Class 2 Serial Data Link

The class 2 serial data link allows a scan tool to communicate with the listed modules for diagnostic and testing purposes. The class 2 serial data link is located at the data link connector (DLC) terminal 2.

• Driver information center (DIC)
• Electronic brake control module (EBCM)
• Instrument panel cluster (IPC)
• Inflatable restraint sensing and diagnostic module (SDM)
• Memory seat module (MSM)
• Powertrain control module (PCM)
• Radio
• Theft deterrent control module
• Vehicle interface unit (VIU), if equipped

The class 2 serial data link may also be connected to the video disc player and rear video/audio/HVAC module if equipped. However the video disc player and rear video/audio/HVAC module will not communicate with the scan tool, do not set DTCs, and other modules do not set DTCs against them.
