Faults: Faults are declared as either present or stored (depending on whether they appeared in a certain context and have disappeared since, or whether they remain present but have not been diagnosed within the current context). The present or stored status of faults should be taken into consideration when the diagnostic tool is used following the + after ignition supply being 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 notes 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 electrical lines which correspond to the fault, the connectors on these lines (corrosion, bent pins, etc.), the resistance of the component detected as faulty, the condition of the wires (melted or split insulation, wear). 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 because they are inconsistent. Therefore, this phase is used to: run fault finding on faults which are not displayed but which may correspond to a customer complaint, check that the system is operating correctly and that there is no risk of a fault recurring after repair. This section provides the fault finding procedures for statuses and parameters and the conditions for testing 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 check using the diagnostic tool is all clear, but the customer complaint is still present, the fault should be dealt as a Customer complaint. A summary of the overall procedure to follow is provided on the following page in the form of a flow chart

4. FAULT FINDING PROCEDURE (continued) 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 their crimping (no crimping on the insulating section). Make sure that the clips and tabs are properly locked in the sockets. Make sure 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 + 12 V or to another wire. If a fault is detected, repair or replace the wiring harness.

5. FAULT FINDING LOG NOTE Any fault on a complex system requires thorough fault finding with the appropriate tools. The FAULT FINDING LOG, which should be completed during the fault finding procedure, ensures a record is kept of the procedure carried out. It is an essential document when consulting the manufacturer.

IMPORTANT!

IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDING IS CARRIED OUT. You will always be asked for this log: when requesting technical assistance from the Techline. for approval requests when replacing parts for which approval is obligatory. to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty reimbursement, and enables better analysis of the parts removed.

6. SAFETY GUIDELINES All work on components requires the observation of safety rules to prevent damage or injury: Check that the battery is properly charged to avoid damaging the computers in the event of a low load. Do not smoke. Use the appropriate tools. Do not touch the xenon bulbs, and do not work on the xenon bulb system when it is in operation, as the voltage can be more than 20,000 V.

HEADLIGHTS Fault finding - System operation

80B

1. System description: The system on which a fault finding is being performed is fitted with xenon bulbs. This system allows: dynamic adjustment of headlights (xenon bulb function).

2. System layout: Xenon bulb function: The system comprises: a computer to manage information and control the actuators a front height sensor mounted on the front axle to measure vehicle body height variations a rear height sensor mounted on the rear axle to measure vehicle body height variations 2 adjustment motors mounted inside the headlights 2 voltage transformers (ballast) which cannot be diagnosed 2 xenon bulbs located inside the headlights which cannot be diagnosed.

3. Operation programming Xenon bulb function: The user requests that the dipped headlights are switched on by pressing on the control stalk. The driver request is received by the UCH which sends it to the computer via the vehicle multiplex network. The xenon bulb computer operates the headlight adjustment motors. Initialisation: When the xenon bulbs come on, the headlights run through initialisation. This function consists of operating the actuators to three different beam heights. The driver is notified that the system is operating correctly. If the computer is faulty, the initialisation is not performed when the bulbs are switched on. Initialisation is performed if the following conditions are fulfilled: stalk in dipped headlights position system initialised vehicle stationary or speed < 6 mph (10 km/h).

Dynamic adjustment: This function allows adjustment of the xenon bulb beam height as a function of variations in vehicle body height and vehicle speed. This information is provided by: the front and rear body sensors the ABS computer (speed signal via the multiplex network) the longitudinal acceleration sensor The xenon bulb computer operates the adjustment motors according to the information received, thereby obtaining optimal beam characteristics under all driving conditions. Raise/lower according to speed: This function allows operation of the adjustment motors to elevate the beam at a speed of more than 18 mph (30 km/h), to optimise driving comfort. The beam is adjusted as a function of the vehicle speed. If the vehicle speed is < 18 mph (30 km/h), the adjustment motors lower the beam.
