3. REMINDERS
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after
ignition feed).
Proceed as follows:
with the vehicle card in the RENAULT card reader,
press and hold the Start button (for more than 5 seconds) with start-up conditions not fulfilled,
connect the diagnostic tool and perform the required operations.
Note:
The left-hand and right-hand xenon bulb computers are powered when the dipped headlights are lit. Therefore
fault finding can only be carried out on them after the ignition has been switched on in fault finding mode (forced
+ after ignition feed) and the dipped headlights have been switched on.
To cut off the + after ignition feed, proceed as follows:

disconnect the diagnostic tool,
press the Start button twice briefly (less than 3 seconds),
ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the instrument
panel have gone out.

Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of the faults should be taken into consideration when the diagnostic tool is used after
the + after ignition feed has been connected (with no action on the system components).
For a fault present, apply the procedure described in the section on the Interpretation of faults.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section 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 for these lines (for oxidation, bent pins, etc.),
the resistance of the component detected as defective,
the condition of the wires (melted or cut insulation, wear),
or use the fault finding procedure to check the circuit of the component at fault.
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because
the data is inconsistent. Therefore, this stage is used to:
run fault finding on faults that do not have a fault display, and 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 repairs.
This section gives 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 test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaints.
A summary of the overall procedure to follow is provided on the following page in

5. FAULT FINDING LOG
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 fault finding procedure,
ensures a record is kept of the procedure carried out. It is an essential document when
IMPORTANT consulting the manufacturer.
IT IS THEREFORE ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS
REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT.
You will always be asked for this log:

when requesting technical assistance from Techline,
when requesting approval before replacing parts for which approval is compulsory,
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
Safety rules must be observed during any work on a component to prevent any damage or injury:
check the battery voltage to avoid incorrect operation of computer functions.
During work on the airbag/seat belt pretensioner systems, it is essential that you lock the computer using
the diagnostic tool to prevent any risk of accidental triggering (all the trigger lines will be disabled).
The locked mode is indicated when the instrument panel warning light comes on.
If it is impossible to connect the diagnostic tool, switch off the ignition, remove the system power supply
fuse and wait at least 2 seconds for the discharge of the reserve power capacity.
Never measure the airbag or pretensioner trigger lines with any device other than XRBAG or CLIP's "Airbag
and pretensioner wiring harness check".
Before using a dummy ignition module, check to make sure that its resistance is between 1.8 et 2.5 .
During the procedure, check that the computer feed voltage does not drop below 10 V.
Disconnect the battery before removing and refitting any pyrotechnic component (airbag module,
pretensioner or seat belt retractor).
IMPORTANT
Airbag and pretensioner destruction and scrapping is subject to national legislation.

AIRBAG RC5
Vdiag: 14
Fault finding System operation 88C
The purpose of the air bag system RC5 P1/P2 is to provide optimum safety protection for all of the vehicle
occupants.
Special notes:
The MEGANE is equipped with driver and passenger seat belt buckle pretensioners in the front section.
The MEGANE is equipped with an "anti-submarine" airbag inside the seat base
The MEGANE is equipped with driver and passenger chest-level airbags in the rear section.
On MEGANE phase 1,
Warning light management: the status of the airbag fault warning light takes priority in relation to the status of
the passenger airbag warning light.
Impact management: a single level is emitted over the CAN line.
On MEGANE phase 2,
Warning light management: the two warning lights cannot be separated and the status of the passenger airbag
warning light is maintained when the airbag fault warning light illuminates.
Impact management: two levels of separate impacts are emitted over the CAN line.
Frontal impacts:
This function is performed entirely inside the computer. Accelerometers measure the violence of the impact. Vehicle
speed, driver's seat position, passenger airbag locking switching position and the accelerometer measurements
determine the strategy that the computer adopts to trigger the ignition modules. The front and rear seat belt inertia
reels, the front seat belt pretensioners, the face air bags (levels 1 and 2) can also be triggered or not according to the
entry parameters.
Side impacts:
This function is performed by the computer and the side impact sensors.
The position of the passenger airbag locking switch and the accelerometer measurements determine the strategy
that the computer adopts to trigger the ignition modules. The seat belt inertia reels, the seat belt pretensioners,
the front chest airbags and the curtain airbags thus may or may not be triggered.
Seat belt locking monitoring:

This function is performed by the instrument panel. The computer only sends the driver's seat belt buckle sensor
status. A warning light on the instrument panel is displayed if the driver is not wearing his seat belt, and a buzzer
reminds the driver of this when the vehicle speed exceeds 12 mph (20 km/h).
Inhibition of passenger trigger lines:

This function is performed by the computer and the passenger airbag locking switch.
The choice of whether or not to deactivate the passenger airbags must be made before the vehicle speed exceeds
0.3 mph (0.5 km/h). The computer measures an impedance (100 = Passenger Airbag deactivated;
400 = Passenger Airbag active). Above the threshold, any action on the locking switch results in storage of
the fault DF193 and the instrument panel warning light is illuminated.
The front passenger airbag (levels 1 and 2), the passenger lap belt pretensioner and the front passenger
chest-level airbag are deactivated when the locking switch is in the OFF position or when the fault
DF193 "Change of passenger airbag locking status" is present in the computer memory.
Monitoring the information displayed on the instrument panel:

The instrument panel controls the correct working of warning lights "air bag failure" and "air bag OFF" and informs
the air bag computer about possible warning light circuit failures through the multiplex network.

Fault finding Replacement of components 88C
REPLACING A SYSTEM COMPONENT
Disconnect the battery before removing and refitting any pyrotechnic component (airbag module,
pretensioner or seat belt retractor).
REPLACING THE AIRBAG COMPUTER

BEFORE REPLACING THE COMPUTER IT IS ESSENTIAL THAT YOU CONTACT THE TECHLINE.
To ensure that the returned computer's fault can be analysed, do not use command RZ001 "Fault memory"
when DF001 "Computer" is present or stored.
The airbag computers are sold in locked mode to avoid all risk of accidental triggering (all ignition lines are inhibited).
The "locked" mode is indicated when the airbag fault warning light on the instrument panel illuminates.
Follow this procedure to replace an airbag computer:

check that the ignition is switched off,
replace the computer,
modify the computer configuration if necessary,
write the VIN to the computer using the diagnostic tool command VP010 Write VIN,
switch off the ignition,
carry out a check using the diagnostic tool,
unlock the computer using the command VP007 Unlock computer, only if there are no faults declared by the
diagnostic tool and check that the warning light has gone out.
After the computer has been replaced, if there are abnormalities on the impact sensors, it is necessary to check that
the sensors fitted are compatible with the airbag computer connected to the vehicle. If not, it is necessary to order
the sensors which are specifically for the respective airbag.
