Although good
quality adblue emulators are quite easy to install and use, there are some
issues that may arise whilst installing it. Below we will discuss some of the
most common issues with certain truck makes and models.
Volvo EURO 6 FH, FM, FMX
If truck has SCR
related problems/error codes, before installing the emulator, most of them will
go away after installation. However, there is one error code in particular
which will stay. This is an error related to ‘poor AdBlue quality’ This is an
active error code which will not go away. This fault must be cleared/deleted
after installing the emulator using dealer level diagnostic tool such as VOLVO
VOCOM. Once this error code is cleared it will not come back and the emulator
will work fine. Please see photos below on how to clear this fault.

DAF LF45, DAF LF55 EURO 5
DAF LF EURO 5
models will require Can Smart Cummins emulator. This can be installed to a
vehicle with fully operational adblue system as well as to a vehicle with
existing adblue or nox related problems/faults. Our emulator will emulate both
– adblue system as well as nox sensors. If vehicle already had adblue faults
prior to installing the emulator, these will disappear after installation.
However, if there was an active nox fault it will stay even after installing
the emulator. Don’t worry, this is nothing serious. The vehicle needs to be
driven under load for a bit for this fault to clear by itself. This is due to
the fact that the truck’s ECU needs run tests and register correct signals sent
by the emulator. NOX tests are run at high temperature hence the vehicle must
be driven to achieve such conditions. Normally, active nox fault will disappear
after 20 – 50 miles of driving. You can also clear this fault with diagnostic
tool, but should you not have access to such tool simply driving the vehicle
will eliminate the fault.
Should you still
have adblue related faults after installing the emulator, please check adblue
tank level sensor and temperature sensor. These cannot be emulated and must be
in working condition. The adblue emulator covers all other SCR components.
Troubleshooting
DAF LF EURO 5
Can Smart Cummins
adblue emulator have self-diagnosis function. With emulator fully installed,
fuses taken out and ignition on, check the led lights on the emulator:
RED light = can
lines connected incorrectly
Action: check
instructions again to make sure you have made correct connections. If it seems right, swap can lines over and
check the light again.
RED/YELLOW light =
SCR system not disconnected
Action: Check
instructions again and make sure correct fuses are taken out.
Blue light =
emulator is fully operational.
SCANIA R730 EURO 5
Not all Scania
Euro 5 adblue emulators will work with this model. We do have bespoke emulator
for this vehicle, but please note it is important you quote this model when
ordering your emulator. We can also offer plug & play adblue emulator for
Scania R730 trucks.
MAN EURO 6 TGS, TGX, TGM, TGL
There are two
adblue emulators for MAN Euro 6 trucks. The only difference between them is a
slight difference in program/software. The difference is in adblue tank size.
Large trucks (TGX, TGS) will have large adblue tanks whilst smaller trucks
(TGM, TGL) will have a smaller tank. Emulator does need to be programmed for
the correct adblue tank size. If you have ordered emulator for TGS/TGX truck it
will not work on TGM/TGL trucks and vice versa. Please provide full vehicle
details when ordering to ensure we supply correct emulators.
SCANIA EURO 5 P, R, G
It is important to
mention that can line connections must be connected at the correct place
ensuring can line speed ability to receive and send signals from/to the ECU.
Unlike in most Euro 5 trucks where CAN-LINE connections can be taken from OBD
port, it is not the case with Scania trucks. CAN-LINES should be connected at
engine bay under the cab and extension routed back into the cab
This will ensure
optimum adblue emulator performance and longevity.
Please note,
CAN-LINE connections will be different for 6 and 8 cylinder engines. Please pay
particular attention to this part of instructions.
VOLVO FE, VOLVO FL EURO 6
If you have
installed the adblue emulator correctly, but it is not working, please check if
the vehicle is fitted with retarder. Our Volvo FL, FE adblue emulators are only
suitable for trucks without retarder at the moment.
