HELP IN DIAGNOSIS : TELEMATICS RT4 (SUMMARY)

RT4 AUDIO/TELEPHONE SYSTEM

1. Concerns All vehicles equipped with a telematic unit RT4.

2. Presentation : Document This document is an addition to the check procedures of the diagnostic tools. 2.1. Instructions General procedure for using the diagnostic assistance document and the diagnostic tool. 2.2. Generality Reminder : Telematics RT4. 2.3. Recommendations/precautions

URGENT : Risk of the multifunction display and telematic unit being rendered useless : Do not disconnect the connection cable between the telematic unit and the multifunction display when the telematic unit 40-way connector is connected.

Before any operations : Check : The battery voltage The fuses The correct position of the shunt located on the built-in systems interface (the shunt must be in position

"customer") The built-in systems interface must not be in "ECO mode" The telematics unit must be powered and connected to the network

CAUTION : Special precautions must be taken when connecting and disconnecting the telematic unit and multifunction display harnesses, to avoid permanent damage to the multifunction display / Data communication ECU .

Dismantling : multifunction screen / Data communication ECU : 1 - Switch off the ignition ; Switch off all power consuming equipment to allow the networks to switch to

standby 2 - Get out of the vehicle ; Check that all the openings are closed correctly (Do not lock the doors) 3 - Wait 3 minutes 4 - Disconnect the battery 5 - Disconnect the telematic unit 40-way connector 6 - Unplug : The multifunction display 7 - Disconnect the telematic unit aerials 8 - Connect the battery

assembly : multifunction screen / Data communication ECU : 1 - Switch off the ignition ; Switch off all power consuming equipment to allow the networks to switch to

standby
