I have a Toyota 7FBWS13 - 41229 that is displaying a code 28 and a code 150. The unit is 24 volt and has a Curtis controller, I have hooked up a handset and I am seeing 22.5 volts at the controller with the handset, I know I should be seeing a higher voltage there which could be why I am seeing the code 28, but I am not seeing any tiller card imputs to the controller. The Controller and the etacc tiller card are new. The tiller card has been hooked up to a computer and setup for this unit. I have checked the can wiring and I do not see an issue there, but I maybe missing something.

Any words of wisdom?

Thanks
