ABS Light: Description and Operation

Vehicles equipped with the Anti-lock Brake System have an amber "ABS" warning light in the instrument panel. The "ABS" warning light will illuminate if a malfunction in the Anti-lock Brake System is detected by the Electronic Hydraulic Control Unit (EHCU). In case of an electronic malfunction, the EHCU will turn "ON" the "ABS" warning light and disable the Anti-lock braking function.
The "ABS" light will turn "ON" for approximately three seconds after the ignition switch is to the "ON" position. If the "ABS" light stays "ON" after the ignition switch is the "ON" position, or comes "ON" and stays "ON" while driving, the Anti-lock Brake System should be inspected for a malfunction according to the diagnosis procedure.
