Using The M-MDS (SKYACTIV-G 1.3)

Note
• PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
― Intake CMP sensor and exhaust CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)
― Main relay (See RELAY INSPECTION.)

1.Connect the M-MDS to the DLC-2.

2.Switch the ignition ON (engine off).

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, ARPMDES, EVAPCP, FAN1, FAN3, FP, INJ_1, INJ_2, INJ_3, INJ_4, OIL_P_SOL

Using The M-MDS (SKYACTIV-G 1.5)

Note
• PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
― Intake CMP sensor and exhaust CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)
― Main relay (See RELAY INSPECTION.)

1.Connect the M-MDS to the DLC-2.

2.Switch the ignition ON (engine off).

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, ARPMDES, EVAPCP, FAN1, FAN2, FP, IMRC_DSD, INJ_1, INJ_2, INJ_3, INJ_4, OIL_P_SOL, Test
