Important: DO NOT replace the body control module (BCM) unless a Diagnostic Trouble Code (DTC) remains current after all the DTC tables have been executed. DO NOT replace the BCM based on History codes.

The BCM has the following characteristics:

•	Connected to the Class 2 serial data link

•	Capable of setting Diagnostic Trouble Codes

A history DTC code is a fault that disappears in the next ignition cycle. The History DTC codes are useful in diagnosing an intermittent problem. An explanation of these History DTCs is given in the following table:
