Operation When Ignition Key Is Inserted Into Ignition Key Cylinder

  1. When ignition switch is turned ON, BCM activates NATS antenna amp. to start NVIS(NATS) ID verification with the ignition key (transponder is integrated).
  2. BCM receives the NVIS(NATS) ID signal from ignition key via NATS antenna amp. and verifies it with the registered ID.
  3. When the NATS ID verification result is OK, BCM performs the ID verification between BCM and ECM.
  4. When the verification result is OK, BCM transmits the verification OK signal to ECM, and then ECM can start the engine.
  5. When the ignition switch is turned to the START position, BCM transmits the starter request signal to IPDM E/R.
