Thanks for the update. If there is an error light there will be fault codes logged in the ECM or TCM memory. Have the codes retrieved so we know what faults are logged. Now this fire alarm is a smoke detector in the living quarters of the Bus? Or are you calling a warning buzzer a fire alarm that is going off due to its audible signal and it is indicating an engine or transmission fault?

I have both the Audible alarm and the dash error light as soon as the system has power up. There are not any smoke detectors this is still a passenger vehicle.

Thanks for clarifying. The term fire alarm threw me off a little. So this is an audible warning for a fault in the engine or transmission. There will be likely codes logged in the ECM memory. A scan tool can pull these codes which will help isolate the problem area and circuit.
