Default 2001 Z06 throwing codes

Hey everyone my son and I just added a 2001 Z06 to our Corvette family. I know its probably on here somewhere but its throwing some codes. Either someone that knows what they are or a link to where we can find them.

10-PCM PO 803HC
BO-RFA U1064 H
58-SDM U1040 HC
10-PCM P1698 HC
40-BCM BO432HC
10-PCM P1571 HC

Thanx Everyone!

Thanx

The link above should tell you what you need to know. Just so you know going forward. If the code ends in "C" it is current. If it ends in "H" it is history, and no longer happening. "HC" is history and current. That means that you don't have to worry about the BO-RFA U1064H code as it is no longer a problem. You want to figure the others out.

DTC U1001-U1254 lost communication with xxx.
Electronic brake control module, EBCM, is module ID 040 so I'm guessing it is lost communication with EBCM

First thing I would check would be the battery connections and the battery voltage. A low battery voltage or any sort of voltage dip will throw all kinds of codes

As it's new to you, I suggest replacing the battery with an large AGM type and remove/inspect under the tray for acid spillage. There is a computer and 2 main wire bundles underneath and could be damaged by a leaking normal acid battery. AGM style batteries are not much more money and eliminates one of the few sources of issues on these great cars!

Enjoy your car!
