DTC Code DTC Name
U0101 Lost Communication with ECM
U0122 Lost Communication with Vehicle Dynamics Control Module
U0124 Lost Communication with Lateral Acceleration Sensor Module
U0126 Lost Communication with Steering Angle Sensor Module
U0130 Lost Communication with Steering Effort Control Module
U0132 Lost Communication with Suspension Control ECU
U0293 Lost Communication with HV ECU

DESCRIPTION

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