NOTE
1.
This function is not supported by all vehicles.
2.
The sub functions and actual test screens of the BMS may vary by vehicle. Please follow
the on-screen instructions to make correct selection.
The vehicle may use either a sealed lead-acid battery or an Absorbed Glass Mat (AGM)
battery. Lead acid batteries contain liquid sulphuric acid and can spill when overturned. AGM
batteries (valve regulated lead acid, VRLA batteries) also contains sulphuric acid, but the acid
is contained in glass mats between terminal plates.
It is recommended that the replacement aftermarket battery has the same specifications, such
as capacity and type, as the original battery. If the original battery is replaced with a different
type of battery (e.g., a lead-acid battery is replaced with an AGM battery) or a battery with a
different capacity (mAh), the vehicle may require reprogramming of the new battery in addition
to performing the battery reset. Consult the vehicle manual for additional vehicle-specific
information.
10.5 Diesel Particle Filter (DPF) Service
The DPF function manages DPF regeneration, DPF component replacement teach-in and
DPF teach-in after replacing the engine control unit.
The ECM monitors driving style and selects a suitable time to employ regeneration. Cars
driven a lot at idling speed and low load will attempt to regenerate earlier than cars driven
more with higher load and speed. In order for regeneration to take place, a prolonged high
exhaust temperature must be obtained.
In the event of the car being driven in such a way that regeneration is not possible, i.e.,
frequent short journeys, a DTC will eventually be registered in addition to the DPF light and
“Check Engine” indicators. A service regeneration can be requested in the workshop using
the diagnostic tool.
Before performing a forced DPF regeneration using the tool, check the following items:
The fuel light is not on.
No DPF-relevant faults are stored in system.
The vehicle has the specified engine oil.
The oil for diesel is not contaminated.
IMPORTANT
Before diagnosing a problem vehicle and attempting to perform an emergency regeneration,
it is important to obtain a full diagnostic log and read out relevant measured value blocks.
