Immobilizer System Registration
Immobilizer System Registration
This process closely resembles the procedure
currently used for type “A” Immobilizer systems.
Execute Immobilizer
New and old keys are registered with this
selection. Use this selection when adding
new keys (old keys must first be deleted), and
when the BIU is replaced. (RES must also be
registered using separate selection).
Registering Each Key
This screen displays as the Immobilizer is
registering each key.
If this process is accidentally exited before
completion of the first key, no key will start the
vehicle. (No DTCs will be created)
Correction to this condition is performed by the
following:
1. Turning off the ignition and remove the
key.
2. Wait for about 1 minute with the door
open.
3. After one minute the BIU will enter
sleep mode and click can heard from
underneath the steering wheel.
4. Begin the Immobilizer system registration
from the beginning.
5. Test all keys for engine start after
completion.
