The class 2 serial data link allows the following modules to communicate and share data with each other:

• Body control module (BCM)
• Digital radio receiver (DRR)
• Driver information center (DIC)
• Digital video disk (DVD)
• Electronic brake control module (EBCM)
• Instrument panel cluster (IPC)
• Head up display (HUD)
• HVAC module
• Left hand power sliding door module (LHPSDM)
• Memory seat module (MSM)
• Powertrain control module (PCM)
• Radio
• Right hand power sliding door module (RHPSDM)
• Inflatable restraint sensing and diagnostic module (SDM)
• Vehicle control interface module (VCIM)

The class 2 serial data link allows a scan tool to communicate with the above modules for diagnostic and testing purposes.
