PART REPLACEMENT AND KEY CODE REGISTRATION REQUIREMENTS
In the course of use, you may encounter the following cases where replacement of parts and regis-
tration of code re-registering/standard keys are required.
TIP
Each standard key is registered during production, therefore re-registering at purchase is not neces-
sary.
* Accessory locks mean the seat lock and fuel tank cap.
Code re-registering key registration:
When the immobilizer unit or ECU is replaced, the code re-registering key must be registered to the
unit.
To register a code re-registering key:
1. Set the main switch to “ON” with the code re-registering key.
TIP
Check that the immobilizer system indicator light comes on for one second, then goes off. When the
immobilizer system indicator light goes off, the code re-registering key has been registered.
2. Check that the engine can be started.
3. Register the standard key, following the instructions in the section below.
