I looked at the codes on my truck this morning and am trying to figure out what this means. I cycled the key 3 time and this is what came up, it pauses about 2 seconds between each message:<br><br>P PCU<br>P done<br>P ECU<br>P done<br><br>

You got yourself no codes there.<br><br>What it's saying is:<br><br>checking Primary Control Unit<br>done checking<br>checking Engine Control Unit<br>done checking<br><br>If there was any codes, the P would be followed by a number.<br><br>phox

Thanks for the response. I feel kinda dumb, but it never hurts to clarify! ::)
