1.
This test checks circuit 156 for a short to B+ with the BCM disconnected.
2.
Knowing that the short to B+ is in circuit 156, this test isolates the short to one side of connector C200.
4.
Knowing that the short is in the C2OOC side of circuit 156, this test isolates the short to either the harness or the Rearview Mirror.

This test checks for a short between circuit 156 and circuit 149.
Diagnostic Aids
If the only DTC that flashes is a "History" code (DTC 32), 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.
