Hi, I have the JP Diag software and cables (Lonelec set of cables) for my 05 749. All works fine apart from it wont let me reset the service indicator. I can see everything fine, but the reset button is not highlighted? Nor is the TPS reset, but i don't intend on using this. Have i not done something to enable this/ these functions?
You need to get a (free) licence from JP to enable them. Paste the ECU info displayed in the JPDiag window here
