Fault finding - Role of components
Role of main components
–Display: displays various multimedia system data such as the station selected, time, CD listing and satellite
guidance information.
–Steering column control: allows the various system functions to be used via the steering wheel control.
–Speakers and tweeters: relay the sound from the multimedia system into the vehicle.
–CD changer: enables compact discs to be loaded and music to be relayed to the receiver.
–AM/FM aerial: receives radio signals from various transmitters.
–GPS aerial: receives various data transmitted by satellites.
–Radio/navigation computer: manages the various multimedia system functions according to user requests and
transmits audio data to the vehicle via the speakers.
–Cartographic map DVD: loads maps into the navigation computer.
–AM/FM aerial amplifier: improves the reception of AM/FM signals.
–Multimedia network interface unit: enables information to be exchanged between the “vehicle” and “multimedia”
multiplex networks. This computer is involved in activating the multimedia system.

WHEEL ACTION
NOTESThere must be no present or stored faults.
Engine stopped, ignition on.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2,
Trafic II ph2 or Kangoo 2.
Check the condition and connection of the connector of component 325 (Scénic II ph2 and Kangoo 2: 1519)
and of the black 24-track connector of component 1714.
If the connectors are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
Scénic II ph2 and Kangoo 2:
–connection code 34AT,
–connection code 34AR,
–connection code 34AS,
–connection code 34AQ,
–connection code 34AU,
–connection code 34AP,
between components 1714 and 1519.
Trafic II ph2 and Espace IV ph2:
–connection code 34AT,
–connection code 34AR,
–connection code 34AS,
–connection code 34AQ,
–connection code 34AU,
–connection code 34AP,
between components 1714 and 325.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that the wheel is operating correctly by checking the continuity between the following connections:
–34AR and 34AT
–34AR and 34AU
–34AR and 34AS
on component 325 or 1519.
If there is no continuity, replace component 325 or 1519.
–Espace IV ph2 (see MR 405 Mechanical systems, 83C, On-board telematics system).
–Scénic II ph2 (see MR 370 Mechanical systems, 84A Control - signals, Steering wheel controls: Removal
- Refitting).
–Trafic II ph2 (see MR 408 Mechanical systems, 86A Radio, Radio control satellite: Removal - Refitting).
If the fault is still present, contact Techline.
AFTER REPAIRRepeat the conformity check from the start.
