Scheme 49

Note. Within the following procedures, the term a "valid key" means a "key that can start the engine". After adding/registering keys, clearing ID numbers or replacing any component part of the immobilizer system, verify that all keys can start the engine within 5 s. When verifying that the keys can start the engine, wait at least 5 s or more between inserting them. If the engine cannot be started using a registered key, repeat the procedure from the beginning. Do not start the engine until the key registration procedure for all the necessary keys is completed. If the engine is started during the registration procedure, registration is stopped at that point. Repeat the procedure starting from the beginning if the engine is started before completion. Two or more key ID numbers must be registered for the engine to start. A maximum of eight key ID numbers can be registered for one vehicle. The WDS or equivalent can be used to verify the number of key ID numbers registered to a single vehicle. Do not select screen menus of the WDS or equivalent that are not indicated within the procedures.
