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, 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:
• “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.

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.
