C1A27 ECD POWER SUPPLY CIRCUIT

C1A27 ECD POWER SUPPLY CIRCUIT

Description

INFOID:0000000000965446

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. 

NOTE:
If DTC C1A27 is detected along with DTC U1000, U0415 or U0121 first diagnose the DTC U1000, U0415 or
U0121.
• DTC U1000: Refer to 

CCS-78, "Diagnosis Procedure"

.

• DTC U0415: Refer to 

CCS-76, "Diagnosis Procedure"

.

• DTC U0121: Refer to 

CCS-70, "Diagnosis Procedure"

.

CAN CIR 2 [U0121]” (DTC 127) other than “ECD PWR SUPLY CIR [C1A27]” (DTC 27) is detected.

Is any DTC detected?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

DIAGNOSIS FOR DETECTED DTC

Perform diagnosis on the detected DTC and repair or replace the applicable item. Refer to 

CCS-91, "DTC

Index"

.

>> GO TO 6.

3.

CHECK POWER SUPPLY CIRCUIT OF ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

Check power supply circuit of ABS actuator and electric unit (control unit). Refer to 

BRC-36, "Diagnosis Proce-

dure"

.

Is the inspection result normal?

YES

>> GO TO 5.
