PCM module reset?

Post by Wod » Sat Jul 25, 2015 2:46 pm

Hello all, just a very quick one. Does the PCM module reset option erase the whole data or just the ecu parameters?
If I perform this will it wipe the key coding and injector codes?
Thanks

PCM reset does reset of all data learned by PCM during so called self-learning process. It doesn't clear injector codes and PATS data.

There are 2 functions, Module reset and Reset all adaptations. "Reset all adaptations" does a clean up of all learned data as described above (may not exist on some models). Module reset is like a PC reset button - re-initializes the module without clean up of the KAM memory.

After re-reading this thread we have come to the conclusion you asked about Module reset and Not reset all adaptations. Sorry if we confused you :(

Hello,
Impressed of the product. What I am trying to accomplish is to reset the PCM fuel injection adaptations. However for my car the function "Reset all adaptations" is not available. As I understand from this thread I can use PCM "Reset module" instead, this will reset the adaptations. Is that correct?

After "Reset all adaptations" is there any chance to modify number of DPF regenerations? Obviously its zeroed itself :(

Hi team,

Finally I decided to give a try to the "Reset PCM module". It reported a success. It did not make any harm, but unfortunately it did not succeed in resetting the fuel adaptation either. Same big numbers of LTFT are reported right after the reset :( The car is Mondeo 2008 Duratec 2.0 145 hp . Any advice? Thank you!
