4WD control module outputs the following signals to actuators, indicators, warning buzzer, according to the transfer
switch operation.
On-Board Diagnostic System Description
S5JB0A3311009
For 4WD control system, 4WD control module has the following functions.
• When ignition switch is turned ON with engine at stop, differential lock indicator (1), 4L indicator (2) and N indicator
(3) turn on at the same time for 2 seconds in order to check operation of these indicators.
• When 4WD control module detects any malfunction in the following area, differential lock indicator (1), 4L indicator
(2) and N indicator (3) flash continuously and 4WD control module comes into fail-safe mode. For details of fail safe
mode, refer to “Fail-Safe Table: Motor-Shift Type (Transfer with Shift Actuator)”.
– Transfer switch
– Transfer shift actuator motor
– Transfer shift actuator motor position switch
– 4L/N switch
– Center differential lock switch
