1 - Immobiliser code
The computers are supplied uncoded. When a com-
puter is replaced it must be programmed with the ve-
hicle code, and checked to ensure that the
immobiliser function is working properly.
Switch on the ignition for a few seconds then switch
it off.
Check the condition of the computer (coded or not
coded) using the diagnostic tool:
- if the state ET099 «
Immobiliser code
programmed » is inactive, this means that the in-
jection computer is not coded.
- if the state ET002 « Immobiliser » is active, star-
ting the engine is impossible.
2 - Programming
Perform flywheel target programming during a road
test:
- a deceleration with injection cut-off in second, third,
fourth or fifth gear between 3,500 and 3,000 rpm,
for at least 2 seconds,
- make a second deceleration with injection cut-off in
second, third, fourth or fifth gear between 2,400
and 2,000 rpm for at least 3 seconds.
Using the diagnostic tool, check that this program-
ming is properly done, ET060 « Flywheel signal
with engine running ».
Read the fault codes.
Repair if necessary.
Clear the fault codes.
WARNING
- The injection computer retains the immobiliser
code for life.
- The system has no security code.
- Running tests with computers borrowed from
the Parts Department or from another vehicle
which must then be returned is prohibited.
These computers are permanently coded.
