EC
When exhaust gas temperature reaches the specified value, oxidation catalyst is activated. The trapped par-
ticulate matter is burned through a catalytic reaction using exhaust gas heat at 600 °C.
During regeneration ECM performs a feedback control to keep emission levels low and burn particulate matter
safely and efficiently. This feedback control is performed based on the air fuel mixture ratio and the exhaust
gas temperature.
When performing regeneration, ECM raise the exhaust gas tempera-
ture to activate Oxidation Catalyst. If the vehicle is driven in the driv-
ing pattern in which the exhaust gas temperature can not be raised,
DPF warning light as shown in the figure lights up. DPF warning light
is located on combination meter.
When DPF warning light lights up, drive the vehicle under any of the
following condition to complete regeneration.
● The vehicle is driven continuously at 80km/h for 30 minutes*
● The vehicle is driven continuously 15km or more without being
caught in traffic jam
If the vehicle is driven in the driving pattern in which the exhaust gas
temperature can not be raised after DPF warning light lights up,
ECM performs the following to protect DPF.
● ECM enters fail-safe mode and limits engine speed to 2,000 rpm with fuel cut.
● ECM stores DTC P2002 in the memory.
To recover from the condition described above, perform “Service Regeneration” with CONSULT-II to reduce
the particulate matter through burning. Refer to EC-997, "
Service Regeneration" .
*: Always drive vehicle in safe manner according to traffic conditions and obey all traffic laws when driving.
Component Inspection BBS002M3
DPF
1. Check DPF for damage. If NG, go to 7.
2. Perform “Service Regeneration”. Refer to EC-997, "
Service Regeneration" .
3. Turn ignition switch ON.
4. Select “DATA MONITOR” mode with CONSULT-II.
5. Start engine and warm it up to normal operating temperature.
6. Check “DF EX PRES SE” signal under the following conditions.
7. If NG, replace oxidation catalyst with DPF.
8. Perform “DPF Data Clear”. Refer to EC-999, "
DPF Data Clear" .
