Monitoring system for electrical connections in a transmission

摘要

A control for sensing impending and existing electrical connection faults in a vehicular transmission control circuit (42) including a plurality of individually energized and de-energized electrical devices such as electric motors (36 and 38) and solenoid-controlled valves (24 and 30). A voltage monitor (46) senses voltage drop across a power source (44) for properly operating devices and compares it to an expected voltage drop (REF) to determine if an electrical connection fault condition exists. <IMAGE>
