Programming and Relearning

System start-up procedure
When the ignition is switched on the Rear seat entertainment module (RSE) performs a basic internal system check and starts the start-up procedure with the screens. The following occurs:
1. The ignition is switched on.
2. The illuminated DVD player buttons come on. If a TV receiver is installed, the receiver's status LED comes on.
3. The Rear seat entertainment module (RSE) feeds the connections #E1 (left-hand screen) and #E13 (right-hand screen) with voltage.
4. The Rear seat entertainment module (RSE) sends a wake-up signal of approximately 11.5 V to connection #E2 for the left-hand screen.
5. The left-hand screen then returns an OK signal to the Rear seat entertainment module (RSE) via the internal CAN network.

Note! If the screen does not respond on the CAN network, the Rear seat entertainment module (RSE) makes a further two attempts according to the pattern below (*). If the screen does not respond the Rear seat entertainment module (RSE) continues as set out in section 8 below.

6. The Rear seat entertainment module (RSE) returns a message to the left-hand screen on the CAN network which assigns the screen number 1. This is necessary for the video and audio to be addressed to the right screen and so that commands from the remote control can be executed on the right screen.
7. Communication for the left-hand screen is now OK.
8. The Rear seat entertainment module (RSE) sends a wake-up signal of approximately 11.5 V to connection #E14 for the right-hand screen.
9. The right-hand screen then returns an OK signal to the Rear seat entertainment module (RSE) via the internal CAN network.

Note! If the screen does not respond on the CAN network, the Rear seat entertainment module (RSE) makes a further two attempts according to the pattern below (*). If the screen does not respond the Rear seat entertainment module (RSE) continues as set out in section 12 below.

10. The Rear seat entertainment module (RSE) returns a message to the right-hand screen on the CAN network which assigns the screen number 2.
11. Communication for the right-hand screen is now OK.
12. The Rear seat entertainment module (RSE) checks whether the result of the wake-up attempt according to section 7 and 11 is OK. It then performs a communication check with the DVD player.
- If the wake-up attempt and communication check are OK, the control module continues as set out in section 14.
- If both the wake-up attempt/communication check fail, the control module continues as set out in section 13.
1. The illuminated DVD player buttons are on for approximately 60 seconds.
2. The illuminated DVD player buttons, except the POWER button, go out. If the TV receiver is installed the receiver's status LED goes out.
3. The start-up procedure is implemented and the system switches to standby.
4. The system can now be started using the POWER button on the DVD player or the remote control.
(*) Wake-up signal (signal pattern with a fault)
High signal (approx. 11.5 V) is sent for approx 1 second (first attempt).
If there is no response a low signal is sent (approx. 0 V) for approximately 3 seconds.
High signal (approx. 11.5 V) is sent for approx 1 second (second attempt).
If there is no response a low signal is sent (approx. 0 V) for approximately 3 seconds.
High signal is sent (approx. 11.5 V) and remains continuously high (third and last attempt).
Start-up times
Start-up without faults detected takes approximately 10 seconds.
Start-up with communication fault on one screen takes approximately 85 seconds.
Start-up with communication fault on both screens takes approximately 95 seconds.
The times above should only be seen as a guide and are not exact times.
