Hi Im David, anti theft light stays on when cranking?

Expert:  rpmdiag replied 1 year ago.

Hi, and welcome to Just Answer. I'm Ron and I'll be helping you today.

This issue sounds like an instrument cluster starting to fail.

There is one test to do to find out for sure, but it does involve a scan tool to test the cluster in bidirectional mode. It will also tell us if there are any stored codes for this issue too.

Thanks, Ron

Sorry David, I'll opt out. We crossed wires here.


Expert:  rpmdiag replied 1 year ago.

It looks like David opted out too.

I only did because he and I were both answering the same question at the same time.

I apologize to you for any inconvenience, so please try what I originally recommended and let me know if you need any more help.

Otherwise, please rate me 5 stars for my answer and keep this link in case you need me again later on.
