Section 186 (Anti-Lock Brake System W/O Traction Control): Description
WARNING: This page is about a different car, the 2003 Toyota Camry Solara and 2002 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
Anti-Lock Brake System (ABS) consists of an actuator, control relay (solenoid relay and motor relay), ABS Electronic Control Unit (ECU), and 4 wheel speed sensors. ABS ECU and relay are part of actuator assembly. See Figure.
An ABS indicator light is located on the instrument cluster. Indicator light comes on for 3 seconds as a bulb test when ignition is turned on. A primary check is performed after each engine start, and when initial vehicle speed exceeds 6 MPH. If brake pedal is pressed before vehicle speed exceeds 6 MPH, primary check will not occur until brake pedal is released.
NOTE:
