C1185
C1185 ICC UNITDescription
When the force applied to brake pedal exceeds a certain level, the brake assist is activated and generates a greater braking force than that of a conventional brake booster, even with light pedal force. When the ICC preview function identifies the need to apply the sudden brake by sensing the vehicle ahead in the same lane and the distance and relative speed from it, it applies the brake pre-pressure before driver depresses the brake pedal and improves brake response by reducing its free play.

Diagnosis Procedure
INSPECTION PROCEDURE
1.SELF-DIAGNOSIS RESULT CHECK
Perform self-diagnosis of ICC unit.
Are self-diagnosis result items displayed?
YES >> After checking and repairing the applicable item, perform ICC unit self-diagnosis again.
NO >> GO TO 2
2.CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector and the ICC unit connector and check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair or replace as necessary.
3.ICC UNIT CIRCUIT INSPECTION
1. Measure the continuity between ABS actuator and electric unit (control unit) connector E125 and ICC unit connector B13.
2. Measure the continuity between ABS actuator and electric unit (control unit) connector E125 and body ground.
Is the inspection result normal?
YES >> Replace ABS actuator and electric unit (control unit).
NO >> Repair or replace harness or connector.
Special Repair Requirement
1.ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
Always perform neutral position adjustment for the steering angle sensor when replacing the ABS actuator and electric unit (control unit). Refer to BRC-8, "ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION: Description". Testing and Inspection
>> GO TO 2
2.CALIBRATION OF DECEL G SENSOR
Always perform calibration of decel G sensor when replacing the ABS actuator and electric unit (control unit). Refer to BRC-9, "CALIBRATION OF DECEL G SENSOR: Description". Service and Repair
