< SYSTEM DESCRIPTION >
[VDC/TCS/ABS]
DIAGNOSIS SYSTEM [ABS ACTUATOR AND ELECTRIC UNIT (CONTROL
UNIT)]
*: On for 1 to 2 seconds after the select, and then Off.
NOTE:
A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is a
operation for checking.
ABS MOTOR
• Select “On” and “Off” of “ACTIVE TEST” in “ABS” with CONSULT. Make sure motor relay and actuator relay
operates as shown in table below.
NOTE:
A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is a
operation for checking.

Description
INFOID:0000000009718236
When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current
signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).
