DIAGNOSTICS - AIR CONDITIONING SYSTEM 04-317

(d) Measure the electrical resistance based on
the value in the following form.
Standard electrical resistance (check
whether there existent an open circuit)

Multimeter connection Standard value
04
C021（B4）-C014（1）

C021（A7）-C014（2）
C021（A4）-C014（3）
＜2Ω
C021（A13）-C014
（5）

C021（B13）-C014
（6）

Check whether the result is normal?

Yes> go to step 3
No > Maintenance or replace harness.

3 . Check the mode air door servo motor

(a) Ignition switch: "OFF".
(b) Disconnect the connector C014 of the mode air door servo motor.

(c) Check the function of mode air door servo
motor C014.

voltage
between pins 5 battery (-)-6 servo motor
and 6 operation

Check whether the result is normal?

Yes > Replace the air conditioner controller.
No > Replace the mode air door servo motor, and verify again whether the failure
exists.
