System Wiring Diagram


Function Explanation (DTC Detection Outline)

•  The PCM performs malfunction determination of the PM sensor based on the PM temperature detected by the PM sensor. If the value detected by the PM sensor is not normal, the PCM stores a DTC.

Repeatability Verification Procedure

1.  Leave the vehicle for 6 hours or more.

2.  Start the engine and leave it idling for 30 min.

3.  Perform the “COMPULSORY DIESEL PARTICULATE FILTER REGENERATION”. (See COMPULSORY DIESEL PARTICULATE FILTER REGENERATION [SKYACTIV-D 1.8].)

4.  Drive the vehicle for 10 min at a speed of 100 km/h {62.1 mph} or less.

5.  Drive the vehicle for 10 min at a speed of 30 km/h {19 mph} or less.
