How to kmow if the FLASH is correct?

[skinerd]

Did it work ok before the mod??

Do you have the PCR20 message??

Do you have 13-18 volts alternating at sat in.

There are numerous reasons for this error and all have been addressed here many times. DO SOME REASEARCH, READ, SEARCH AND READ.

Come on people, before posting a question, at least read a little and see if that same question has not been asked before.
Have any idea how frustrating it is to answer the same thing over, and over???? When the answers are already posted???
