Steering lock unit releases ignition knob rotation prohibition latch. (Ignition knob can now be turned.)
- When it becomes possible to rotate the ignition knob, "KEY" warning lamp in combination meter lights up green to notify driver that ignition knob can be turned.NOTE: When it becomes impossible to rotate the ignition knob, "KEY" warning lamp in combination meter lights up red.
- When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses CAN communication to send engine start permission signal to BCM.
- When BCM receives engine start permission signal, it uses CAN communication to sent starter request signal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
