Self-Diagnostics

The Electronic Brake Control Module/Electronic Brake Traction Control Module (EBCM/EBTCM) performs system self-diagnostics. The EBCM/EBTCM can detect and often isolate system malfunctions. When a malfunction is detected, the EBCM/EBTCM sets a Diagnostic Trouble Code (DTC). The DTC represents the malfunction, turns on the ABS or Traction Control Indicators, and may disable the ABS or Traction Control System (TCS) functions as necessary for the duration of the ignition cycle.
