Stop in for a cup of coffee

Wifes 09 Journey getting lights for ABS, ESP, Traction… Clears on restart. Garage said ABS module bad - very expensive and they won’t be able to do the job. (They are mainly a tires and brakes shop.) Referred us to another place that can supposedly test better to be certain and would do the job if needed, but cant get in to even check for at least a week. So, I see there are two sections- hydraulic and electronics. Anyone know if just the electronic part will likely fix this?
