Hi leatherface96

I have same problem with you, I was repair and fix now. TEst will appear cause system fail communication between akses 1,2,3
system must be communication before ( self test ) and make sure all fuction done and unit ready for use
Fail communication due to about line on mainboard broken , electronic component ( demage or fatique ) and program on IC lost
to make sure repalece broken akses3 and put on other unit, copy setup first.

perhaps my opinion can help you

I wound up figuring the problem out before I received any replies.

Simply put: Your Access 3 is bad and needs to be replaced. After I replaced mine and used the copied setups for the Access 3 module the truck was working perfectly.

hello, i also have a Crown RR5220-45 serial # 1A25794 that is showing "TEST" after it goes thru the self test. no travel, no lift. did you get a reply to this issue?

thanks,
Jay

What is the model year of your access 3?
