I changed my stereo (radio) and after that SRS light came on,I run the scanner and it says that port in the front and rear ignition circuit short circuit to ground are malfunctioning, codeB-1010,1012,1025,1027,, i tried to reset codes and doesn't allows me to,any help!!?? I check the fuses and they appear to be fine,I'm wondering if there is a main module or main command box or something that is telling the system about the loose or short ground, I will appreciate anyone's help with this issue.
