Notes on Intermittents

If an intermittent Code B128 is being set, manipulate circuits 308 and 44. When checking circuit 308 for an open, observe BCM input BI02 and watch for the change-of-state indicator to change from an "0" to an "X". When checking circuit 44 for an open, observe BCM data value BD52 and if the failure is induced, the reading will jump from its normal reading to zero.
