1. Connect the M-MDS to the DLC–2.
2. Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.5].)
If any DTC related to the ignition coil/ion sensor is present, repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [SKYACTIV-G 2.5].)
NOTE:
Because the ion sensor is integrated in the ignition coil, replacing the ion sensor includes replacement of the ignition coil/ion sensor.
1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)
2. Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
3. Remove the ignition coil/ion sensor. (See IGNITION COIL/ION SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
4. Verify that there is no damage to the ignition coil/ion sensor, and no corrosion and damage to the connector.
If there is a malfunction, replace the ignition coil/ion sensor. (See IGNITION COIL/ION SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
