- Since the Active torque control system (4WD control system) may be influenced by a malfunction in other systems, be sure to check for DTCs in the other systems.
- When removing and installing the 4WD control ECU and each sensor, be sure to check that the normal display is output in test mode inspection and in DTC output inspection after installing all the parts.
- If the DTC of the CAN communication line is output, repair the malfunction in the communication line and troubleshoot the 4WD control system.
- Since the CAN communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.
- When the 4WD control ECU is replaced with a normal one from another vehicle, or the yaw rate sensor is replaced, be sure to perform calibration.
