DIAGNOSTICS - AIR CONDITIONING SYSTEM 04-313

(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
A001（3）-A024（11）
＜2Ω
A001（2）-A024（29）

Check whether the result is normal?
Yes> go to step 8
No > Maintenance or replace harness.

8 . Check the harness and connectors (air conditioner controller - engine control
unit)
(a) Disconnect battery negative cable.
(b) Disconnect the connector C021 of air-condition controller.
(c) Unplug the engine electronic control unit A024.

(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

C021（B3）-A024 ＜2Ω
（20）

Check whether the result is normal?

Yes > Go to step 9.
No > Maintenance or replace harness.

9 . Check the harness and connectors (relay of air conditioner compressor -
magnetic clutch)
(a) Unplug the relay R14 of air conditioner compressor
(b) Unplug the connector E021 of magnetic clutch.
