Hi all !

I have one mazda 3 edc16C34 with P1187 ( on first turn ignition car is in limp mode .On second no problems) fault code. I remove dtc on flash
, write again , no faults but car in fist time no power , limp mode. If i turn off and on again i have power and everythink is ok. This is the common problem on ford , mazda edc16c34 1.6 tdci .

The only solution as i know from forums is to flash with vcm ids new calibration software but i Dosen't have VCM IDS.
I flashed again the original file and fault code P1187 appear again on first time opening ignition , on second no faults.

Can anyone help me ?

it is true but eliminate dtc is a way to study the problem and to understand ..
Many times the solution as in this case dtc off does not solve the problem, but this is becoming a way of working wrong ...

you can do dtc off only in some cases ..
