If you have an * ahead of the 011 you have more then one fault in the traction drive system. What you need to do know is put the truck's Control System into self diagnostics to help you define the issue or issues. To do this you will need to push the FN 1 and FN 4 buttons on the lower left of the dash in at the same time you are turning the key ON. The display screen will show window 500 ( SELF-CHECK FUNC ). Once this screen shows in the screen view that is above the FN buttons, you will want to push in the FN 3 button. This will activate all of the power contactors momentarily and then window 610 will appear in the screen's view. You will now push in the FN 1 button to reach window 611 that will define which component circuits are the cause to the loss of traction drive. You will need assistance to interrupt the error numbers that appear here.

send me model serial will check the manual
