DTC U0100/56, U0122/56, U0123/56, U0126/56, U0131/56: Lost Communication with ECM/PCM "A"; Lost Communication with Vehicle Dynamics Control Module; Lost Communication with Yaw Rate (Deceleration) Sensor Module; Lost Communication with Steering Angle Sensor Module; Lost Communication with Power Steering Control Module: Description
The steering control ECU receives signals from the skid control ECU, yaw rate (deceleration) sensor, steering angle sensor and power steering ECU via CAN communication. When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.
