Hi guys,

This is what happened suddenly. Any idea what could be the problem based on those type of symptoms?

Need to search this forum, now lots of fixes, think you need to go through all of them.
Start with cheapest first, salmon relays. After that a code reader is a must.
Don't bother with the phone app. type of reader unless more expensive ones, get a dedicated reader with cable attached.
I tried several bluetooth obd readers, they were useless would never connect.
