Is it normal to get 24V on pin 7 of the X724 connector on a Liebherr driver display unit?

[Lily Anderson]

I'm troubleshooting a strange issue with the driver display unit on my Liebherr machine and I'm trying to avoid replacing the display before knowing for sure it's bad. Right now the problem seems to happen whenever I connect X724 pin 7. As soon as it's connected, the display starts acting up, and I'm measuring around 24V there. Would appreciate any advice from someone familiar with Liebherr electrical systems.
