Using M-MDS
NOTE:
- PIDs for the following parts are not available on this model. Go to the appropriate part inspection information.
- CMP sensor
- Main relay
- Connect the M-MDS to the DLC-2.
- Turn the ignition switch to the ON position.
- Measure the PID value.
- If PID value is not within the specification, follow the instructions in Action column.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, EVAPCP, EVAPCV, FAN_DUTY, FP, IMRC, IMTV, INJ_1~4, SEGRP, TEST, VT Duty1 wt
- If PID value is not within the specification, follow the instructions in Action column.
