Scan Tool Does Not Communicate With EBTCM

Diagnostic Chart:

Schematic:

The electronic brake traction control module (EBTCM) has a dedicated KW2000 data link. This data link is only used for diagnostics/reprogramming. If the Scan tool cannot establish communications with the EBTCM the fault could be caused by:
^ KW2000 link from the DLC to the EBTCM is open, shorted to ground, or shorted to voltage.
^ A fault in the EBTCM
^ Power/ground circuit fault to the EBTCM.
