DESCRIPTION
The suspension control ECU receives signals from the ECM, four wheel drive control ECU, skid control ECU, yaw rate sensor, steering sensor, steering control ECU and main body ECU via CAN communication. When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.
