Using M-MDS

NOTE:

PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
- CMP sensor
- Main relay

Connect the M-MDS to the DLC-2.

Fig 1: Identifying DLC-2 Location
Switch the ignition to ON.

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
