Hand Controller not Working Right
 

My hand controller will switch screens adn turn on and off on me all the time. i always keep it on the data screen and somehow without me touching it it will turn off then come back on on different screens. everytime its different. im worried its is going to change my stuff. Has anyoen else has this happen before? What can i do?


Also during cold weather it will turn on and off mor often.

On the way home from work tonight it wouldnt even work. the screen was very dim and black. Anyone know whats going on?

sometimes mine will start to switch to diffrent screens by it self
or even lock up

I just disconnect the serial cable from it and re-insert it
that always does the trick

check the pins on both ends
and make sure there in good on the ECU and handset

does it happen to all hand controller?
