Crown SP3020-30:
Stuck in Manual mode

We have a crown SP3020-30 that was having problems with the display module. You would turn the key and just 2 little green lights would come on the board no POST beep. We replaced the display module with 1 we found on the internet. It now turns on beeps a single time for POST, but it says manual and has the service wrench lit up. We still have the ability to raise and lower the unit but we can't drive or turn the unit. If you start it up with your foot on the deadman switch you will hear the break disengage but immediately reengage. If you start it without the switch engaged it will not even try to disengage. I can't seem to figure out how to find any error codes as all it does is show me the manual message. If I click the information button I get info that says c1 - 423 and it counts up to c15 - 423. From looking at an incomplete service manual that says its a problem with the guidance system. We don't have a wire guidance system on this orderpicker and never did.

Now we replaced the display module with a new 1 but the only difference was after the serial number on the original is say Rev G which the new 1 doesn't and I couldn't find 1 that did. Any thoughts?

423 is a guidance module not connected code. You mentioned you do not have guidance... Sounds like the settings in the truck thinks it does and cannot communicate with it. Like mentioned in previous response. You need a service terminal to check and correct your settings. Without the service terminal you are shooting in the dark and cannot change/correct any settings. When you buy modules (specially used) you never know what options are turned off or on. They always have to be set up to your specific options on your truck. If you have removed options, the controllers have to have the option turned off with the terminal or the display will throw fault codes and in most cases lock the truck down.

It's all just nuts n' bolts.
First thing you will need is handset to plug in under the accelerator grip to turn off wire guide and any thing else that the truck this came off of had your does not.
