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

CIRCUIT OPERATION
The ABS-ECU contains the power supply circuit (terminal 19) for the pump
motor. The pump motor is energized by the motor relay, which is incorporated
in the ABS-ECU. The motor relay, which is incorporated in the ABS-ECU, is always off unless
the motor solenoid valve check is activated when the vehicle is started. The ABS-ECU activates the pump motor by turning on the ECU built-in motor
relay when the ABS is working.
ABS DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below.
DTC C1266: Motor system (seizure)
If the ABS-ECU determines that the pump motor is not running smoothly (i.e.
motor seizure) after the motor relay is turned off, this DTC will be set.
DTC C1273: Motor relay problem (stuck off) If the ABS-ECU determines that the motor is not running after the motor relay
is turned on, the ECU determines that the motor relay is stuck off, and sets this
DTC.
DTC C1274: Motor relay problem (stuck on) If the ABS-ECU determines that the motor is running after the motor relay is
turned off, the ECU determines that the motor relay is stuck on, and sets this
DTC. CAUTION: If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set. Prior to
this diagnosis, diagnose the CAN bus lines.
