1.

Ignition "OFF"

2.

Disconnect ambient sensor and Connect A/C control Module main harness connector.

3.

Measure resistance between Signal(+) terminal of ambient sensor harness connector and Sensor ground harness connector. (Component side)

Specification : Refer the specifications in Fig.1)

Fig.1)

Fig.1) ※ Specifications : Resistance value of ambient sensor as a function of temperature .

※ The actual value may differ from it according to various engine condition.

4.

Is "resistance" display near the specified value?

	▶ Go to "Check A/C control Module" procedure.
	▶ Substitute with a known-good ambient sensor and check for proper operation. If the problem is corrected, replace ambient sensor and then go to "Verification of Vehicle Repair" procedure.

5.

Ignition "OFF"

6.

Disconnect Ambient Temp. sensor (+) and Connect A/C control Module main harness connector.

7.

Ignition "ON"(ENGINE "OFF").

8.

Measure voltage between Signal(+) terminal of Ambient Temp. sensor (+) harness connector and chassis ground. (Component side)

Specification : approx. 5V

9.

Is "voltage" display near the specified value?

	▶ 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 A/C control Module and check for proper operation. If the problem is corrected, replace A/C control Module and then go to "Verification of Vehicle Repair" procedure.
