5. FAULT FINDING LOG
You will always be asked for this log:
–when requesting technical assistance from Techline,
–for approval requests when replacing parts for which approval is mandatory,
–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 INSTRUCTIONS
All work on components requires that the safety rules be obeyed to prevent damage or injury:
–Check the battery voltage to avoid incorrect operation of computer functions.
–Use the appropriate tools.
–Do not touch the discharge bulbs.
–Never work on the discharge bulb system while it is in operation: the voltage is 20,000 V or more. IMPORTANTIMPORTANT
All faults involving a complex system call for thorough diagnostics 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 item for communication
with the manufacturer.
IT IS THEREFORE OBLIGATORY TO FILL A FAULT FINDING LOG WHENEVER
THE TECHLINE OR THE WARRANTY RETURNS DEPARTMENT REQUESTS IT.

The xenon bulbs fitted to the system require a voltage of 20,000 V when switched on, then run on 85 V AC.
You must always disconnect the battery before doing any work on the headlights, bulbs, and high-voltage headlight
power transformer units.
To follow the method of removal-refitting of the constituent components of the system, see MR 370 (Scenic II)
or MR 361 (Espace IV) or MR 353 (Velsatis), Mechanical systems, 80C - Xenon Bulbs, Xenon bulb computer:
Removal – Refitting or MR 339 (Laguna II), Mechanical systems, 80 – Headlights, Xenon headlights.
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 calibrated using CF001computer calibration (see Configuration and programming) each
time a front or rear level sensor is replaced.
The following procedure should be applied before adjusting the headlight beam:
–check that there are no faults
–configure the vehicle type using command CF003 Vehicle type (see Configuration and programming)
–calibrate the computer using command CF001 (see Configuration and programming)
Next adjust the headlights manually, (see MR 370 (Scenic II) or MR 361 (Espace IV) or MR 353 (Velsatis),
Mechanical systems, 80C - Xenon bulbs, Xenon headlight: Adjustment or MR 339 (Laguna II), Mechanical
systems, 80 – Headlights, Xenon headlights).

AFTER REPAIRTurn on the dipped headlights and check that initialisation is performed.
If there is no initialisation, deal with the system faults.
Adjust the headlights manually after each computer calibration.
Carry out a road test followed by a check with the diagnostic tool.

C.O.: Dipped headlights signal line circuit open
1.DEF: Speed signal above maximum threshold
2.DEF: Speed signal in open or short circuit to + 12 V
3.DEF: Speed signal short circuit to earth detected while driving
4.DEF: Speed greater than 0 during initialisation
5.DEF: Computer not calibrated
6.DEF: Incorrect vehicle configuration

8.DEF: Actuator control line open circuit
9.DEF: Actuator control line short circuit to earth
10.DEF: Actuator control line short circuit at + 12 V
11.DEF: Battery voltage too low
NOTESThe fault is declared present after the dipped headlights are switched on, or during
a road test.
C.O
NOTESPriority when dealing with a number of faults.
Run a fault finding procedure on the UCH (see 87B, Passenger compartment connection unit) or UPC
(for Scénic) (see 87G, Engine compartment connection unit) to check the correct operation of the stalk.
Check the condition of the contacts and make sure that the xenon bulb computer is properly connected.
Check the continuity and absence of interference resistance in the following connection:
For Scénic II:
Black 6-track connector for the Protection and switching unit connector
track 5
For Vel Satis/Espace or Laguna II:
Black, 6-track connector of the UCH track 3B2Track 6 of the xenon
bulb computer.
If the fault is still present after these checks, replace the dipped headlights control stalk.

Left-hand headlight adjustment motor track 2Xenon bulb computer track 7
Check the condition of the connections as well as the xenon bulb computer and adjustment motor connections.
Repair if necessary.

NOTESOnly refer to this customer complaint after a complete check with the diagnostic tool.
Check the 1K (5A) fuse of the passenger compartment relay and fuse box.
Replace it if necessary.
Turn on dipped-beam headlights.
If the bulbs light but the system does not perform initialisation and no communication is possible, perform the
following checks:
Remove the timed power supply 40A relay A located in the passenger compartment fuse and relay box.
Check the condition of the connections and repair if necessary.
Measure the following resistance values:
–Power circuit: Resistance between tracks 85 and 86 of the relay.
If the resistance is not 65 ± 5 ΩΩ Ω Ω
, replace relay A.
–Control circuit: Resistance between tracks 30 and 87A of the relay.
If the resistance is not approximately 1 ΩΩ Ω Ω
, replace relay A.
Check the battery voltage and carry out the operations necessary to obtain a suitable voltage (9.5 V < battery
voltage <14.4 V).
Check for:
a + 12 V supply before ignition on track 16 of the diagnostic socket,
a + 12 V supply after ignition on track 1 of the diagnostic socket,
earth on tracks 4 and 5 of the diagnostic socket.
Repair if necessary.
If the fault is still present, contact the Techline.
