AWD-ECU
M22700000005USA0000010001
FUNCTION
The main functions of AWD-ECU are as follows:
Communication function
CAN communication with other ECUs (Engine
ECU, ASC-ECU, ETACS)
Communication with drive mode switch: The
signal from the drive mode switch changes the
drive mode.
Combination meter display: Drive mode is
displayed.
Coupling control function
Current output: Differential control function of
the electronic control coupling according to the
vehicle conditions
ECU self-diagnosis function
Initial check: ROM check, relay check, etc.
Recording function of diagnosis codes and
freeze frame data in case of failure
System shutdown function after failure
detection and AWD/LOCK indicator lamp
warning display function
Normal control: Malfunction of CPU power
supply, relay check, open or short circuit of the
I/O signal, abnormal CAN communication
FAIL-SAFE FUNCTION
FAILURE DETECTION
ECU performs the following checks at a timing shown
in the chart below. ECU determines the malfunction
occurred when the failure detection conditions are
met, and it sets the diagnostic trouble code and
executes the countermeasures for trouble. When the
failure resume conditions are met, ECU determines
the status is normal, and resumes the system.

CPU check
Performs the ROM and RAM check.
Actuator check
After CPU check has been completed, check
the driving voltage with the actuator relay OFF.

CPU check
Performs CAN communication and interactive
check between CPUs.
Power supply check
Monitors the CPU supply voltage and checks if
the voltage is within specifications.
Actuator check
Checks if the actuator relay turns ON according
to the control.
Compares the command current value from
CPU with the monitored current and checks if
they agree.
External wire connection check
Checks if the input and output of each external
wire connection is open, shorted, or stuck.
