System Wiring Diagram

•  Not applicable

Function Explanation (DTC Detection Outline)

•  The PCM monitors the filter function condition of the catalytic converter (diesel particulate filter) based on the PM sensor signal. When the PM sensor current is not within the threshold value continuously, the PCM determines that the filter function of the catalytic converter (diesel particulate filter) decreases, and stores a DTC.

Repeatability Verification Procedure

Caution
•  When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.
•  While performing this step, always operate the vehicle in a safe and lawful manner.
Note
•  If the diesel particulate filter (catalyst converter) is replaced as a result of the diagnosis, perform the procedure from Step 3.

1.  Perform the "COMPULSORY DIESEL PARTICULATE FILTER REGENERATION". (See COMPULSORY DIESEL PARTICULATE FILTER REGENERATION [SKYACTIV-D 1.8].)

2.  Stop the engine and leave for 1 hour or more.

3.  Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC.)

4.  After starting the engine, drive the vehicle for approx. 30 km {19 mile} and warm up the engine.

5.  Release the accelerator pedal and decelerate the vehicle for 5 s or more, after rapidly accelerate the vehicle to 120 km/h {74.6 mph}.

6.  Repeat Step 5 operation above 2 times.
