Circuit Operation
Immobilizer control unit (ICU) permits engine starting, when the security code which compares the security code regis-
tered into the transponder (key) and the security code registered into ICU, and is similarly registered into ICU and engine
control unit (ECM) is compared and it is judged that it is normal. When the code registered into the key is unusual, and
when not recognizing a security code, ICU does not permit starting of engine.
