DIAGNOSIS-AUDIO SYSTEM 62-265

(d). Measure the resistance between the No.7
and No.8 pin of connector C67 on the
sound unit and the No.1 and No.2 pin of
connector I03 on the rear door loudspeaker
LH with the multimeter.
Standard resistance: (check whether there 62
is an open circuit)

Connect the pin by Standard value
multimeter
C67(7) - I03(1) ≤2Ω

C67(8) - I03(2) ≤2Ω

(e). Measure the resistance between the No.1
and No.2 pin of connector C67 on the
sound unit and the No.1 and No.2 pins
of connector H03 on the rear door
loudspeaker RH with the multimeter.
Standard resistance: (check whether there
is an open circuit)

Connect the pin by Standard value
multimeter
C67(1) - H03(1) ≤2Ω

C67(2) - H03(2) ≤2Ω
Is the result normal?
Yes>To step4.
No >Repair the harness of the open circuit between connector C67 of the sound unit and
the loudspeaker.

4. Comparing with the similar models

(a). Set the sound units "FAD" and "BAL" to the same level.
(b). Comparing with the similar models.

Check whether the loudspeaker volume is identical?
Yes>Inspection end.
No >Replace the CD/DVD sound unit.
