Using The M-MDS

NOTE:

PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
- CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION .)
- Main relay (See RELAY INSPECTION .)

Connect the M-MDS to the DLC-2.

Fig 1: Identifying 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.
- The simulation items that are used in the ENGINE CONTROL SYSTEM OPERATION INSPECTION are as follows.
  - ACCS, ALTF, ARPMDES, EVAPCP, EVAPCV, FAN1, FAN2, FP, IMRC, INJ_1, INJ_2, INJ_3, INJ_4, SEGRP, Test, VT Duty1 wt
