Immobilizer Antenna Unit (IAU)

The Immobilizer Antenna Unit (IAU) is used if the Keyless Vehicle Module (KVM) is unable to authorize the smart key. If the KVM is unable to identify the smart key, for example if the smart key battery voltage is low or there is local Radio Frequency (RF) interference, the transponder within the smart key can be read in the conventional manner. The driver will be alerted to this by a chime and a message in the IC message center 'SMART KEY NOT FOUND POSITION AS SHOWN AND PRESS START BUTTON.
