Self-Diagnostics - Delco VI

The EBTCM contains sophisticated on-board diagnostics that can detect and often isolate system malfunctions. When a malfunction is detected, the EBTCM sets a Diagnostic Trouble Code (DTC). There are 60 diagnostic trouble codes that assist with diagnostics. The DTC represents the malfunction, turns on the ABS and/or ETS/TRAC off indicators (in almost all instances if equipped), and may disable the ABS/ETS functions. The EBTCM can also diagnose whether the malfunction is intermittent.
The following actions occur when using the Scan Tool with the ABS/ETS:
- The Scan Tool specifically identifies the last DTC.
- The specific ABS or ETS data stores at the time of the malfunction.
- Information about the first three DTCs set and the last DTC set becomes available.
- The input and output can be monitored.
- Malfunction confirmation and repair verification are enabled.
- The manual control of components and the automated functional tests become available.
