Crown SHR5500:
Access123 Error 208 No lift controls reversed

I have a Crown SHR550 with the Access123 system. The Factory code 2311 gets me into the menu system if that helps. The issue I am having is it will not lift at all. I have a wrench on the screen and a code 208. What is strange is the red stop button surges the machine at the user about 5 feet and the controls seem reversed. Down is forward and up is reverse. None of the other controls on the stalk work. No horn & No fork controls at all. Is there a way to just reset the Ecu or clear the codes? Unit only has 1209 hours on it and is in great shape. Please let me know.
Thank You,

From my experience working for a Crown dealer for 13 years, electronic parts are not usually returnable. If you buy new access modules from a Crown dealer and try them you will likely NOT be able to return them. Also new access modules will may have a newer software which will not match the rest off the modules software. The best approach if you think it's an access 2/3 issue is if you have another unit with the same software version, swap the controller and see if the problem goes to the other unit.

Typically I replace both and not just one. The best way to test is to replace the modules and see if it works, if it doesn't those parts should be returnable. Typically with can issues they are very hard to test.

Would the crown dealer be able to actually test the modules or is it a replace 1 and hope kinda deal? What is the normal procedure for replacing these?

There is a possibility both of those models may be bad. I'm not sure on the official specs but they should hold voltage for longer than 80 seconds.

I checked the voltage on access 2 3 and it takes about 80 seconds to drop from 24v to 2v.

Yeah that means one of the two is bad or both are bad. I've also seen the access 7 module be bad and throw this code. There are a few tests you can do to check the capacitors in each module to be sure by measuring across the positive and negative terminals and watching the voltage drop after turning off the key.
If the module capacitors are bad the voltage will quickly drop to around 0v. Otherwise it should hold around battery voltage.
Typically the event code instructions aren't always right but it's provides good things to try.

Well it passed all of the 208 procedure tests. It ends on "Then replace ACCESS 2 and 3 combination." Is it saying that that module is bad? Crown 140440 or

CA stands for Connector Assembly. A connector Assembly is when a PC (plug connector) and jc (junction connector) are connected.
So yes CA and PC are the same thing, it just tells you what end of the connector to test

So I am trying to go through the 60ohm check and for the life of me I cannot find CA240 connector to check. I see it on the descriptions and such but there is no plug label as CA240. I see PC240. Does CA vs PC mean something I am missing?

You can contact crown for service manuals and parts. I believe they have paper and pdf options available. Depending on where you are in Michigan there should be a branch close by.
If it does end up being a bad module, you will have to have the proper software flashed to the truck, so it's not a bad idea to know where your nearest branch is incase you need help with that step or any other steps

Any idea where I can get a service manual for the diagnostic procedure. Also Thank You like a million times for the help.

Then it sounds like a CAN issue. I'd start with verifying both the positive and negative terminals on the access 2, 3, 4, 5, and 7 have a good connection to the battery and are reciving voltage. If they all are, verify the resistance between the modules on the high and low circuits. Otherwise the service manual will have a more in depth guide to troubleshooting this issue under event code 208.

Well I tried 3.1 & 3.2 both turned the wrench off for a second but the code came right back. No other codes are shown.

Event code 208 is a can comminication error. You can clear this code by going into the service menu, scroll down to events, scroll down to E3.1 and when prompted select yes. This should clear any codes currently on the lift. If this code reappears then you would need to troubleshoot the can wiring as there is a fault somewhere in the can system. Typically another event code is thrown along with 208 to provide more information. From the symptoms you are experiencing it does sound like there is an issue within the can communication circuit. If this code is thrown again or you havent cleared it yet, are there any other codes present in the log history?
