Starting and running
Reductant pump
When the reductant pump is new, the check
valves may need to be slackened.
Note:
There may be 2 reductant pumps: 1 located in the
reductant tank and 1 located between the main
tank for reductant and the buffer tank.
IMPORTANT!
Blow the reductant pump suction nipple with
compressed air (approx. 6 bar) for at least 3 sec-
onds before starting the engine for the first time.
Reset button on the reductant tank
The reductant tank has a reset button that can be
used, for example, when the tank is topped up for
the first time.
When the Scania EEC3 control unit checks fill-
ing, the following applies:
If you keep the button depressed for 5 sec-
onds, the reductant pump operates for 30 min-
utes. This function can be used, for example,
when the tank is topped up for the first time
or after cleaning.
If the reductant pump is operating and you
briefly press the button, the pump stops and a
fault code is generated.
The reductant pump can be restarted by
pressing the button, thus also making the
fault code passive.
If the level does not increase even though the
reductant pump is running, the pump is
switched off and a fault code is generated. If
you briefly press the button, the pump re-
starts.
