Circuit Description
The instrument cluster turns the ABS indicator ON during the instrument cluster bulb check for approximately 3 seconds when the ignition switch is turned to the RUN position. If the EBCM/EBTCM sets a diagnostic trouble code (DTC), the EBCM/EBTCM sends the instrument cluster the command to turn the ABS indicator ON.
