C1A03 VEHICLE SPEED SENSOR

Description

INFOID:0000000000965401

The ICC sensor integrated unit receives the vehicle speed signal (wheel speed) from the ABS actuator and
electric unit (control unit) and the A/T vehicle speed sensor signal (output shaft revolution signal) from TCM
with CAN communication. 
NOTE:
If DTC C1A03 is detected along with DTC U1000 or C1A04, first diagnose the DTC U1000 or C1A04.
• DTC U1000: Refer to 

CCS-78, "Diagnosis Procedure"

.

• DTC C1A04: Refer to 

CCS-33, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000000965403

1.

PERFORM SELF-DIAGNOSIS OF ICC SENSOR INTEGRATED UNIT

1.

Perform self-diagnosis of ICC sensor integrated unit.

2.

Check if DTC “CAN COMM CIRCUIT [U1000]” (DTC 100) or “ABS/TCS/VDC CIRC [C1A04]” (DTC 4)
other than “VHCL SPEED SE CIRC [C1A03]” (DTC 3) 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 A/T VEHICLE SPEED SENSOR

With CONSULT-III

1.

Start engine.

2.

With “DATA MONITOR” of “ICC”, check if “VHCL SPD AT” operates normally.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 4.

4.

PERFORM SELF-DIAGNOSIS OF TCM

1.

Perform self-diagnosis of TCM.

2.

Repair or replace applicable item. Refer to 

TM-189, "DTC Index"

.

>> GO TO 6.

5.

REPLACE ICC SENSOR INTEGRATED UNIT

1.

Replace ICC sensor integrated unit.

DTC No.

VHCL SPEED SE CIRC

If the vehicle speed signal (wheel speed) from the 
ABS actuator and electric unit (control unit) and 
the A/T vehicle speed sensor signal (output shaft 
revolution signal) from TCM, received by the ICC 
sensor integrated unit with CAN communication, 
are inconsistent.

• Wheel sensor
• ABS actuator and electric unit (con-

trol unit)

• A/T vehicle speed sensor
• TCM
• ICC sensor integrated unit

2.

Adjust laser beam aiming. Refer to 

CCS-7, "LASER BEAM AIMING ADJUSTMENT : Special Repair

Requirement (Preparation)"

.

>> GO TO 6.

6.

CHECK ICC SYSTEM

1.

Erase DTC and perform ICC system action test. Then perform self-diagnosis of ICC sensor integrated
unit. (For the details on the ICC system action test, refer to 

CCS-11, "ACTION TEST : Special Repair

Requirement (Vehicle-To-Vehicle Distance Control Mode)"

).

2.

Check that no abnormal condition is present in the ICC system.

C1A04 ABS/TCS/VDC SYSTEM

Description

INFOID:0000000000965404

• ABS actuator and electric unit (control unit) transmits the vehicle speed signal (wheel speed), the stop lamp

switch signal, and the operation status of the VDC, TCS, and ABS systems to the ICC sensor integrated unit
with CAN communication. 

• ABS actuator and electric unit (control unit) receives the deceleration degree command value signal from the

ICC sensor integrated unit with CAN communication and controls the brake fluid pressure with the ABS
actuator and electric unit (control unit). 

NOTE:
If DTC C1A04 is detected along with DTC U1000, first diagnose the DTC U1000. Refer to 

CCS-78,

"Diagnosis Procedure"

.
