Looks like I stand corrected, and Andr'e is a wild-man. I presumed the ABS looked at the relative speed of both wheels. Maybe not. I live just east of Lake Shawnee, if you're familiar with Topeka at all. Used to live in Lawrence many years ago.
Dean , Andres,
On IABS, to finish the pull-away test, I had always assumed that the system is looking for rotation of both wheels and at some similar speed. BUT, based on Andres post, it is quite possible that any rotation up to a certain speed or distance (as published in owners's guide) is good enough to satisfy the pull-away test completion.
However, until proven otherwise, I still believe that later on, once you attain a certain minimum speed, a rotation of both wheel (within a tight percentage of each-other) is needed to avoid an ABS fault. When I have time I will test following:
(1) go for a very short ride and let the ABS finish its pull-away test (will attain at least 30 mph)
(2) will park on center stand and let engine run (so that ABS is not re-init)
(3) with belly fairing already removed, I will install a suitable device under engine sump to support rear and front wheel in the air. At that point, I will re-try Andres procedure of 1st gear and front wheel rotation.
Step 3 should generate a fault, but I suspect that the IABS system does not care about rotation until a certain minimum speed is attained by the rear wheel (speed data based on rear wheel ABS-sensor).
