transmitter should be programmed. Up to 5 transmitters
can be provided with a scan tool (Tech-2) and by proper
procedure.
In addition to the absence of proper transmitter, it may
happen particular secret code to the particular vehicle is
missing. ln this case, the secret code must be provided
by your organization.
Otherwise transmitter cannot be programmed in any
way.
lf the essential for a scan tool (Tech-2) for programming
and proper software for Tech-2 are not available, there
is no permanent way to fix system. Temporary replace
with new ACU, new ICU and new transmitter without
any secret code can make the system be deactivated,
but it does not last long. Such a replacement does not
solve any condition. Even after replacement, the system
is activated automatically in short time and then no
operation of the vehicle can be made in any way.
Tech-2 should be provided in your organization.
