C1A27 ECD POWER SUPPLY CIRCUIT
Description
INFOID:0000000003130085
ECD (ELECTRONICALLY CONTROLLED DECELERATION)
• Receives deceleration degree commandment value signal from ICC sensor integrated unit, and controls
brake fluid pressure with the motor [built in ABS actuator and electric unit (control unit)].
• ECD control-related signals are transmitted by ABS actuator and electric unit (control unit) to ICC sensor
integrated unit with CAN communication.
