cold start problem

12 and 55 are start and end of codes ... 12 means the battery was recently
disconnected/CPU lost power and 55 means end of codes. Without at least one
more code in the middle, these 2 will not be any help in troubleshooting
this issue.

That basically means "no codes". 12 means "battery disconnected
recently", or is always displayed if any other codes will be
displayed. 55 means "end of codes".
