Few OBD-II Codes Need to be located


Recommended Posts

I ran a couple of OBD-11 runs after I gave it a routine tune-up, I disconnected the battery for about 2-3 days after the tune up, other codes that where previously "history" disappeared but i received new ones:

ACM/B1348 (history) - Very Low A/C/ Refrigerant Pressure

IPC/B1552 (history) - Keep Alive Memory (KAM) Error

IRC/B1903 (history) - Air Bag Crash Sensor #1 (Ground Circuit Short to Battery)

PCM/P1645 (history) - Evaporative Emission (EVAP) Vent Solenoid Output Circuit

PCM/P0603 (history) - Control Module Long Term Memory Reset

ACM/C1255 (history) - EBCM Internal Malfunction

IRC/u1129 (history) - Loss of Communication with AMP

RFA/U1300 (hisotry) - Class 2 Short to Ground

With that said i am trying to figure out where to start to fix these problems, car feels good and runs good but dont like having these type of problems on my mind. If anybody has ever fixed any of these problems, it would be greatly appreciated!
