DTC U0100, U0101, U0122, U0124, U0126, U0130, U0132: Lost Communication with ECM/PCM "A"; Lost Communication with TCM; Lost Communication with Vehicle Dynamics Control Module; Lost Communication with Lateral Acceleration Sensor Module; Lost Communication with Steering Angle Sensor Module; Lost Communication with Steering Effort Control Module; Lost Communication with Suspension Control ECU: Description

The suspension control ECU inputs signals from the skid control ECU, steering control ECU, steering angle sensor, yaw rate & acceleration sensor, ECM and TCM via CAN communication. When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.
