(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）-C031（1）
C021（A8）-C031（2）
C021（A4）-C031（3）
＜2Ω
C021（12）-C031（5）
C021（B12）-C031

Check whether the result is normal?
Yes> go to step 3
No > Maintenance or replace harness.
3 . Check temperature regulation servo motor
(a) Ignition switch: "OFF".
(b) Disconnect the connector C031 of temperature regulation servo motor.
(a) Check the connector C031 function of the
temperature regulation servo motor.
