6. Disconnect climate control unit connector B (26P).
7. Check for continuity between the No. 18 terminal of
climate control unit connector B (26P) and the No. 1
terminal of the outside air temperature sensor 2P
connector.
Go to step 8.
Repair open in the wire between the climate
control unit and the outside air temperature
sensor.
8. Check for continuity between the No. 1 terminal of
climate control unit connector B (26P) and the No. 2
terminal of the outside air temperature sensor 2P
connector.
Check for loose wires or poor connections at
climate control unit connector B (26P) 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.
