Abs (Anti-Lock Brake System): General Description: Notes
The ABS consists of components such as the ABS sensors, stoplight switch, hydraulic unit in hydraulic brake booster (HBB), HBB buzzer, M-ASTC-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.
The M-ASTC-ECU runs a self-check for three seconds upon start-up (also ignition switch ON, engine stopped). The ABS warning light should be illuminated during the self-check and turn off when the self-check completes.
