ET341IMMOBILISER CODE 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.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
YESStatus ET341 is YES if dialogue is possible between the UCH computer and the
injection computer and if the key code is recognised.
Engine starting authorisation is only given if the code is correctly recognised by the
UCH computer and status ET003: Engine immobiliser is INACTIVE.
In the event of a fault (see 87B, passenger compartment connection unit,
conformity check).
NOStatus ET341 is NO if dialogue is not possible between the UCH computer and the
injection computer (status ET003 Engine immobiliser remains ACTIVE).
This fault may be caused by incorrect key programming or a lack of key programming.
In this case, refer to the UCH fault-finding note (see 87B, Passenger compartment
connection unit) and follow the key programming procedure.
If the key programming is not the cause, run a multiplex network test (see 88B,
Multiplexing) and check that dialogue between the UCH and the injection computer
is possible.
If dialogue is not established, contact Techline.
