Reaction to fault in the exhaust gas after-
treatment system – EU Stage V/China IV
The symbol and behaviour of the warning lamp
depend on the installation of the engine in the
machine. The Scania recommendation will lead
to the behaviour and symbol described here, but
this may differ between different machines.
Once the fault has been remedied and the engine
management system has received an indication
that the exhaust gas aftertreatment system is op-
erational, i.e. when the fault code has been ac-
knowledged in SDP3, torque returns to the
normal level.
