field of each ABS sensor. The amount of voltage generated at each wheel is determined by the clearance
between the ABS rotor teeth and the ABS sensor, and by the speed of rotation. Sends alternating current signals at frequencies which are proportional to the
rotation speeds of each wheel to the ABS electronic control unit (ABS-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
ABS DTC SET CONDITIONS The ABS-ECU monitors the signals from each ABS sensor while the vehicle is
being driven. If any faults below are found in these sensor signals, the ECU will set
the relevant diagnostic trouble code.
Missing sensor signal Sensor signal, which will not be created under normal operation Significant difference among the ABS sensor signals

CIRCUIT OPERATION
The ABS-ECU contains the power supply circuit (terminal 1) for the solenoid
valve. The solenoid valve is energized by the valve relay, which is
incorporated in the ABS-ECU. The valve relay, which is incorporated in the ABS-ECU, is always energizing
the solenoid valve unless the initial check is in progress when the ignition
switch is turned on. The ABS-ECU activates the solenoid valve by turning on its driving transistor.
ABS DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below.
The solenoid valve is not energized even after the ABS-ECU has turned on the
driving transistor (Open circuit is present in the power supply circuit to the
ABS-ECU solenoid valve, or the valve relay has failed). The solenoid valve is not energized even after the ABS-ECU has turned on the
driving transistor (Open circuit is present in the solenoid valve circuit inside
the ABS-ECU, or the valve relay has failed). After the ABS-ECU has turned off the driving transistor, the solenoid valve
still remains energized (short in the solenoid valve circuit). When a solenoid valve failure is detected
