PINPOINT TEST H: U1000:00

Normal Operation and Fault Conditions

The BCMC uses solid state drivers to control the output of several systems. When an overload occurs on any of these drivers, the BCMC disables the output and tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to 3 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 - System Operation and Component Description (419-10 Multifunction Electronic Modules, Description and Operation).
