1. Clear the DTC with the HDS.

2. Operate the climate control system in several

modes.

3. Check for DTCs using the HDS or self-diagnostic.

Go to step 4.

Intermittent failure, check for loose wires or

poor connections on the outside air temperature
sensor circuit.

4. Turn the ignition switch OFF.

5. Remove the outside air temperature sensor

(see page 21-52) and test it (see page 21-52).

Go to step 6.

Replace the outside air temperature sensor.

6. Disconnect the climate control unit 30P connector.

7. Check for continuity between the climate control

unit 30P connector No. 9 terminal and the outside
air temperature sensor 2P connector No. 2 terminal.

Go to step 8.

Repair open in the wire between the climate

control unit and the outside air temperature
sensor.

the climate control unit 30P connector and at the
outside air temperature sensor 2P connector. If the
connections are good, substitute a known-good
climate control unit, and recheck. If the symptom/
indication goes away, replace the original climate
control unit.
