Chart 3
Diagnostic Chart Part 3:
Schematic:
On the V6 (L81) application, the Scan tool communicates over a KW 2000 data link.
The BCM did not indicate any DTCs relating to the ECM or TCM up to this point in the "Vehicle On-Board Diagnostic System Check." Since the Scan tool cannot communicate with the ECM or TCM, this chart will diagnose faults associated with the KW 2000 data link.
