Any thoughts?

A dead battery causes all kinds of issues, that are typically cured by a new one.

You need to check your battery connections for corrosion tightness and also check the other end of the battery negative cable where it is attached to ground to make sure it is in good condition.

How does one clear the codes?
Will check negative etc.
Dom
I miss-understood "clearing the codes",and have now done so.
Went for a drive-this is what i have:
10 PCM - P 1571 HC
TCS - No Comm
58SDM - U1040 HC
Any more thoughts?

Thanks for the help again Bill-checked these grounds visually and with the test light-all good-not seeing any bad fuses either!
Dom







Make sure that you read the fuses powered by RUN in ON & Start with the ignition ON and make sure that those fuses read full battery voltage!

I did think it was the Traction control switch, but I was still checking things to make sure.
What I found was the ground next to the battery under the battery heat shield shown above by Bill Curlee in the second pic was super loose.
Thank you Mr Curlee you saved me quite a few hours of going crazy looking and testing.
