Hello and welcome to fixya.com
turned on by the systems computer it is to alert you to the fact that the computer module has detected a fault in the systems operation, this can be the engine, the emissions system or the transmission. What must be done now is to have the system scanned for fault codes, these are called OBD2 fault codes, then diagnostics are performed to determine the cause of the fault codes and repair made based on the diagnostics performed.
