Using the DRBIII (R): Overview

The TCM and other components have the ability to interface over the communication bus. The DRBS Scan Tool connects to a Data Link Connector located in the passenger compartment. This allows communication with the TCM.

Refer to the DRB user's guide for instructions and assistance with reading trouble codes, erasing trouble codes, and other DRB@ functions.
