Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to the + 12 V feed or with another wire.
If a fault is detected, repair or replace the wiring harness.

INSTRUMENT PANEL
Fault finding - Function
The instrument panel provides the following functions:
–Illumination of the direction indicator light:
The dual direction indicator light comes on if the driver has manipulated the indicator switch to inform of a change in
direction.
–Illumination of the light indicator lights:
–The side light indicator light comes on when the side lights are switched on.
–The dipped headlights indicator light comes on when the dipped headlights are switched on.
–The main beam headlights indicator light comes on when the main beam headlights are switched on.
–The front fog light indicator light comes on when the front fog lights are switched on.
–The rear fog light indicator light comes on when the rear fog lights are switched on.
–Side lights reminder buzzer:
–The “side lights reminder” buzzer sounds when the driver's or passenger's door is opened, with the APC off and
the side lights on, to warn the driver that the lights are still on.
–Operation of the “automatic headlighting activation - deactivation or automatic locking when driving”
buzzer:
–The “connection” warning sound is emitted by the instrument panel buzzer when the “automatic headlighting” or
“automatic locking when driving” functions are activated.
–The “disconnection” warning sound is emitted by the instrument panel buzzer when the “automatic headlighting” or
“automatic locking when driving” functions are deactivated.
–“Overspeed function - Arabia” buzzer operation:
Warns the driver that the speed threshold has been exceeded, depending on the country and the equipment.

– Fuel level gauge:
The fuel level gauge informs the driver of the fuel level remaining in the tank using a bargraph. It also indicates a low
fuel level using a “fuel level low” warning consisting of a flashing red square.
–Speed display:
The speed display informs the driver of the current vehicle speed in km/h or miles/h depending on the
“distance units” configuration.
If the “Service” warning light and " - - " light up in place of the vehicle speed, refer to the “Service warning light
illumination” insert.
–Multifunction display:
The multifunction display centralises the following information:
–Mileometer,
–Trip mileage.
–Distance/time before service
–Cruise control/Speed limiter (depending on configuration)
–Clock (entry level version)
–Exterior temperature (depending on configuration)
It is possible to shift from one piece of information to another in the order above, simply by pressing the
“Trip computer” button located on the end of the windscreen washer control.
–Mileometer and trip mileage:
Respectively indicates the total distance travelled by the vehicle since it was manufactured and the distance
travelled since the trip mileage was last reset.
The distance travelled is displayed in “km” or “miles” depending on the configuration.
–Distance/time before service:
Shown on the multifunction display, indicates the distance to be travelled before the next service.
If the “Service” warning light and “Distance/time before service” warning light come on simultaneously, refer to the
“Service warning light illumination” insert.

–Fixed illumination + 5 seconds buzzer: Parking brake engaged when driving.
–Flashing: Calibration of the electronic braking distribution.
If the “Stop” warning light and “Brake” warning light come on simultaneously, refer to the “Stop warning light
illumination” insert.
–Illumination of the “seat belt reminder” warning light:
Illumination of the “seat belt reminder” warning light indicates the following statuses to the driver:
–Fixed illumination: Seat belt reminder.
–Flashing + “Moderate seat belt reminder buzzer” signal:
Seat belt reminder + 12 mph (20 km/h).
–Flashing + “Loud seat belt reminder buzzer” signal + Radio cut off:
Seat belt reminder following the seat belt reminder warning + 12 mph (20 km/h).
