GENERAL DESCRIPTION

ANTI-LOCK BRAKING SYSTEM (ABS)

35B-2

.

GENERAL DESCRIPTION

M1352000100324

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 sec-
onds upon start-up (also ignition switch ON, engine
stopped). The ABS warning light should be illumi-
nated during the self-check and turn off when the
self-check completes.
