I have a 2001 LS and when driving I am getting different warning lights flashing on my cluster but the performance of the car doesn't seem to be hurtin'. I'm gettin the battery light, security light, and service car light. Anyone have any idea what could be going on??

Have the charging system checked.

The usually when the CEL light flashes its because it detected a missfire

Get the car scanned. My dad's 02 was doing something like that and it was the BCM.
