C1A00 CONTROL UNIT

Description

INFOID:0000000005501785

ICC sensor integrated unit function description
• It detects the reflected light from the vehicle ahead by irradiating a laser forward. It calculates the vehicle dis-

tance from and relative speed with the vehicle ahead depending on the detected signal. 

• It outputs the brake fluid pressure command signal to the brake booster control unit and the accelerator

pedal feedback force control signal to the accelerator pedal actuator depending on the signal from various
sensors and switches via ITS communication.

Check if the “C1A00” is detected as the current malfunction in self-diagnosis results of “ICC”. 

Is “C1A00” detected as the current malfunction?

YES

>> Refer to 

CCS-211, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000005501787

1.

CHECK SELF-DIAGNOSIS RESULTS

Is any DTC detected?

YES

>> Perform diagnosis on the detected DTC and repair or replace the malfunctioning parts. Refer to

CCS-341, "DTC Index"

.

NO

>> Replace the ICC sensor integrated unit. Refer to 

CCS-380, "Exploded View"
