Hello toyzila. I am having the same recurrent problem also. Changed the controller and the truck worked for 2 weeks only. Now same code 61 and LED #4 on the controller is on again. Onlye LED #4 is on. What else besides you have suggested should be done? How can I check if Controller is bad and if so, any suggestions on what may be cuasing the Controllers to go bad?
Sorry for all the questions, but this is a tough one for us.
Regards,
OB1
