Re: Christmas Lights add up.

OOOH. Not nice.

Is $1600 for a rebuilt unit or a new one? Maybe I shouldn't ask with the chip shortages piling up lately.

New ... but that is at the GMC Dealer - I may get a price at an independtent garage.

GMC told me the truck has good breaks and will work fine without ABS.

You can get damaged GM EBCMs repaired. I don't see why i you shouldn't be able to find a reliable outfit to reman the pumps if that half is fouled up.

I know you can get the ABS pumps rebuilt for cars like the V12 E31 BMWs. The T800 trucks are a lot more common.

Re: Christmas Lights add up.

If it's loaded with mechanical relays then the re-builder really needs to find relays that are rated for the same or better cycle count and better current carrying capabilities.

Just spitballing... I wonder if they just replaced the failed relays and left the old but serviceable relays in place.

Re: Christmas Lights add up.

Yeaa typically all the fails is the control board on top of the ABS pump, Dorman makes a replacement, just hope that the torx screws that hold it on will come out. Also the air bag lights are usually an impact sensor on the core support, also a cheap easy fix, dorman also makes that.
