CLIMATE CONTROL UNIT CONNECTOR B (26P)

A Short in the Sunlight

Sensor Circuit

1. Disconnect the sunlight sensor 2P connector.

Go to step 7.

Go to step 2.

2. Disconnect climate control unit connector B (20P).

3. Check for continuity between the No. 12 terminal of

climate control unit connector B (20P) and body
ground.

Repair short to body ground in the wire

between the climate control unit and the sunlight
sensor.

Go to step 4.

4. Reconnect the sunlight sensor 2P connector.

5. Reconnect climate control unit connector B (20P).

6. Test the sunlight sensor (see page 21-119).

Substitute a known-good climate control unit,

and recheck. If the symptom/indication goes away,
replace the original climate control unit.

Replace the sunlight sensor.

7. Disconnect climate control unit connector B (26P).

8. Check for continuity between the No. 19 terminal of

climate control unit connector B (26P) and body
ground.

Repair short to body ground in the wire

between the climate control unit and the sunlight
sensor.

Go to step 9.

9. Reconnect the sunlight sensor 2P connector.

10. Reconnect climate control unit connector B (26P).

11. Test the sunlight sensor (see page 21-119).

An Open in the Evaporator

Temperature Sensor Circuit

1. Disconnect the evaporator temperature sensor 2P

connector.

2. Measure the resistance between the No. 1 and

No. 2 terminals of the evaporator temperature
sensor.

• Without Navigation System: Go to step 3.
• With Navigation System: Go to step 6.

Replace the evaporator temperature

sensor.

3. Disconnect climate control unit connector B (20P).

4. Check for continuity between the No. 14 terminal of

climate control unit connector B (20P) and the No. 2
terminal of the evaporator temperature sensor 2P
connector.

Go to step 5.

Repair open in the wire between the climate

control unit and the evaporator temperature
sensor.

terminal of the evaporator temperature sensor 2P
connector.

Check for loose wires or poor connections at

climate control unit connector B (20P) and at the
evaporator 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 evaporator temperature
sensor.

6. Disconnect climate control unit connector B (26P).

7. Check for continuity between the No. 20 terminal of

climate control unit connector B (26P) and the No. 2
terminal of the evaporator temperature sensor 2P
connector.

Go to step 8.
