What exactly does error code 55 mean? (completion of fault code display on the CEL)
I just had my PCM replaced and a day later the jeep is acting up again, like it did before. but this time it actually displayed two codes.
code 12- which means battery disconnect- direct battery input to the pcm was disconnected within the last 50 key on cycles.
code 55- N/A- completion of fault code display on the CEL
does 12 basically mean that the battery cable was disconnected from PCM, like when they disconnected the old and installed the new?
and I have no idea what 55 means? there are more issues with vehicle than able to display? i dont know.
but anyways I decided to check the codes because it takes a couple key on's to turn the jeep over. then when it does it doesn't start up strong.
