If the verification result is OK, the engine can start. If the verification result is NG, the engine can not start.
IPDM E/RINFOID:0000000009461069
IPDM E/R has the starter relay and starter control relay inside. Starter relay and starter control relay are used
for the engine starting function. IPDM E/R contro ls these relays while communicating with BCM.
NATS Antenna Amp.INFOID:0000000009461070
The ID verification is performed between BCM and transponder in Intelligent Key via NATS antenna amp.
when Intelligent Key backside is contacted to push-button i gnition switch in case that Intelligent Key battery is
discharged. If the ID verification result is OK, the operation of starting engine is available.
TCMINFOID:0000000009461071
TCM transmits the shift position signal (P/N position) to BCM and IPDM E/R. And further, TCM transmits the
shift position signal (P/N position) to BCM via CAN communication.
BCM confirms the CVT shift selector position with the following 5 signals:
• P (Park) position signal from CVT shift selector (park position switch)
• P/N position signal from TCM
• P (Park) position signal from IPDM E/R (CAN)
• P/N position signal from IPDM E/R (CAN)
• P/N position signal from TCM (CAN)
IPDM E/R confirms the CVT shift select or position with the following 3 signals:
• P (Park) position signal from CVT shift selector (park position switch)
• P/N position signal from TCM
• P/N position signal from BCM (CAN)
Combination MeterINFOID:0000000009461072
Combination meter transmits the vehicle speed signal to BCM via CAN communication.
BCM also receives the vehicle speed signal from ABS ac tuator and electric unit (control unit) via CAN commu-
nication. BCM compares both signals to detect the vehicle speed.
Door SwitchINFOID:0000000009461073
Door switch detects door open/close conditi on and then transmits ON/OFF signal to BCM.
Outside Key AntennaINFOID:0000000009461074
Outside key antenna detects whether Intelligent Key is outside the vehicle and transmits the signal to BCM.
Three outside key antennas are installed in the front outside handle LH, front outside handle RH and rear
bumper.
Hood SwitchINFOID:0000000009461075
Hood switch detects that hood is open/closed, and then trans mits the signal to IPDM E/R. IPDM E/R transmits
hood switch signal to BCM via CAN communication.
Inside Key AntennaINFOID:0000000009461076
Inside key antenna detects whether Intelligent Key is inside the vehicle and transmits the signal to BCM.
Two inside key antennas are installed in the front console and rear parcel shelf.
Remote Keyless Entry ReceiverINFOID:0000000009461077
Remote keyless entry receiver receives each button oper ation signal and electronic key ID signal from Intelli-
gent Key and then transmits the signal to BCM.
Intelligent KeyINFOID:0000000009461078
Each Intelligent Key has an individual electronic ID and transmits the ID signal by request from BCM.
Carrying the Intelligent Key whose ID is registered in BCM, the driver can perform, remote start, door lock/
unlock operation, remote trunk, panic alarm and push-button ignition switch operation.
