System Component And Function

WARNING: This page is about a different variant/trim than selected.
SYSTEM COMPONENT AND FUNCTION CHART

Parts name Functional description
Engine control module Sends the following signals required by AWD-ECU via CAN communication.
  • Engine torque signal
  • Throttle position signal
  • Engine speed signal
ABS/ASC-ECU Sends the following signals required by AWD-ECU via CAN communication.
  • ABS sensor signal (wheel speed signal) [4 wheels]
  • ABS operation signal
  • AWD limitation torque signal
Drive mode selector Sends the drive mode switch signal [FWD/AWD/LOCK] to AWD-ECU.
ETACS-ECU
  • Receives the drive mode switch signal [FWD/AWD/LOCK] from AWD-ECU and flashes the indicators (AWD operation indicator and LOCK indicator) in the combination meter.
  • Flashes the indicators (AWD operation indicator and LOCK indicator) in the combination meter in case of failure.
Controls diagnostic function (Compatible with scan tool).
AWD-ECU Calculates the optimum differential limitation force judging from the vehicle condition and present drive mode based on the signals from each ECU and switch, and controls the current value flown to the electronic control coupling.
Controls the indicators (AWD operation indicator and LOCK indicator) in the combination meter.
Controls the self-diagnostic function and fail-safe function.
Controls diagnostic function (Compatible with scan tool).
Electronic control coupling Transmits the torque corresponding to the current value controlled by AWD-ECU to the rear wheels.
Drive mode indicator
  • AWD operation indicator
  • LOCK indicator
 Integrated in the combination meter, and indicates the selected drive mode (Not displayed in FWD mode).
  • When the AWD operation indicator and LOCK indicator flash alternately, the system automatically enters the front wheel drive mode to protect the drive system components, and the drive mode changeover with the drive mode selector becomes unavailable.
  • When the drive system generates heat, the AWD operation indicator flashes.
  • The indicator light operation signal from AWD-ECU is sent to the combination meter via ETACS-ECU using CAN communication.
Data link connector Outputs the diagnostic trouble code and establishes the communication with scan tool.
