(b) Use a multimeter to measure the resistance
between pin 4 of connector C044 of acoustics
unit and the ground.
Standard resistance (check whether there
is short circuit)
04 Multimeter connection Standard value
C044(4) - ground ＞1MΩ
Check whether the result is normal?
Yes > Go to step 3.
No > Replace fuse: F22 (7.5A), and repair the to-earth short-circuit of circuit from fuse
F22 (7.5A) to pin 7 of connector C044 of acoustics unit.
3 . Check the acoustics unit module
(a) Disconnect the battery negative cable,
disconnect the connector C044 of the
acoustics unit.
CAUTION
Be careful not to drop the acoustics unit.
