Sensor Circuit

Fig. 3 Sensor Circuit Diagram:

1. Rear brake lock-up control warning light illuminates, and system operation is interrupted: Sensor signals are not input to the ECU, open circuit in G-sensor, pulse sensor or wiring. Check G-sensor and/or pulse generator, refer to COMPONENT TESTING.
2. Rear brake lock-up control warning light illuminates, and system operation is interrupted: Abnormal sensor signal output (rotor deformation). Check G-sensor and/or pulse generator, refer to COMPONENT TESTING.
3. Rear brake lock-up control warning light illuminates, and system operation is interrupted: Noise (interference) is easily picked up, and speed sensor may generate abnormal signals, damaged or disconnected ground of the shielded line. Check ground connection of the shielded line.
