NO I don't have a scanner
Not 100% but a lot of folks claim the OBD2 scanner can clear it. Have you found the OBD2 port and plugged in the scanner?
On my 6520, there is a little holder that looks like an inline blade fuse. I remove the cover, turn the key on and wait 10 seconds, then jump across the terminals with the key on. That resets it. Sometimes it takes more than one try to get it reset. It is right beside the fuse block.
