Component Inspection

■ Check Intake actuator

Ignition "OFF"

Disconnect Intake actuator and A/C control module main harness connector.

Connect (+) terminal of battery to FRE(+) of intake actuator and (-) terminal to REC(-) .(Component side)

Verify that the actuator operates to the REC position.

Verify that the temperature actuator operates to the FRE position with reverse connecting.( REC(-) and FRE(+)) (Component side)

caution

Check for proper operation when BATT(12V) power is supplied and follow safety regulations.

Specification : Refer the specifications in Fig.1)

Fig.1)

Fig.1) Function of the actuator motor according to terminal connection type. (observe safety regulations)

Is measured value within specification?

	▶ Perform following procedures.
	▶ Substitute with a known-good Intake actuator and check for proper operation. If the problem is corrected, replace Intake actuator and then go to "Verification of Vehicle Repair" procedure.

■ Check Intake potentiometer(actuator)

Ignition "OFF"

Disconnect Intake potentiometer(actuator) and A/C control module main harness connector.

Ignition "ON", Engine "OFF".

10.

Measure voltage between Signal(F/B) terminal of Intake potentiometer(actuator) harness connector and chassis ground.(Component side)

Specification : Refer the specifications in fig.2)

Fig.2) Voltage value of Intake potentiometer(actuator) as a function of intake door position.

11.

Is measured value within specification?

	▶ Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Substitute with a known-good Intake potentiometer(actuator) and check for proper operation. If the problem is corrected, replace Intake potentiometer(actuator) and then go to "Verification of Vehicle Repair" procedure.
