SYSTEM DESCRIPTION

The engine immobilizer system has been designed to prevent the vehicle from being stolen.

This system uses a transponder key ECU that stores the key code of the authorized ignition key. If an attempt is made to start the engine using a non-authorized key, the transponder key ECU sends a signal to the hybrid vehicle control ECU to prohibit fuel delivery and ignition, effectively disabling the engine.
