System Operation
- ABS-ECU contains the power supply circuit (terminal No. 26) for the solenoid valve. The solenoid valve is energized by the valve relay, which is incorporated in ABS-ECU.
- ABS-ECU contains the power supply circuit (terminal No. 13) for the pump motor. The pump motor is energized by the motor relay, which is incorporated in ABS-ECU.
- ABS-ECU contains the power supply circuit (terminal No. 7) for ABS-ECU. When the ignition switch (IG1) is turned ON, the voltage is applied to the relay incorporated in ETACS-ECU to turn ON the relay, and the power is supplied from fusible link No. 34 through multi-purpose fuse No. 12.
- When malfunction occurs in ABS-ECU power supply, the communication with scan tool becomes unavailable.
