9. Check for continuity between the climate control
unit 32P connector terminal No. 19 and the outside
air temperature sensor 2P connector terminal No. 2.
Check for loose wires or poor connections at
the climate control unit 32P 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.
Repair open in the wire between the climate
control unit and the outside air temperature
sensor.
1. Clear the DTC with the HDS.
2. Turn the ignition switch to LOCK (0), and then turn
to ON (II).
3. Do the self-diagnostic with the HDS (see page
21-10) or climate control unit (see page 21-11).
4. Check for DTCs.
Go to step 5.
Intermittent failure.
5. Turn the ignition switch to LOCK (0).
6. Remove the outside air temperature sensor
(see page 21-68), and test it (see page 21-68).
Go to step 7.
Replace the outside air temperature sensor.
7. Disconnect the climate control unit 32P connector.

4. Check for DTCs.
Go to step 5.
Intermittent failure, check for loose wires or
poor connections on the sunlight sensor circuit.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the sunlight sensor 2P connector.
7. Disconnect the climate control unit 32P connector.
8. Check for continuity between the climate control
unit 32P connector terminal No. 24 and the sunlight
sensor 2P connector terminal No. 2.
Go to step 9.
