ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

*1: Confirm tire pressure is standard value.
*2: Refer to “valve operation” in 

BRC-14, "System Description"

   for valve operation of each valve.

*3: Refer to 

BRC-14, "System Description"

 for ON/OFF conditions of each warning lamp and indicator lamp.

VDC FUNCTION, TCS FUNCTION AND BRAKE LIMITED SLIP DIFFERENTIAL (BLSD) FUNCTION

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 and brake limited slip dif-
ferential (BLSD) function. The vehicle status becomes the same as models without VDC function, TCS func-
tion and brake limited slip differential (BLSD) 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 and brake limited slip differential (BLSD) function. The vehicle status becomes the same as models
without VDC function, TCS function, ABS function and brake limited slip differential (BLSD) 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
function, TCS function, ABS function, EBD function and brake limited slip differential (BLSD) function. The
vehicle status becomes the same as models without VDC function, TCS function, ABS function, EBD function
and brake limited slip differential (BLSD) function.

DIAGNOSIS AND REPAIR WORK FLOW

Work Flow

INFOID:0000000009752907

DETAILED FLOW

1.

INTERVIEW FROM THE CUSTOMER

Clarify customer complaints before inspection. First of all, perform an interview utilizing 

BRC-59, "Diagnostic

Work Sheet"

 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 

BRC-46, "Fail-

safe"

.

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 SELF-DIAGNOSIS

With CONSULT

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.

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-49, "DTC Inspection Priority Chart"

 [ABS actuator and electric unit (control unit)].

Is any DTC detected?

YES

>> GO TO 5.

NO

>> Check harness and connectors based on the information obtained by interview. Refer to 

GI-46,

"Intermittent Incident"

.

5.

REPAIR OR REPLACE ERROR-DETECTED PART

• Repair or replace error-detected parts.
• Reconnect part or connector after repairing or replacing.
• When DTC is detected, erase self-diagnostic result for “ABS”.

>> GO TO 7.

6.

IDENTIFY ERROR-DETECTED SYSTEM BY SYMPTOM DIAGNOSIS

Estimate error-detected system based on symptom diagnosis and perform inspection.
Can the error-detected system be identified?

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.
