VDC warning lamp in combination meter turn ON when a malfunction occurs in system [ABS actuator and
electric unit (control unit)]. The control is suspended for VDC function, TCS function, Brake limited slip differ-
ential (BLSD) function, Brake assist function, hill start assist function and Brake force distribution function. The
vehicle status becomes the same as models without VDC function, TCS function, Brake limited slip differential
(BLSD) function, Brake assist function, hill start assist function and Brake force distribution function. However,
ABS function and EBD function are operated normally.
ABS FUNCTION
ABS warning lamp and VDC warning lamp in combination meter turn ON when a malfunction occurs in system
[ABS actuator and electric unit (control unit)]. The control is suspended for VDC function, TCS function, ABS
function, Brake limited slip differential (BLSD) function, Brake assist function, hill start assist function and
Brake force distribution function. The vehicle status becomes the same as models without VDC function, TCS
function, ABS function, Brake limited slip differential (BLSD) function, Brake assist function, hill start assist
function and Brake force distribution function. However, EBD function is operated normally.
NOTE:
ABS self-diagnosis sound may be heard the same as in the normal condition, because self-diagnosis is per-
formed when ignition switch turns ON and when vehicle initially starts.
EBD FUNCTION
ABS warning lamp, brake warning lamp and VDC warning lamp in combination meter turn ON when a mal-
function occurs in system [ABS actuator and electric unit (control unit)]. The control is suspended for VDC

DETAILED FLOW
1.
INTERVIEW FROM THE CUSTOMER
Clarify customer complaints before inspection. First of all, perform an interview utilizing
and reproduce the symptom as well as fully understand it. Ask customer about his/her complaints
carefully. Check symptoms by driving vehicle with customer, if necessary.
CAUTION:
Customers are not professional. Never guess easily like “maybe the customer means that...,” or “
maybe the customer mentions this symptom”.
>> GO TO 2.
2.
CHECK SYMPTOM
Reproduce the symptom that is indicated by the customer, based on the information from the customer
obtained by interview. Also check that the symptom is not caused by fail-safe mode. Refer to
.
CAUTION:
When the symptom is caused by normal operation, fully inspect each portion and obtain the under-
standing of customer that the symptom is not caused by a malfunction.
>> GO TO 3.
3.
PERFORM THE SELF-DIAGNOSIS
With CONSULT
1.
Turn the ignition switch OFF
→
ON.
CAUTION:
Be sure to wait of 10 seconds after turning ignition switch OFF or ON.
2.
Repeat step 1 two or more times.
3.
Perform self-diagnosis for “ABS”.
Is DTC detected?
YES
>> Record or print self-diagnosis results and freeze frame data (FFD). GO TO 4.
NO
>> GO TO 6.
4.
RECHECK THE SYMPTOM
With CONSULT
1.
Erase self-diagnostic results for “ABS”.
2.
Turn the ignition switch OFF
→
ON
→
OFF.
CAUTION:
Be sure to wait of 10 seconds after turning ignition switch OFF or ON.
3.
Perform DTC confirmation procedures for the error-detected system.
NOTE:
If some DTCs are detected at the some time, determine the order for performing the diagnosis based on
BRC-52, "DTC Inspection Priority Chart"
Is any DTC detected?
YES
>> GO TO 5.
NO
>> Check harness and connectors based on the information obtained by interview. Refer to
.
5.
REPAIR OR REPLACE ERROR-DETECTED PART
1.
Repair or replace error-detected parts.
2.
Reconnect part or connector after repairing or replacing.
3.
When DTC is detected, erase self-diagnostic result for “ABS”.

FINAL CHECK
With CONSULT
1.
Check the reference value for “ABS”.
2.
Recheck the symptom and check that the symptom is not reproduced on the same conditions.
Is the symptom reproduced?
YES

NO
>> Inspection End.
Diagnostic Work Sheet
INFOID:0000000010428738
Description
• In general, customers have their own criteria for a problem. Therefore, it is important to understand the
symptom and status well enough by asking the customer about his/her concerns carefully. To systemize all
the information for the diagnosis, prepare the interview sheet referring to the interview points.
• In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.

Refer to the table below to determine if adjustment of steering angle sensor neutral position is required.
×
: Required –: Not required
Work Procedure
INFOID:0000000010428741
ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
CAUTION:
To adjust neutral position of steering angle sensor, make sure to use CONSULT.
(Adjustment cannot be done without CONSULT).
1.
ALIGN THE VEHICLE STATUS
Stop vehicle with front wheels in straight-ahead position.
>> GO TO 2.
2.
PERFORM THE NEUTRAL POSITION ADJUSTMENT FOR THE STEERING ANGLE SENSOR
1.
On the CONSULT screen, touch “WORK SUPPORT” and “ST ANG SENSOR ADJUSTMENT” in order.
2.
Touch “START”.
CAUTION:
Do not touch steering wheel while adjusting steering angle sensor.
3.
After approximately 10 seconds, touch “END”.
NOTE:
After approximately 60 seconds, it ends automatically.
4.
Turn ignition switch OFF, then turn it ON again.
CAUTION:
Be sure to perform above operation.
>> GO TO 3.
3.
CHECK DATA MONITOR
1.
Run vehicle with front wheels in straight-ahead position, then stop.
2.
Select “DATA MONITOR”. Then make sure “STR ANGLE SIG” is within 0
±
3.5
°
.
Is the steering angle within the specified range?
YES
>> GO TO 4.
NO
>> Perform the neutral position adjustment for the steering angle sensor again, GO TO 1.
4.
ERASE THE SELF-DIAGNOSIS MEMORY
Erase the self-diagnosis memory of the ABS actuator and electric unit (control unit) and ECM.
