1. Remove the in-car temperature sensor (see page
21-117).
2. Measure the resistance between the No. 1 and
No. 2 terminals of the in-car temperature sensor.
Check for a change in resistance by heating or
cooling the sensor with a hair drier.
• Without Navigation System: Go to step 3.
• With Navigation System: Go to step 6.
Replace the in-car temperature sensor.
3. Disconnect climate control unit connector B (20P).
4. Check for continuity between the No. 16 terminal of
climate control unit connector B (20P) and the No.
2 terminal of the in-car temperature sensor 2P
connector.
Go to step 5.
Repair open in the wire between the climate
control unit and the in-car temperature sensor.
5. Check for continuity between the No. 11 terminal of
climate control unit connector B (20P) and the No. 1
terminal of the in-car temperature sensor 2P
connector.
Check for loose wires or poor connections at
climate control unit connector B (20P) and at the in-
car 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 in-car temperature sensor.
