short answer to question, no as you have lsds fitted
but you can try raising the magna so all wheels are off the ground. spin each wheel one at a time till the the light comes on....they usually need three or four revolutions. The problem you might face is with the drag in the lsd....it will want to turn both wheels together.... so you may not be able to say which wheel is cause a fault. It will most likely be a dirt clogged sensor hole causing the issue
