Using The M-MDS

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 2.0] ). Main relay (See RELAY INSPECTION ).

1. Connect the M-MDS to the DLC-2.
2. Switch the ignition ON.
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, FAN1, FAN3, FP, INJ_1, INJ_2, INJ_3, INJ_4, OIL_P_SOL, Test, VT EX_DES

PCM CONFIGURATION (USING READ/WRITE FUNCTION) [SKYACTIV-G 2.0]

Note. When performing configuration, it is necessary to read the vehicle specification information from the PCM before replacing it. Connect the M-MDS to the vehicle and perform vehicle identification before removing the PCM. The vehicle specification information is temporarily stored in the M-MDS.

1. Connect the M-MDS to the DLC-2.
2. After the vehicle is identified, select the following items from the initialization screen of the M-MDS. Select "Module Programming".
3. Then, select items from the screen menu in the following order. Select "Programmable Module Installation". Select "PCM".
4. Perform the configuration according to the directions on the screen. CAUTION: When the configuration is performed, CAN communication between the PCM and control module connected to the CAN line is cut temporarily, and communication error DTCs may be detected. After performing the configuration, verify the DTCs for the control module connected to the CAN line and clear it if any DTC is detected.
5. Verify the DTCs for all of the control modules connected to the CAN line. If any DTC is stored, clear it. If the DTC is cleared, finish the procedure because the configuration has been completed normally. If the DTC remains, perform troubleshooting according to the DTC.

PCM CONFIGURATION (USING AS-BUILT DATA) [SKYACTIV-G 2.0]

Note. If the configuration is performed using As-Built data, the set value of the personalization function is reset to the initial value (condition when shipped from factory). Verify the set value with the customer and perform the personalization function setting after performing the configuration using As-Built data.

1. Connect the M-MDS to the DLC-2.
2. After the vehicle is identified, select the following items from the initialization screen of the M-MDS. Select "Module Programming".
3. Then, select items from the screen menu in the following order. Select "As-Built". Select "PCM".
4. Perform the configuration according to the directions on the screen. CAUTION: When the configuration is performed, CAN communication between the PCM and control module connected to the CAN line is cut temporarily, and communication error DTCs may be detected. After performing the configuration, verify the DTCs for the control module connected to the CAN line and clear it if any DTC is detected.
5. Verify the DTCs for all of the control modules connected to the CAN line. If any DTC is stored, clear it. If the DTC is cleared, finish the procedure because the configuration has been completed normally. If the DTC remains, perform troubleshooting according to the DTC.

Scheme 86

1. Verify that the CPP switch is installed properly. (See «CLUTCH PEDAL POSITION SWITCH REMOVAL/INSTALLATION [C66M-R]»(ref-615414-S37439655452014051000000) ).

3. Disconnect the CPP switch connector.
4. Verify that the continuity between CPP switch terminals A and B when the clutch pedal is depressed and when it is released is according to the following table: If not as verified, replace the CPP switch. (See «CLUTCH PEDAL POSITION SWITCH REMOVAL/INSTALLATION [C66M-R]»(ref-615414-S37439655452014051000000) ). (Scheme 86): Identifying CPP Switch With Rod And Connector

2. Place the ECT sensor No.2 in water with a thermometer, and heat the water gradually. see scheme 51: Measuring ECT Sensor No.1 Temperature Using Thermometer
3. Measure the resistance between ECT sensor No.2 terminals A and B. If not as specified, replace the ECT sensor No.2. (See «ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0]»(ref-615396-S17600882762014051000000) ).
