Using The M-MDS
NOTE:
- PIDs for the following parts are not available on this model. Go to the appropriate part inspection.
- Intake CMP sensor and Exhaust CMP sensor Testing and Inspection
- Main relay Relay Inspection
1. Connect the M-MDS to the DLC-2.
2. Turn the ignition switch to the ON position.
3. 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, FAN_DUTY, FP, INJ_1, INJ_2, INJ_3, INJ_4, Test, VT EX_DES
