(3) Check speaker
Disconnect speaker connector, test the resistance between speaker terminals, the resistance shall
be 2~9Ω. If it is normal, proceed to the next step; if not, replace speaker.
(4) Check connector between audio system and speaker
If it is normal, proceed to the next step; if not, repair or replace wiring and connector.
(5) Check CD player assembly
① Test the voltage between audio system assembly connector terminal A7 and vehicle body, the
voltage shall be 10~14V.
② Test the voltage between audio system assembly connector terminal A8 and vehicle body, the
voltage shall be less than 1Ω.
③ Turn ignition switch to ACC, test the voltage between audio system assembly connector
terminal A4 and vehicle body, the voltage shall be 10~14V.
If all above is normal, check and replace CD player assembly; if not, repair or replace wiring and
connector.

4. Can not put in CD or CD comes out immediately after putting in, can not play CD disk

(6) Check CD player assembly
① Test the voltage between audio system assembly connector terminal A7 and vehicle body, the
voltage shall be 10~14V.
② Test the resistance between audio system assembly connector A8 and vehicle body, the
resistance shall be less than 1Ω.
③ Turn ignition switch to ACC, test the voltage between audio system assembly connector
terminal A4 and vehicle body, the voltage shall be 10~14V.
