 id0140s1538300


DTC Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Perform the KOEO self test.

3.  Perform the DTC inspection using the M-MDS. (See DTC INSPECTION.)

•  If any DTC related to the exhaust shutter valve position sensor is present, repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D)].)

Note
•  The exhaust shutter valve position sensor is built into the exhaust shutter valve actuator. When replacing the exhaust shutter valve position sensor, replace the exhaust shutter valve actuator.

PID/DATA Monitor Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine off).

3.  Access and monitor the PID/DATA monitor item EX_SHUT_VLV_ACT and simulation item EX_SHUT_VLV_DSD. (See PID/DATA MONITOR INSPECTION.)(See SIMULATION INSPECTION.)

4.  Verify that the EX_SHUT_VLV_ACT PID value increases linearly, while increasing the opening angle of the exhaust shutter valve using the active command mode function of EX_SHUT_VLV_DSD.

•  If the EX_SHUT_VLV_ACT PID does not increase according to the exhaust shutter valve opening angle, inspect the exhaust shutter valve.
(See EXHAUST SHUTTER VALVE INSPECTION [SKYACTIV-D 1.8].)
•  If the EX_SHUT_VLV_ACT PID increases increase linearly according to the exhaust shutter valve opening angle, the exhaust shutter valve is normal.
