Registration of the Ignition Key

To finish the registration of the ignition key, the
transponder code memorized in the transponder built in
the ignition key has to be registered with ECM. To
register the transponder code with ECM, perform
"Immobilizer Key Registration" mode of SUZUKI scan
tool referring to "SUZUKI scan tool Operator's Manual".
NOTE
• A maximum of four transponder codes can
be registered with ECM.
• At an early part of the registration process,
all transponder codes of the ignition keys
in use already registered with ECM are
cleared. Therefore, before starting the
registration, prepare all ignition keys in
use in addition to the new ignition key(s) to
be registered with ECM.

Procedure after ECM Replacement

After ECM is replaced with new one or used one, the
transponder code in the transponder built in the ignition
key has to be registered with ECM. To register
transponder code in the ignition key with ECM, perform
"Immobilizer Key Registration" mode of SUZUKI scan
tool referring to "SUZUKI scan tool Operator's Manual".
NOTE
A maximum of four transponder codes can
be registered with ECM.
