First, check the battery voltage and connections. Low battery voltage can cause issues with the electronic control system. Make sure all connections are secure and clean.

If the battery and connections are fine, then it could be a faulty control module. You can try resetting the control module by disconnecting the battery and touching the positive and negative cables together for a few minutes.

L

Another possibility is a software glitch. Try updating the software of the control system and see if that resolves the issue.
