ABSTRACT:
A method and apparatus for monitoring a plurality of vehicle conditions and providing an indication of unsatisfactory conditions. A warning indicator is provided for each condition and a main warning indicator is also provided for giving warning when any of the sensed condition is not correct. An arrangement is provided wherein all of the warning indicators are illuminated when the main switch of the vehicle is closed so that the operator may ascertain that all warning systems are operational. The individual warning indicators are then operated in sequence and are extinguished if the sensed condition is correct. If any sensed condition is not correct, the main indicator will be illuminated and that particular condition indicator will remain illuminated while the remaining checks are completed. This sequential testing is done only after the vehicle is started or if initiated by the operator. The operator is also provided with an override which permits change in the mode of the main warning indicator once it has been initially operated.
