3 (BN) of CON4 like as
below?
Is the resistance value
of Fuse - Mlike as below?
Normal

Result
Is the resistance value of
heater like as below?
Is the resistance
value of DEF-sensor like
as below? It depends on
the temperature.
Explain to the customer!
: It can be occurred, when the gasket is not
stuck to product or when you put the high
temperature loads (hot foods) a lot
in the product.
