Will resetting the PCM wipe out my H&S Mini Maxx? New junction box, new problems.
It all started with the locks not working whether I used the buttons, the remote, or the key pad, so I took it to ford and they put in a new smart junction box. That fixed the locks but opened up a new can of worms. The blinkers now flash a 1000 mph but the flashers are normal, the interior dome lights flash on and off continuously if the key is on or truck is running, and when using the remote to lock/unlock the truck the lights do not turn on like they should. So now ford is saying they need to reset the PCM and my question is will that wipe out the chip if I don't return it to stock for the reset? Its not a problem to unhook the chip but its at ford and I'm at work.
It hasn't thrown any codes.
