A. Initial Inspection and Test.

1. Read the dealer fault report.

2. Examine the module. Note any bent or missing connector pins or other obvious damage.

3. Plug the module into the test kit and test as follows. Note any faults found.

Step Procedure Check that . . Verification

1 Connect the control module to the test

kit. Plug the output from the DVD into

CN1 (see figure 1) on the control

module. Connect a 12.5 V DC supply to

the permanent and ignition inputs of the

test kit.

The DVD switches on.

Module power

3 Press 'MENU' on the remote. Navigate

to 'MEDIA SELECT' then press 'ENTER'.

Select DVD and press ENTER again.

The menu appears on TFT A. Menu chip.

4 Aim the remote at TFT screen B and

select DVD as per step 2 above. The menu appears on TFT B Control power to

6 Aim the controller at TFT A, press Stop,

wait and then press PLAY.

7 Aim the controller at TFT B and press

Menu. Press Stop and then PLAY as

above.

The DVD pauses then continues to

play each time. IR coms

10 Plug the DVD output into CN2. Use the

remote to select AUX 1 on both screens.

11 Plug the DVD output into CN3. Use the

remote to select AUX 2 on both screens.

The picture from the DVD appears

on TFT A and TFT B as each

selection is made and there is sound

on both channels.

C. Diagnosis and Repair.

1. Connect the open control module to the test kit.

2. Connect the 12.5 V power supplies to the test kit.

3. Compare the symptoms observed under A. Initial Inspection and Test with the symptoms

listed below to locate the components likely to be faulty and effect the necessary repairs.

Service Manual – Renault System

D. Reference

General Description:

General Description:General Description:

General Description:

The control module is central to the Entertainment system. It interprets and implements

commands entered by the user using the system's infrared remote control. These

commands are relayed to the control module via the system's infrared sensors mounted in

the screen modules. It also distributes power to the system and detects the vehicle's

ignition state via a sense wire running from CN1 to the vehicle's ignition switch. This

enables it to limit battery drain whilst the vehicle is not in use.

The control module receives audio and video inputs from the DVD Player via connector

CN1 and from the vehicle's TV tuner (if fitted) via connector CN2. It is also able to receive

a further audio/video input and supply a low-level two-channel audio output via CN3.

Technical Description:

Technical Description:Technical Description:

Technical Description:

A micro-controller in the Control Module supplies and controls the power to the system via

an I2C bus. On receipt of a

power-on

command from the Infrared Controller it performs a

simple system check and then sends commands to other parts of the system to bring them

on line.

When a screen has been selected using the infrared remote control the Control Module

identifies the selected screen and displays on it a menu providing the user with access to

the functions detailed below:

• Independent switching of three Audio-Visual inputs (DVD, TV and AUX)

• Video manipulation (Colour, brightness, contrast and aspect ratio of the display.)

• Audio processor (Bass, Treble and Volume)

• On-Screen instructions language selection

• Switch on/off individual screen displays

The Control Module also determines which media source has been routed to the selected

screen and relays commands in the appropriate protocol.

For example if, while Screen A is displaying the DVD transmission, an infrared play

command is detected at screen A, it would be captured, stored and relayed to the DVD in

the DVD's Infrared protocol. If screen B is displaying a TV transmission the play command

would be transmitted in the vehicle's TV tuner infrared protocol.

A non-volatile memory stores the display instruction language in use and the current Audio

and Video settings for each output channel. These settings are reloaded on power-up with

the exception of the audio volume level, which defaults to a low state.

Support equipment that has been powered off is detected by the lack of video sync pulse.

This can be caused by auto shutdown after extended pause mode. When this happens the

module responds by transmitting a power-on command to the support equipment until it is

ready to accept it and power up. The supply of the video sync pulse then resumes and the

module stops transmitting the power-on command.
