The EBCM contains sophisticated on-board diagnostics. When a Scan Tool accesses the EBCM on-board diagnostics, the EBCM on-board diagnostics identify the source of any system malfunction as specifically as possible. The EBCM on-board diagnostics also diagnose whether the malfunction is intermittent. There are 3 VES Diagnostic Trouble Codes (DTCs) that assist with diagnostics. Refer to the Diagnostic System Check - ABS for VES DTC diagnosis.

The following actions occur when using the Scan Tool:

    • The Scan Tool specifically identifies the last DTC.
    • The specific data stores at the time of the malfunction.
    • Information about the first five DTCs set and the last DTC set becomes available.
    • The input and output can be monitored.
    • Malfunction confirmation and repair verification are enabled.
