STEP
INSPECTION
ACTION
1*
INSPECT TO SEE WHETHER MALFUNCTION
(LACK OF CONTINUITY) IS IN AIR INTAKE
ACTUATOR, WIRING HARNESS (BETWEEN
CLIMATE CONTROL UNIT AND AIR INTAKE
ACTUATOR) OR ELSEWHERE
•
Turn ignition switch to ON position.
•
Test voltages at the following terminals of
climate control unit.
— Terminal 2K (12-pin, FRESH motor drive
signal)
— Terminal 2I (12-pin, RECIRCULATE
motor drive signal)
(See

•
Are voltages okay?
Yes
Go to next step.
No
Go to Step 3.
2*
INSPECT TO SEE WHETHER MALFUNCTION
(LACK OF CONTINUITY) IS IN AIR INTAKE
ACTUATOR OR WIRING HARNESS
(BETWEEN CLIMATE CONTROL UNIT AND
AIR INTAKE ACTUATOR)
•
Test voltages at the following terminals of air
intake actuator.
— Terminal D (FRESH motor drive signal)
— Terminal F (RECIRCULATE motor drive
signal)
•
Are voltages as shown below?
— Terminal D:
approximately 0.5 V
during
RECIRCULATE and
approximately 10 V
during FRESH
— Terminal F:
approximately 10 V
during
RECIRCULATE and
approximately 0.5 V
during FRESH
Yes
Replace air intake actuator, then go to Step 8.
