Service Electronic Brake system- Anti-Lock brake and Park sensors- all inop same day

[KC15842]

As of yesterday the ABS, Anti-Lock and park sense, including the switches are illuminated. I get a message when starting the truck, the lights are on the dash and the center consul switches are illuminated. Anyone have an idea of where to start? A harness or connection somewhere? Thanks

Check the specific ABS codes with a scanner. That is always step 1. Cheapo $20 scanners and many ones that autoparts stores have will not read the ABS module.

Have your battery load tested. If it’s going bad the truck freaks out
