note	^*: The service data which begins with A or B must be used when the steering has become heavy without setting any diagnostic trouble code. If assist functions are not intervened or the battery voltage is not dropped, the scan tool (M.U.T.-IIISE) displays an abnormal value. But there is no fault.

When the EPS-ECU shut off electric power steering system operation.

When the diagnosis system stops the EPS-ECU, the scan tool (M.U.T.-IIISE) display data will be unreliable.
