Ignition Antenna Unit (IAU)
Ignition antenna unit (IAU) is installed in the instrument panel beside the steering wheel.
The Ignition antenna unit (IAU) has an internal antenna that can be activated on command from the Central electronic module (CEM). The antenna is used for checking the key identity when the remote key is inserted in the ignition. The antenna is activated by the Central electronic module (CEM) when start button (IAU) is pushed.
The remote key does not need to be inserted in the ignition if there is a keyless vehicle module (KVM) in the vehicle. The identity of the remote key is then checked via the antennas in the passenger compartment instead. These antennas are connected to the keyless vehicle module (KVM) when start button (IAU) is pushed.
The Ignition antenna unit (IAU) is powered by the central electronic module (CEM) and grounded in the body.
