ACTIVE TEST
The active test is used to determine and identify details of a malfunction, based on self-diagnosis test result
sand data obtained in the DATA MONITOR. In response to instructions from CONSULT-III, instead of those
from ABS actuator and electric unit (control unit) on the vehicle, a drive signal is sent to the actuator to check
its operation.
CAUTION:
• Never perform ACTIVE TEST while driving the vehicle.
• Always bleed air from brake system before ACTIVE TEST.
• Never perform ACTIVE TEST when system is malfunctioning.
NOTE:
• When active test is performed while depressing the pedal, the pedal depressing stroke may change. This is
not a malfunction.
• “TEST IS STOPPED” is displayed approx. 10 seconds after operation start.
• When performing active test again after “TEST IS STOPPED” is displayed, select “BACK”.
• ABS warning lamp and brake warning lamp may turn ON during active test. This is not a malfunction.

ESP FUNCTION, TCS FUNCTION AND BRAKE LIMITED SLIP DIFFERENTIAL (BLSD) FUNCTION
ESP 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 ESP function, TCS function and brake limited slip dif-
ferential (BLSD) function. The vehicle status becomes the same as models without ESP 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 ESP 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 ESP function, TCS function, ABS
function and brake limited slip differential (BLSD) function. The vehicle status becomes the same as models
without ESP 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 ESP 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 ESP
function, TCS function, ABS function, EBD function and brake limited slip differential (BLSD) function. The
vehicle status becomes the same as models without ESP function, TCS function, ABS function, EBD function
and brake limited slip differential (BLSD) function.

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-III.
Perform self-diagnosis for “ABS”.
Is DTC detected?
YES
>> Record or print self-diagnosis results and GO TO 4.
NO
>> GO TO 6.
4.
RECHECK THE SYMPTOM
With CONSULT-III.
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-141, "DTC Inspection Priority Chart"
[ABS actuator and electric unit (control unit)].
