SCR Cleaning - DeSOx Display Pop-up
In order that the SCR system may maintain its
exhaust cleaning efficiency at a proper level, it
should be periodically initialized—“SCR cleaning.”
NOTICE
Keep monitoring the vehicle condition via the
SCREEN display.
• At a workplace which is near inflammables or,
heavily populated, or an indoor space, disable the
SCR cleaning function.
• Be careful of the high temperature of the exhaust
tube or other parts during SCR cleaning.

Automatic SCR Cleaning
The ECU attempts to start SCR cleaning during
working—“automatic SCR cleaning”—at a proper
moment after determining the moment. Once
automatic SCR cleaning starts, the high temperature
indicator lamp lights up with a popup appearing for
the operator to notice it.
Display that notifies the operator of automatic SCR
cleaning
If automatic SCR cleaning is failed due to a low
exhaust temperature, you should perform it after the
vehicle stops. Therefore, it is recommended to keep
the vehicle working as far as possible in order to
ensure automatic SCR cleaning is fully completed.
While automatic SCR cleaning is being carried out,
exhaust emissions above 500 ℃ may cause fires or
burns.
