The BCM uses solid state drivers (Field Effect Transistors (FET)) to control the output of several vehicle systems. When an overload occurs on any of these drivers, the BCM disables the output and tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to three progressive thresholds established for each circuit. At each threshold, DTC U1000:00 sets along with the DTC associated with the affected circuit. For additional information, REFER to: Module Controlled Functions - Overview (419-10 Multifunction Electronic Modules, Description and Operation).
