Circuit Description

WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

When ignition is turned on, BCM and PCM send identification information to SDM. BCM sends information containing the last 4 digits of the SDM part number. PCM sends information containing a partial VIN. SDM compares this information to numbers stored in memory.
