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 option selection.
The vehicle may use either a sealed lead-acid battery or an Absorbed Glass Mat (AGM)
battery. Lead acid battery contains liquid sulphuric acid and can spill when overturned.
AGM battery (known as VRLA battery, valve regulated lead acid) 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 exiting 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 type, in addition to, performing the battery reset. Consult the vehicle manual
for additional vehicle-specific information.
5.5 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 displaying. 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.
