various sensors
needed for air conditioner operation. The air mix door motor, the mode door motor, the intake door motor, the
blower motor and the A/C compressor are then controlled.
Component Function CheckINFOID:0000000009463220
1.CHECK OPERATION
1. Turn the blower motor dial clockwise and verify t he blower speed increases and that one of the LEDs illu-
minates on the mode switch.
2. Press the mode switches and verify that the modes change, the LEDs illuminate, and that air flows from
the various vents.
3. Turn the temperature control dial and verify the temperature changes at the selected vents.
4. Press the DEF and REC buttons and verify air flow changes.
Does it operate normally?
YES >> Inspection End.
NO >> Perform trouble diagnosis for the front air control system. Refer to HAC-152, "Diagnosis Proce-
dure".
Diagnosis ProcedureINFOID:0000000009463221
Regarding Wiring Diagram information, refer to HAC-130, "Wiring Diagram".
1.CHECK FRONT AIR CONTROL POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect the front air control connector.
3. Turn ignition switch ON.
4. Check voltage between front air control har ness connector M37 terminals 1, 2 and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK FUSE
Check fuses [Nos. 14 and 30, located in the fuse block (J/B)].
NOTE:
Refer to PG-70, "Terminal Arrangement"
.
Is the inspection result normal?
YES >> Check harness for open circuit. Repair or replace if necessary.
NO >> Check harness for short circuit. Repair or replace if necessary.
