Anti-Lock Brake System: Description
Anti-Lock Brake System (ABS) allows the driver to maintain steering control during heavy braking by fluctuating brake line pressure. System consists of an Electronic Control Unit (ECU) with LED (for diagnostic usage), wheel speed sensors, actuator (electro-hydraulic unit) and an ANTI-LOCK warning light located in dash. See Fig 1 .
ANTI-LOCK warning light notifies driver in event of an ABS system problem. LED located on ECU will flash (indicating trouble codes) when warning light is illuminated.
