Trouble Eliminating of Entertainment System
(1)The main frame can’t be started.
The main frame can’t work normally or the key light can’t illuminate and so on,as shown in Fig.3.44
Elimination Methods:
Check whether the fuse of on-board sound system is burned or not.(The fuse of main frame is 10A,and the fuse of screen is 5A),as shown in Fig.3.45.

(2)Mobile phone interconnection can’t be connected
①Check the system version information of mobile phone to see whether it is on the list of compatibility.
②Check whether the connection wire is the original data wire(The data wire has more than one function of electrifying).
③Make sure that the developer mode and USB debugging of mobile phone have been opened.(https://www.daowen.com)
④Make sure that it matches with Car Mode,and is accessible,because some“Phone Manager”will restrict partial access permission.
⑤When inserting the phone,choose“Check the Photos”or“File Management”(different phones have different option instructions)instead of“Only Being Electrified”.
⑥Car Mode must be installed on the mobile phone and when the installation requirement pops out on the phone,you must click“Agree to Install”.
⑦If Car Mode on the phone is the old version of other vehicles,you need to delete it and reboot and reinstall the software.
(3)Dialog box“Error”pops out when main frame is started and touch screen fails
When the main frame is electrified,the“Error”dialog box pops out on the main interface or the touch screen fails,as shown in Fig.3.46.You can solve it by updating the software by referring to Part 3 in the teaching material.If not,use another main frame to test.

(4)Occasional splash screen and occasional unsteady performance.
Disassemble the main frame and see whether there are additional electronic products such as navigation module or E-dog.If yes,there is bound to be certain disturbance.So disconnect them,and try again.If no,use the replacement method to eliminate possibilities(See whether the phenomenon still exists after using another screen or main frame),as shown in Fig.3.47.For example,increase navigation module by increasing LVDS wire harness.
