Engine Immobiliser System; Operating Principle - Renault Sandero Handbook

ENGINE IMMOBILISER
This prevents the vehicle being
driven by anyone not in possession
of the vehicle's coded ignition key.

Operating principle

The vehicle is automatically protected
a few seconds after the ignition is
switched off.
If the vehicle does not recognise the
coded ignition key, tell-tale light 1 will
flash continuously and the engine
cannot be started.
Any unauthorised work
carried out on the engine
immobiliser (computers,
wiring, etc.) could be dan-
gerous. Work must be carried out
by qualified personnel.

System operation
When the ignition is switched on, tell-
tale 1 lights up continuously for approx-
imately three seconds and then goes
out. The vehicle has recognised the
code. You can then start the engine.
Vehicle protection
A few seconds after the ignition has
been switched off, tell-tale light 1 will
flash constantly.
The vehicle will only be protected after
the ignition has been switched off.
Operating faults
After the ignition has been switched
on, if warning light 1 continues to flash
or remains continuously lit, there is a
system operating fault.
In all cases, it is essential to contact
an approved dealer as only they are
qualified to repair the engine immobi-
liser.
If the coded ignition key is faulty,
use the second key (supplied with
the vehicle).
