CONSULT Function (ABS)

INFOID:0000000009479252

FUNCTION

CONSULT can display each diagnostic item using the following direct diagnostic modes.

SELF DIAGNOSTIC RESULT

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, VDC OFF indicator lamp,

SLIP indicator lamp and brake warning lamp turn OFF.

CAUTION:

If memory cannot be erased, perform applicable 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 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 approxi-

mately 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).

• VDC OFF switch should not stay “ON” position.
