Sorry, database is down. I'll opt out so other experts can help you. Please don't rate or reply until another expert responds or the site will cycle this back to me.

Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.

Does your vehicle have 2 or 4 wheel ABS?

When using a scan tool does the GEM show an accurate speed signal?

So far a faulty GEM or damaged wiring looks to be to blame.
