I'm working on a 2018 Yukon whose front bumper was slightly dinged, not on but near one of the sonar units for the parking assist. It now has the "Service Parking Assist" message every time it starts up. The rear-view camera works, but the sonar does not - front or rear. A visual inspection shows no damage to the sensor or wiring. I can't tell if the sensor is damaged, the wiring is damaged, or the system just needs a reset from its minor trauma. My best scanner is a Launch CRP123, which does not have a selection for the parking assist module on this vehicle. Can anyone recommend a reasonably priced scanner that will read and clear codes from the parking assist module? Thanks!
