Last week while driving home my car didn't sound right. I stepped on it and didn't have any power. I checked my Scanmaster and noticed a MAL code of 51. I was able to make it home and disconnect the ECM. I then connected the ECM and the code went away. I haven't had a problem since. I now notice when I turn the key to start my car, the Scanmaster shows a 2 and then goes away. No MAL codes. Is this normal and something that I never noticed before?
