A system for conducting wireless communications between a vehicle computer and a remote system includes a passive radio frequency tag attached to a vehicle and electrically connected to at least one vehicle computer via an information bus, and a tag interface unit electrically connected to a remote computer system. The remote system is operable to control communications with one or more of the vehicle computers via a radio frequency link established between the tag and tag interface unit. The tag preferably includes a microprocessor-based computer electrically connected to the information bus, wherein the tag computer operates as a gateway for communications between the remote computer and any of the onboard vehicle computers including a vehicle/engine control computer, an interface module computer and a transmission control computer. The system preferably includes means for notifying the vehicle operator of various statuses of the communications being conducted, wherein the remote system is operable to control such notifying means.

A fuel and ignition control for a pulse combustion furnace includes both analog and digital timing means for fail safe operation, fuel valve control means which depend on proper cyclic operation for proper function, and flame detection means which are fail safe due to the necessity of its components providing a critical phase shift angle. The fuel control valve means includes energy storage means which is stepwise depleted to positively limit the time of valve energization in the absence of detection of flame, and is also disabled after a predetermined time by the digital timing means.

An integrated electronic control arrangement is disclosed in the illustrative environment of burner such as in a gas-fired furnace. The control incorporates a self-test feature which shuts down the furnace in the event of any one of a number of possible sensed faults. Self-testing occurs automatically before an attempt at ignition and during furnace operation. Proper functioning of the sensor which senses for induced air flow through the burner combustion chamber is tested prior to enabling a fan which causes that induced air flow. Air flow is confirmed by sending to and receiving back from the sensor a sequence of pulses. Should air flow not be sensed during a combustion period, combustion is terminated. A flame sensor is provided for determining the presence of a flame in the combustion chamber. During times when a flame should be present, pulse sequences are sent to and received back from the flame sensor to confirm that a flame is present.
