Part Description
BCM Controls the exterior lighting system.
ECM*
1Transmits engine speed signal to AFS control unit. (via CAN communication)
TCM*
1Transmits Shift position signal to AFS control unit. (via CAN communication)
IPDM E/R Controls the integrated relay, and supplies voltage to the load according to the request
from BCM (via CAN communication).
AFS control unit*
1AFS control unit judges the vehicle condition from each signal. AFS control unit con-
trols AFS function and the headlamp aiming.
Combination meter  Outputs the vehicle speed signal (8-pulse) to AFS control unit.
 Blinks the turn signal indicator lamp and outputs the turn signal operating sound with
integrated buzzer according to the request from BCM (via CAN communication).
 Turns the tail lamp indicator lamp and high beam indicator lamp ON according to the
request from BCM (via CAN communication).
 Turns the AFS OFF indicator lamp ON/OFF /blinking according to the request from
AFS control unit (via CAN communication).

1Refer to EXL-9, "FRONT COMBINATION LAMP : Swivel Actuator".
Height sensor*
1
 The height sensor is installed to the front suspension member and rear suspension member.
 The height sensor detects the suspension arm displacement as the vehicle height change.
 The height sensor transmits the height sensor signal to AFS control unit.
NOTE:
The sensor angle of the unloaded vehicle position is the reference value.
Optical sensor Optical sensor converts the outside brightness (lux) to voltage and transmits the opti-
cal sensor signal to BCM.
