ET003ENGINE IMMOBILISER
STATUS DEFINITIONACTIVE: This status indicates that the immobiliser is active.
INACTIVE: This status indicates that the immobiliser is inactive.
NOTESACTIVE: ET003 "ENGINE IMMOBILISER" shows the vehicle protection status.
This Verlog 4 type immobiliser function is managed by the UCH computer and the
injection computer.
Before any starting request, the computer is protected.
When a starting request is made, the injection computer and the UCH exchange
authentication data via the multiplex network. This determines whether the engine start
is authorised or denied.
After more than 5 consecutive failed authentication attempts, the injection computer
goes into protection (anti-scanning) mode and no longer tries to authenticate the UCH
computer.
It only leaves this mode when the following sequence of operations is carried out:
–The ignition is left on for at least 5 seconds,
–The ignition is switched off,
–The injection computer self-supply cuts out when it should (the time varies according
to engine coolant temperature).
Conformity check: Engine stopped, ignition on or engine running.
"ACTIVE"If status ET003 is ACTIVE, see 82A, Engine immobiliser.
"INACTIVE"When the ignition is switched on and when driving, status ET003 should be INACTIVE,
if this is not the case, see 82A, Engine immobiliser.

ET006CODE PROGRAMMED
STATUS DEFINITIONYES: This status indicates that the immobiliser code has been programmed.
NO: This status indicates that the immobiliser code has not been programmed.
NOTESThe injection immobiliser code is not written in the injection computer.
The programming of this code in the injection computer is managed by the UCH.
To carry out programming:
–establish communication with the UCH see 87B, Passenger compartment
connection unit.
–run command SC017 Program injection immobiliser code,
–follow the instructions for the procedure.
As long as this phase has not been completed, ET006 "Code programmed" is "NO".
IMPORTANT:
the immobiliser code is written in the injection computer memory at the end of the
computer auto-feed phase. Do not disconnect the battery before the end of this phase.
Conformity check: Engine stopped, ignition on or engine running.
YESStatus ET006 is YES if dialogue is possible between the UCH computer and the injection
computer and the key code is recognised.
The engine is only authorised to start if the code is recognised by the UCH computer and
if status ET003 Immobiliser is INACTIVE.
In the event of a fault, (see 87B, Passenger compartment connection unit,
conformity check).
