IMMOBILIZER SYSTEMCOMPONENTS LAYOUTOUTLINEThis system consists of a transponder-built-in key, an antenna coil, an immobilizer ECU and EFI ECU.In the immobilizer system for EFI gasoline engine, if the key ID code can not be collated or the rolling codeis not matched with each other, the EFI ECU stops the ignition and fuel injection, thereby stopping the en-gine operation. The key ID code is a transponder intrinsic code, whereas the rolling code takes a differentvalue every time the engine is started. This code is renewed and memorized in the EFI ECU and immobiliz-er ECU as the rolling code for the next starting.BE–91EFI ECUImmobilizer ECUJBE00327-06001JBE00328-06002
