resolve the problem.

the AC traction controller and the 1222 are operating correctly. Resolve any
problems with the traction software or CAN communications before continu

ing on to the commissioning procedures.
Steer Direction
Parameter and monitor values for wheel position and steer motor speed are
signed (i.e., they are positive and negative values).
Right wheel positions (positive values) are such that when traveling in
the forward vehicle direction in a vehicle with the steered wheel in the front
the steer direction is to the driver’s right.
Left wheel positions (negative values) are such that when traveling in
the forward vehicle direction in a vehicle with the steered wheel in the front
the steer direction is to the driver’s left.
In vehicles where the steered wheel is in the back, these directions are
reversed.
