    Note: ① For the anti-theft ECU and the engine ECU collection as one of the device (ECU), regardless of models, such ignition key registration methods are applicable. ② the ignition key registration order: 1 main ignition key, 2 main ignition key, 3 sub-ignition key. If the registration order of the ignition key is changed, it can not be registered normally. ③ If you do not follow the correct registration method, will cause the engine ECU only to identify an ignition key, that is, the first to insert the ignition switch ignition key, so that the other two can not start the engine.
