CAUTION:

If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines (Refer to CAN BUS LINE DIAGNOSTIC FLOW ).
Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
When the hydraulic unit (integrated with ASC-ECU) is replaced, after turning the ignition switch ON and OFF (vehicle information from ETACS-ECU is registered), always perform the calibration of steering wheel sensor, G and yaw rate sensor, brake fluid pressure sensor, cut valve, and inlet valve (Refer to G AND YAW RATE SENSOR CALIBRATION , STEERING WHEEL SENSOR CALIBRATION , MASTER CYLINDER BRAKE FLUID PRESSURE SENSOR CALIBRATION , and CALIBRATION OF CUT VALVE AND INLET VALVE ).
When the ASC-ECU connector or battery terminal is disconnected with the ignition switch ON, this diagnostic trouble code may be set.
When this diagnostic trouble code is set, no other failure information will be set.
