3) Ensure the steering wheel is in the central position and the front wheels are in the
straight position. Then tap
OK
to proceed.
4) When the operation is completed, the scan tool will display a confirmation message.
An error message will display if the procedure cannot be completed. Exit the
diagnosis program, and solve the error before attempting SAS calibration again.
Diesel Particle Filter (DPF) Service
The Diesel Particle Filter (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 high 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 diagnostic trouble code 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 diagnostics 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 correct spec 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 diagnostics log and read out relevant
measured value blocks.
