GR-20J - No drive

Hello I have an older model 2013 Genie GR-20J that wont drive, the switch for drive mode doesn't light up, we have checked the switches and wiring and believe all to be ok.

Appreciate any ideas, also does this model have a diagnostic port anywhere or is it too old?

Showing items 1 - 3 of 3 results.
code 1A86 is brake coil open - check the connections at the brake coil, if no problem found then replace controller.

code 08A75 is BUSCAN incorrect - The platform controls circuit board is not receiving the CAN signal from the controller.
There may be an interruption of the BUSCAN signal. Check the connection of the BUSCAN between the modules. Otherwise, there is an internal fault in a module which causes a transmission error, or there is excessive noise on the BUSCAN line.

code 16A06 is No communication
The diagnostic display is not working properly.
Check wire connections. Repair or replace the diagnostic display.

code 1A45 there is no reference to this code in the fault code chart in the service material provided by genie.

Let me ask, are you sure you have the connections connected correctly?
It is odd that so many codes would be coming up unless there are damaged connections or the plugs connected incorrectly. Check any wiring or cables for chaffing or damage.

Hi Thank you for replying sorry for the delay, the s/n is GR12-363 and when I put it back together and turned it on I have the following codes:
1A86, 08A75, 16A06, 1A45,
01A61 I believe came up when I tried a lever.

It wont switch to drive in the basket, no LED comes on.

having a serial number would be helpful.
but does it not have a display gauge on it? with an LED window?
if there are any issues it would be displaying a code either when you power the unit on or when you try to drive it.
