Q: Why the theft signal keeps on

asked by on

The theft signal always on

My car has 100 miles.
My car has an automatic transmission.

Hi there. More often than not, this problem is caused by a stored error code inside the ECU that keeps the security light illuminated. If you recently replaced a battery or other primary electrical component, this may have triggered the error code in the first place. It is probably a good idea to have a professional mechanic come to your location and first complete a check engine light inspection, so they can download any stored error codes, clear them and see if this resolves your issue.
