2000 Silverado what/where is ABS relay? Sign In

2000 Chevy Silverado with 4.3 L engine has 129,5000 is showing multiple code "history", starting with CO 0265 using a Snap-On code reader.

The ABS light is on intermittently and the brake warning light is on constantly.

That code says it's the ABS relay. There is no such relay in the fuse/relay box under the hood. The ABS unit is under the frame next to the in-line gas filter, but I can't find a relay other than the ones in the fuse/relay box under the hood.

Can anybody help?

Not good news. The relay is incorporated into the control module and that's what you will have to replace.

You are absolutely right. Not good news, but better than no news and still puzzled.

Gonna replace the control unit. I've never seen one on the frame by the fuel filter.

Do your homework first and make sure it's receiving all the power and grounds that it should.

Yes, checking for power, ground and no open or shorted wires is absolutely the place to start.

Short funds are holding-up the process now. So thanks for all the help.

As I stated in the first reply, the relay is incorporated into the module and the whole module has to be changed.

Why not try a $15 buck relay and see what happens? Not everything is some $1,000 problem!

Because there is no relay to change.
