immobiliserINACTIVE
Indicates the status of the
immobiliser system.
INACTIVE: The injection computer
has recognised the immobiliser code
transmitted by the UCH.
ACTIVE: The injection computer
does not recognise the immobiliser
code transmitted by the UCH.If status ET003 is
inconsistent, consult the
fault finding procedure for
the UCH (See 82D,
Access – Security).
Air

conditioningYES - NO
States whether the vehicle is fitted
with air conditioning or not.
YES: Air conditioning is detected by
the injection computer.
NO: Air conditioning is not detected
by the injection computer.If not consistent with the
vehicle equipment, test the
multiplex network and
follow the relevant
procedure.
Fast idle speedET023:Fast idle speed
requestABSENT
The UCH sends a fast idle request to
the injection.
ABSENT: no UCH request.
PRESENT: UCH request.If status ET023 is
inconsistent, consult the
fault finding procedure for
the UCH (See 87B,
