Body Control System Diagnostic System Check

Connect scan tool to Data Link Connector (DLC). If scan tool powers up, go to next step. If scan tool does not power up, go to SCAN TOOL DOES NOT POWER UP .
Turn ignition on. Attempt to establish communication with Body Control Module (BCM). If scan tool communicates with BCM, go to next step. If scan tool does not communicate with BCM, go to SCAN TOOL DOES NOT COMMUNICATE WITH CLASS 2 DEVICE .
If any communication DTCs exist (DTCs beginning with a "U"), go to SCAN TOOL DOES NOT COMMUNICATE WITH CLASS 2 DEVICE . If no communication DTCs exist, perform appropriate test. See BODY CONTROL SYSTEM DIAGNOSTIC TROUBLE CODE INDEX table.
