3. RECAP
Procedure:
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition
feed).
Proceed as follows:
– vehicle card in card reader (scenario 1: keyless vehicle, entry level model, no hands-free; and scenario 2: top
of the range, hands-free),
–Press and hold Start button (longer than 5 seconds) with start-up conditions not fulfilled,
– connect the diagnostic tool and perform the desired operations.
To cut off + after ignition, proceed as follows:
–disconnect the diagnostic tool,
–Press the Start button twice briefly (less then 3 seconds),
– Check that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.
Faults
Faults are classed as either present or stored (having appeared in a certain situation and then disappeared, or being
still present but not diagnosed in the current situation).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used after the
+ after ignition feed is switched on (without acting on the system components).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the Instructions section.
If the fault is confirmed when the Notes are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
– The electric lines on which there is a fault;
– The connectors on those lines (corrosion, bent pins, etc.);
– The resistance of the faulty component;
– The condition of the wires (insulation melted or cut, chafing, etc.).
Conformity check
The aim of the conformity check is to check statuses and parameters that do not produce a fault display on the
diagnostic tool when they are inconsistent. Therefore, this phase is used:
–to perform fault finding on faults that do not have a fault display, and which may correspond to a customer complaint.
–to check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section features the fault finding procedures for statuses and parameters, and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the diagnostic tool check is correct, but the customer complaint persists, it should be dealt with according to the
customer complaint.
A summary of the overall procedure to follow is provided on the following page in the form
of a flow chart.

5. FAULT FINDING LOG
You will always be asked for this report:
– when requesting technical assistance from the Techline,
–for approval requests when replacing parts for which approval is obligatory,
–to be enclosed when returning monitored parts on request. The log is needed for warranty compensation, and
enables better analysis of the parts removed.
6. SAFETY ADVICE
All work on components requires that the safety rules be obeyed to prevent damage or injury:
– Make sure the battery is properly charged to avoid damaging the computers with a low load.
– Use the appropriate tools.
– Do not touch the xenon bulbs.
– Never work on the xenon light system while it is on: the voltage is 20,000 V or more.
WARNING!
IMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential item for communication with the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME
FAULT FINDING IS
CARRIED OUT.

Program no.: V010
VDIAG No.: 05
Fault finding - System operation
1- XENON LIGHT SYSTEM COMPONENTS
The system consists of the following components:
–Front vehicle level sensor (the xenon light computer is built into this sensor).
– Rear vehicle level sensor.
–Right and left-hand headlight adjustment motor.
– Bulb high-voltage power unit (ballast).
– Xenon lights.
The K line can be used for fault finding; the system is not multiplexed.
2- SYSTEM OPERATION
When the control lever is in position (dipped headlights), it sends a signal to the UCH. The UCH processes the signal
and, through the CAN network, asks the Protection and Switching Unit to turn on the xenon lights.
When the bulbs come on, the adjustment motor moves through three positions: low, high, initial.
This is its intialisation.
If the vehicle is travelling faster than 6 mph (10 km/h) when the bulbs come on, there is no intialisation.
The computer manages various signals to adjust the amount of light:
– Vehicle speed: signal from the ABS computer. Above 18 mph (30 km/h), the adjustment motors raise the
bulbs to provide optimum lighting for the driver.
– Vehicle front and rear height: signals from the front and rear height sensors. These sensors track the
angular motion of the car's body (deceleration, acceleration, vehicle loaded). The computer then controls
the motors to adjust the beam and provide optimum lighting.
– System initialisation:
When the vehicle is unlocked, even if the dipped headlights are off, the system moves the adjustment motors to the
low position and then the initial position.
This initialises the system.

3- SYSTEM CONFIGURATION/CALIBRATION
To calibrate and configure a new computer on a vehicle, follow the configuration procedures in the following order.
a - Vehicle type (CF003)
This configuration activates the adjustment strategies designed for the body type.
The new strategies only take effect after the ignition is switched off and the doors are locked.
Perform configuration as follows:
– Enter the xenon lights fault finding mode.
– Make sure that the initial vehicle position indicated by the front and rear sensors is within the allowed range.
– Run configuration CF003 according to the vehicle type:
– J84 (MPV 5 seats)
– R84 (MPV 7 seats LWB)
– SUV84 (MPV 4x4)
– Exit fault finding mode.
– Switch off the ignition.
– Lock the doors with the card.
– The vehicle type has been programmed.
–After unlocking the doors, turn the ignition back on.
– See that the vehicle type has been properly identified by reading configuration LC001, Vehicle type.
b - Computer calibration CF001
This calibration must be performed when a system component is replaced (e.g. sensor, headlight etc.).
It enables the computer to store the vehicle's reference level.
To ensure proper configuration and calibration, follow this procedure:
– Check tyre pressure and adjust if faulty.
– Park the vehicle on a level surface under normal driving conditions (luggage compartment empty).
– Vehicle stopped, no variation in attitude (no door rattling).
–Driver aboard.
– Fuel tank full.
Once computer calibration has been performed, check conformity of the light beam.
If it is incorrect, adjust the headlights manually.
4- DEFECT MODE
If a system component is defective, no indicator lights up on the instrument panel.
The system then switches to defect mode.
If the computer detects a system fault, it sets the adjustment motors to the low or initial position.
If the computer detects a fault, there is no longer any intialisation when the lights are turned on.

Fault finding - Component replacement
The system's xenon lights require a voltage of 20,000 V when switched on, then run on 85 V AC.
The battery must without fail be disconnected before any work on the headlights, bulbs, and high-voltage headlight
power transformer units.
Refer to MR 370, 80C - Xenon lights, Xenon light computer: Removal - Refitting for the Removal - Refitting
procedure for the components of the system.
It is forbidden to supply a bulb if it is not installed in the headlight (danger that you might damage your eyes).
The computer must be programmed using command CF001 each time the front or rear level sensor is replaced (see
Configuration and programming).
The following procedure should be applied before adjusting the beam height:
– check that there are no faults
– configure the vehicle type using command CF003 (see Configuration and programming)
–program the computer using command CF001 (see Configuration and programming)
Then manually adjust the headlight beam, see MR 370, 80C - Xenon lights, Xenon headlights: Adjustment.
