No. Component Function
WHITE-1 Trunk lid lock assembly (trunk room lamp switch) Trunk room lamp switch is integrated into trunk lid lock assembly.
Trunk room lamp switch detects trunk lid open/close condition and then transmits ON/OFF signal to BCM.
WHITE-2 Outside key antenna (rear bumper) Outside key antenna detects whether Intelligent Key is within the detection area or not, and then transmits signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-3 Inside key antenna (trunk room) Inside key antenna (trunk room) detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-4 Outside handle assembly (passenger side) One touch unlock sensor One touch unlock sensor detects user hold outside handle operation and transmits one touch unlock sensor signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
Door request switch Door request switch (passenger side) detected door lock/unlock operation and transmits door request switch signal to BCM.
WHITE-5 Door switch (passenger side) Door switch (passenger side) detects door open/close condition and then transmits ON/OFF signal to BCM.
WHITE-6 Inside key antenna (console) Inside key antenna (console) detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-7 Remote keyless entry receiver Remote keyless entry receiver receives each button operation signal and electronic key ID signal from Intelligent Key, and then transmits the signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-8 BCM BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION), INFINITI VEHICLE IMMOBILIZER SYSTEM (NATS) and VEHICLE SECURITY SYSTEM.
BCM performs the ID verification between BCM and Intelligent Key when the Intelligent Key is carried into the detection area of inside key antenna, and push-button ignition switch is pressed.
If the ID verification result is OK, ignition switch operation is available.
Then, when the ignition switch is turned ON, BCM performs ID verification between BCM and ECM.
If the ID verification result is OK, ECM can start engine.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-9 IPDM E/R Starter control relay and starter relay are integrated in IPDM E/R, and used for the engine starting function.
Starter relay is controlled by BCM, and starter control relay is controlled by IPDM E/R while communicating with BCM.
IPDM E/R sends the starter control relay and starter relay status signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-10 Inside key antenna (instrument lower) Inside key antenna (instrument lower) detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-11 Horn low Horn low operate for warning vehicle surroundings when VEHICLE SECURITY SYSTEM operates.
WHITE-12 ECM*1 ECM controls the engine.
When ignition switch is turned ON, BCM starts communication with ECM and performs the ID verification between BCM and ECM.
If the verification result is OK, the engine can start.
If the verification result is NG, the engine cannot start.
Refer to COMPONENT LOCATION (VR30DDTT engine models) for detailed installation location.
WHITE-13 Horn high Horn high operate for warning vehicle surroundings when VEHICLE SECURITY SYSTEM operates.
WHITE-14 A/T assembly (TCM) TCM detects the selector lever position, and then transmits the P/N position signal to BCM and IPDM E/R (VR30DDTT engine models) or ECM (2.0L turbo gasoline engine models).
BCM confirms the A/T shift selector position with the following 4 signals.
  • P position signal from A/T shift selector (detention switch)
  • P/N position signal from TCM
  • Interlock/PNP switch signal from IPDM E/R (CAN)
  • P/N position signal from TCM (CAN)

IPDM E/R confirms the A/T shift selector position with the following 3 signals.
  • P position signal from A/T shift selector (detention switch)
  • P/N position signal from TCM
  • P/N position signal from BCM (CAN)

Refer to COMPONENT LOCATION for detailed installation location.
WHITE-15 Hood switch Refer to HOOD SWITCH .
WHITE-16 ECM*2 ECM controls the engine.
When ignition switch is turned ON, BCM starts communication with ECM and performs the ID verification between BCM and ECM.
If the verification result is OK, the engine can start.
If the verification result is NG, the engine cannot start.
ECM transmits the P/N position signal to BCM via CAN communication.
Refer to COMPONENT LOCATION (2.0L Turbo gasoline engine models).
WHITE-17 ABS actuator and electric unit (control unit) ABS actuator and electric unit (control unit) transmits the vehicle speed signal to BCM via CAN communication.
BCM also receives the vehicle speed signal from combination meter via CAN communication.
BCM compares both signals to detect the vehicle speed.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-18 Stop lamp switch Stop lamp switch detects that brake pedal is depressed, and then transmits ON/OFF signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-19 TCU TCU transmits engine start signal to BCM when engine start request signal is received from Infiniti Connection™ data center.
Refer to COMPONENT LOCATION for detailed installation location.
WHITE-20 Power window main switch (door lock and unlock switch) Door lock and unlock switch transmits door lock/unlock signal operation to BCM.
CIRCLE WHITE-21 Combination meter Combination meter transmits the vehicle speed signal to BCM via CAN communication.
BCM also receives the vehicle speed signal from ABS actuator and electric unit (control unit) via CAN communication.
BCM compares both signals to detect the vehicle speed.
Security indicator lamp is located on combination meter.
Security indicator lamp blinks when ignition switch is in any position other than ON to warn that INFINITI VEHICLE IMMOBILIZER SYSTEM (NATS) is on board.
CIRCLE WHITE-22 Outside handle assembly (driver side) One touch unlock sensor One touch unlock sensor detects user hold outside handle operation and transmits one touch unlock sensor signal to BCM.
Refer to COMPONENT LOCATION for detailed installation location.
Door request switch Door request switch (driver side) detected door lock/unlock operation and transmits door request switch signal to BCM.
CIRCLE WHITE-23 Door switch (driver side) Door switch (driver side) detects door open/close condition and then transmits ON/OFF signal to BCM.
CIRCLE WHITE-24 A/T shift selector (detention switch) Detention switch is integrated into A/T shift sector, and detects that selector lever is locked in the P position, then transmits ON/OFF signal to BCM and IPDM E/R.
CIRCLE WHITE-25 Trunk lid opener request switch Trunk lid opener request switch detects open operation of trunk lid and transmits trunk lid opener request signal to BCM.
CIRCLE WHITE-26 Push-button ignition switch Push-button ignition switch has push switch inside which detects that push-button ignition switch is pressed, and then transmits ON/OFF signal to BCM.
BCM change the ignition switch position with the operation of push-button ignition switch.
BCM maintains the ignition switch position status while push-button ignition switch is not operated.
CIRCLE WHITE-27 NATS antenna amp. Refer to NATS ANTENNA AMP. .
