i have never seen this before but, my friends car check light is on and when i went to jump it to see what code it was throwing it didnt blink! it just stays solid......what could be wrong?

 

can't say for sure but I was told before that the ECU was bad, hope someone else can step in and help out so here's a bump

 

thanks man

 

On mine, the CEL stays on solid (when jumpered) if there's no stored code. Code zero (bad ECU) is indicated by the CEL staying off.

 

the CEL stays solid jumped and not jumped

 

bump

JimBlake just said if the cel stays solid when jumped there are not stored codes

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by game over &raquo;</TD></TR><TR><TD CLASS="quote">the CEL stays solid jumped and not jumped</TD></TR></TABLE>The CEL always has power with the ignition on. When the ECU wants to turn on the CEL, it switches on the ground side of that lamp circuit.

If we knew what model or year(?) maybe someone would know what terminal # on your ECU, what color wire. Then you could check that wire for a short to ground somewhere between the cluster & the ECU. Got a multi-meter? Know how to use it?
