Diagnostic Aids
If the only DTC that flashes is a "History" code (DTC 31), the problem may be intermittent. Try performing the test shown while "wiggling" wiring and
connectors; this can often cause the fault to appear. Check for poor connections at the BCM connector, which could cause an open or an intermittent
fault. Refer to "Intermittent/History" DTCs near the beginning of this Section.
