This function is used to clean the particle filter. The function lasts for at least 30 minutes depending on the coolant temperature. Never disconnect the tester when regeneration is in progress. Never move the vehicle during regeneration. Do not press down the brake pedal. Never perform more than two regenerations in a row. Otherwise the engine may be damaged.
Note:
Regeneration causes an increased exhaust temperature, approx. 400 ºC at the outlet. Therefore, remember to use an air extraction unit that can handle these temperatures.
Regeneration can be cancelled with two quick presses on the start/stop button or by turning off the ignition.
Test conditions:
Engine idling.
A fireproof surface (no oil, dry leaves, etc.)
All power consumers disconnected.
Correct oil level in engine.
Procedure:
Start the function.
The function will go through three phases:
-Heating phase: The engine rpm is held at intermediate speed for several minutes until the coolant temperature is sufficiently high.
-Cleaning phase: The engine goes to to delayed injection. The exhausts' temperature increases and burns off the soot in the particle filter.
-Cooling phase: The engine returns to normal injection mode and the exhausts cool the particle filter.
The function is done.
If the function fails, check the test conditions and repair any faults.
