Loses communication with ABS was created by mjpatitucci
Good day fellow Technicians,

I am troubleshooting a 2015 Honda Pilot, 101K miles, that looses ABS signal when driving vehicle above 33.84 mph according to my XTool D8BT scanner. At first I suspected the scanner until I checked other systems which are communicating fine. I did another total scan of the vehicle once it was sitting in the driveway. Sure enough… no error codes. I have a subscription to Alldata for the vehicle and will be doing a lot of reading. Has anyone else have a similar experience, loosing communication with a module at a certain speed? Thanks in advance for your input.

Mike

What, exactly, are you trouble-shooting? Are you getting ABS warning lights? 
The fact that you have no codes makes me believe that this is a tool limitation, rather than an actual communication issue.

I agree with Chad. In the past it was not uncommon for Asian imports to drop communication above a certain speed. At least with Snap On and OEM scan tools, there would be a warning on the tool that it would cease to communicate with abs while driving. Unless there's a tangible symptom you are trying to diagnose with the abs, I wouldnt read too much into it.
