The Fault Code Details report includes data about the status of indicator lights. (See The Fault Code Reports for more information.) This is what each lamp status means:
- Red stop lamp status: Indicates a problem that is severe enough to warrant stopping the vehicle.
- Amber warning lamp status: Indicates that there is a problem with the vehicle system, but it is not serious enough to stop the vehicle immediately.
- Malfunction indicator lamp status: Indicates that there is an active emission-related trouble code.
- Protect lamp status: Indicates a problem with a vehicle system that is most likely not electronic subsystem related (for example, the coolant temperature has exceeded its defined range).
