Abs (Anti-Lock Brake System): General Description: Notes

The ABS consists of components such as the wheel speed sensors, stoplight switch, hydraulic unit assembly (integrated with ABS-ECU), ABS rotor, and the ABS warning light. If a problem occurs in the system, the malfunctioning components can be identified and the trouble symptoms will be memorized by the diagnostic function.

In addition, reading of diagnostic trouble codes and data list and actuator testing are possible by using the Scan Tool.

If the ABS hydraulic unit is faulty, the ABS-ECU must be replaced.

The ABS-ECU runs a self-check for 3 seconds upon start-up (also ignition switch ON, engine stopped). The ABS warning light, TCL warning light, and TCL indicator light should be illuminated during the self-check and turn off when the self-check completes.
