CONSULT- II Functions (ABS)NFS00023
CONSULT-III MAIN FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
Self-DiagnosisNFS000HD
OPERATION PROCEDURE
1. Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.
HOW TO ERASE SELF-DIAGNOSIS RESULTS
1. 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 and brake warning lamp turn
OFF.
CAUTION:
If memory cannot be erased, perform applicably diagnosis.

When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp
and brake warning lamp will not turn OFF even when the system is normal unless the vehicle is driving
at approximately 30 km/h (19 MPH) or more for approximately 1 minute.

Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake
fluid level switch operation (when brake fluid is insufficient).

WARNING LAMP ON/OFF TIMING
×: ON –: OFF
Note 1:Brake warning lamp will turn on in case of operating parking brake (switch turned on) or of actuating brake fluid level switch
(brake fluid is insufficient).
Basic InspectionNFS0004C
BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill the brake fluid.
2. Check brake tubes or hoses and around VDC actuator for leaks. If there is leaking or oozing fluid, check
the following items.

If VDC actuator connection is loose, tighten the piping to the specified torque and re-conduct the leak
inspection to make sure there are no leaks.

If there is damage to the connection flare nut or VDC actuator screw, replace the damaged part and re-
conduct the leak inspection to make sure there are no leaks.

When there is fluid leaking or oozing from a part other than VDC actuator connection, if the fluid is just
oozing out, use a clean cloth to wipe off the oozing fluid and re-check for leaks. If fluid is still oozing out,
replace the damaged part.

When there is fluid leaking or oozing at VDC actuator, if the fluid is just oozing out, use a clean cloth to
wipe off the oozing fluid and re-check for leaks. If fluid is still oozing out, replace the VDC actuator body.
CAUTION:
VDC actuator cannot be disassembled.
3. Check the brake pad degree of wear. Refer to BR-26, "
PAD WEAR INSPECTION" in “Front Disc Brake”
and BR-39, "
PAD WEAR INSPECTION" in “Rear Disc Brake”.
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure the battery positive cable, negative cable and ground connection are not loose. In addition, check
the battery voltage to make sure it has not dropped.
ABS WARNING LAMP, VDC OFF INDICATOR LAMP, SLIP INDICATOR LAMP INSPECTION
1. Make sure ABS warning lamp, VDC OFF indicator lamp (when VDC OFF switch is OFF), and SLIP indica-
tor lamp turns ON approximately 1 second when the ignition switch is turned ON. If they do not, check the
VDC OFF indicator lamp and then VDC OFF switch. Refer to BRC-122, "
VDC OFF SWITCH" . Check
CAN communications. Refer to “CAN Communication Inspection”. If there are no errors with VDC OFF
switch and CAN communication system, check combination meter. Refer to BRC-122, "
CAN Communica-
tion System" .
