1/ GENERAL INFORMATION
The engine immobiliser protection system is controlled by a RENAULT card recognition system with random rolling
code.
A coded transponder chip (operating without a battery) independent of the remote control function is built into each
of the vehicle's RENAULT Cards.
The engine immobiliser is active a few seconds after the RENAULT Card is removed from the card reader. Its status
is shown by the flashing warning light on the instrument panel and by locking of the steering column lock.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure.
There are two programming methods: "Not connected" to the code server mode and "connected" to the code
server mode.
–In the "not connected" mode, the CLIP diagnostic tool supplies a programming key and the user enters the
immobiliser code.
–In the "connected" mode, the CLIP diagnostic tool automatically exchanges the programming key and the
immobiliser code.
IMPORTANT
If not all of the Renault cards are available, reallocate all Renault cards later. Cards not inserted will no longer be
allocated to this vehicle.
IMPORTANT
In "not connected" mode, once the tool has issued the programming key, the user has a limited amount of time
in which to enter the immobiliser code.
If this time expires, the CLIP diagnostic tool displays the message "Time expired. Restart the procedure.
Note:
When only the UCH is replaced, there is no operation to perform on the injection computer or the steering column
lock, they retain the same immobiliser code.
IMPORTANT
Once a part is programmed with a code, it is allocated to the vehicle; the code cannot be deleted and the part
cannot be reprogrammed with another code. The programmed code cannot be erased.
IMPORTANT
In "connected" mode, the exchange of the programming key and the entry of the immobiliser code is done
automatically.
If the connection parameters are not met, "connected" mode switches automatically to "not connected" mode.

NOTESConditions for applying the fault finding procedure to a stored fault:
Insert the card into the card reader, switch on and switch off the engine leaving the
card in the card reader. Carry out fault finding on the card reader circuit with the card
in the card reader (after the engine is switched off, the card reader is supplied and
controlled for 20 min).
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
CC.0
NOTESNone.
Check the condition and connection of the card reader connector (tabs bent, broken, oxidised, etc.).
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the condition and connection of the PE2 and PE1 connectors of the UCH (tabs bent, broken, oxidised,
etc.).
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Ensure the continuity and insulation from earth of the following connections:
●Connection code 26BG,
●Connection code 26BD,
●Connection code 26BH.
Between components 645 and 1082.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Using the oscilloscope, check for a square pulse signal on connection 26BH of the card reader connector:
Connect the oscilloscope between connection 26BH of the connector and a bodywork earth.
Set the oscilloscope as: Calibration at 5 V/division
Time base 100 ms/division
Check for a square pulse signal from the UCH on connection 26BH of the card reader connector.
If there is no signal, replace the UCH.
If there is a signal, replace the card reader.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
