TROUBLE DIAGNOSIS
Note 1: Confirm tire pressure is normal.
Note 2: ON/OFF timing of ABS warning lamp
ON: Approx. Within 2 seconds after ignition switch is turned ON, or when a malfunction is detected.
OFF: Approx. 2 seconds after ignition switch is turned ON (when sy
stem is in normal operation) and VDC/TCS function is not activated.
Note 3: ON/OFF timing of VDC OFF indicator lamp
ON: Approx. Within 2 seconds after ignition switch is turned ON, or when a malfunction is detected and VDC OFF switch is ON.
OFF: Approx. 2 seconds after ignition switch is turned ON (when system is in normal operation.) And when VDC OFF switch is OFF.
Note 4: ON/OFF timing of SLIP indicator lamp
ON: Approx. Within 2 seconds after ignition switch is turned ON, or when a malfunction is detected and VDC/TCS function is activa ted
while driving.
OFF: Approx. 2 seconds after ignition switch is turned ON (when sy stem is in normal operation) and VDC/TCS function is not activated.
Flashing: VDC/TCS function is active during driving
Note 5: Only AWD models.
Note 6: Serves as EBD warning lamp.
CONSULT-III Functions (ABS)INFOID:0000000001327671
CONSULT-III MAIN FUNCTION
CONSULT-III can display each diagnostic item us ing the diagnostic test modes shown following.
Self-DiagnosisINFOID:0000000001327672
OPERATION PROCEDURE
Before performing the self-diagnosis, start engine and driv e vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute.
ERASE MEMORY
After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1
minute as the final inspection, and make sure that the ABS warning lamp, VDC OFF indicator lamp, SLIP indi-
cator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicably diagnosis.
NOTE:
 When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,
VDC OFF indicator lamp, SLIP indicator lamp and br ake waning lamp will not turn OFF even when the sys-
tem is normal unless the vehicle is driving at approxim ately 30 km/h (19 MPH) or more for approximately 1
minute.
 Brake warning lamp will turn ON in case of parki ng brake operation (when switch is ON) or of brake fluid
level switch should not stay “ON” position.
 VDC OFF switch should not stay “ON” position.

Diagnostic test mode Function
WORK SUPPORT This mode enables a technician to adjust some devices faster and more accurately by following the
indications on CONSULT-III.
SELF-DIAG RESULTS Self-diagnostic results can be read and erased quickly.
DATA MONITOR Input/Output data in the ABS actuator and electric unit (control unit) can be read.
CAN DIAG SUPPORT MNTR The results of transmit/receive diagnosis of communication can be read.
ACTIVE TEST Diagnostic Test Mode in which CONSULT-III drives
some actuators apart from the ABS actuator and
electric unit (control unit) and also shifts some parameters in a specified range.
FUNCTION TEST Performed by CONSULT-III inst ead of a technician to determine whether each system is “OK” or “NG”.
ECU PART NUMBER ABS actuator and electric unit (control unit) part number can be read.
