Repair procedures

Removal

[4DR]

1.	Disconnect the negative (-) battery terminal.

2.	Remove the luggage side trim [RH]. (Refer to Body - "Luggage Side Trim")

Loosen the nuts (A) from amplifier.

Tightening torque :

3.9 - 5.8 N·m (0.4 - 0.6 kgf·m, 2.8 - 4.3 lb·ft, 34.7 - 52.0 lb·in)

4.	Remove amplifier (B) after disconnect the connector (A).

[5DR]

1.	Remove the subwoofer. (Refer to AVN System - "Speaker")

Loosen the nuts (A) from amplifier.

Tightening torque :

3.9 - 5.8 N·m (0.4 - 0.6 kgf·m, 2.8 - 4.3 lb·ft, 34.7 - 52.0 lb·in)

3.	Remove amplifier (B) after disconnect the connector (A).

Installation

1.	Install in the reverse order of removal.

Inspection

•	Warning and guide sounds regarding engine start and driving are generated by the external amplifier. Please refer to the following: (Instrument Cluster and Gauge - Refer to "Instrument Cluster")

•	When the external amplifier or speakers are replaced with other products, a failure may occur in the amplifier and warning and guide sounds (excluding the ETCS guide sound) may not be generated.

•	Virtual engine sound inside the vehicle (occurs in Sport mode) is generated by the external amplifier. Therefore, if the external amplifier or speakers are replaced with other products, a failure may occur in the amplifier and virtual engine sound may not be generated properly.

In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (KDS).

(1)	Self diagnosis : Checking failure and code number (DCT).

(2)	Current data : Checking the system input/output data state.

(3)	Actuation test : Checking the system operation condition.

(4)	Additional function : Controlling other features including system option setting and zero point adjustment

2.	Select the 'Car model' and the system to be checked in order to check the vehicle with the tester.

3.	Select the 'Amplifier' to check the AVN.

4.	Select the 'Current data" menu to search the current state of the input/output data. The input/output data for the sensors corresponding to the Amplifier can be checked.
