    NOTE:
    • The PID/DATA MONITOR function monitors the calculated value of the input/output signals in the PCM. Therefore, an output device malfunction is not directly indicated as a malfunction of the monitored value for the output device. If a monitored value of an output device is out of specification, inspect the monitored value of the input device related to the output control.
    • For input/output signals except those of the monitoring items, use a voltmeter to measure the PCM terminal voltage.
    • The simulation items that are used in the ENGINE CONTROL SYSTEM OPERATION INSPECTION are as follows.
      • ACCS, ALTF, ARPMDES, ETC_DSD, EVAPCP, FAN1, FAN2, FAN3, FP, FUELPW1, GENVDSD, HTR11, HTR12, IAC, IASV, IMRC, IMTV, INJ_1, INJ_22, INJ_3, INJ_4, SEGRP, test, VT DUTY1
