The EIS serves as the "brain" of the security system. It shops information tracks for as much as 8 secrets. When a key is inserted (or the Start button is pressed), a handshake happens. The EIS sends an infrared signal to the key, the key procedures that signify utilizing a proprietary algorithm, and it sends a response back. If the mathematics matches, the ESL (Electronic Steering Lock) releases, and the engine is permitted to crank.
The Programming Process
An expert service normally follows these steps:
