I see the "Reset pilot injection quantity learned values" was implemented here for the Ranger 2.2. Is there meant to be a process followed?FORScan wrote: ↑Thu Nov 20, 2014 1:54 pmThis function was added as a result of investigations on this Focus Mk3 1.6 TDCi problem:+ Service function "Reset pilot injection quantity learned values" for:

Modern diesel engines with Common Rail have so called Pilot Injection function that means injecting small volume of fuel right before the main injection event. This reduces combustion noise and improves the work. The fuel quantity of the pilot injection depends on many conditions (mode of work, wear etc), so it is a subject of self learning process. In some cases these learned data have to be reset and re-initialized (for example, if one or several injectors are replaced). Some powertrain control modules are able to calculate initial values for pilot injection quantity based on injectors' C2I codes (this is why it is so important to program new injectors in PCM). But some PCMs also require additional procedures to learn new values. For some reason, the "Reset All Adaptations" sevice function on Focus Mk3 seems to be performing incorrect initalization of these values, so this function was added to solve the problem, first of all.
I just get a wait 5sec...then a prompt to turn IGN off, then 100% indicated...
Is the engine meant to be running at the time?
Some help would be great.
