DESCRIPTION The ECM sends signals such as dynamic radar cruise control operation signals, brake operation demand signals and buzzer operation demand signals to the skid control ECU (brake actuator assembly) when the dynamic radar cruise control is operating. Therefore, if the skid control ECU (brake actuator assembly) detects a communication error with the ECM, it sends a malfunction signal back to the ECM.
CAUTION / NOTICE / HINT NOTICE:
