Negative velocity curve from vehicle body block

I am trying to simulate a vehicle model using vehicle body block. I created the vehicle subsystem using some MathWorks references by connecting motor rotational output to tires(magic formula) and tires to vehicle body to get the velocity output. But when I try to simulate model my velocity is going in -Y axis. I tried changing the solver parameters but didn’t work. All of sudden, when I deleted the entire vehicle body sub system and recreated it l, I am getting the required output. What is the issue here ? Thanks in Advance!

Hi Vinay,

It is difficult to say what happened, but it looks like recreating the subsystem worked. It may be possible that something was inadvertently wired backwards.
