The Electronic Brake Traction Control Module (EBTCM) contains sophisticated on-board diagnostics that, when accessed with a scan tool, are designed to identify the source of any system malfunction as specifically as possible, including whether or not the malfunction is intermittent.

When using the scan tool, the last Diagnostic Trouble Code (DTC) is specifically identified, and specific data is stored at the time of this malfunction. Using the scan tool, each input and output can be monitored, thus enabling malfunction confirmation and repair verification. Manual control of components and automated functional tests are also available when using the scan tool. Refer to Scan Tool Diagnostics for more information.
