CAUTION:
Under the following conditions, when brake pedal is lightly depressed (just place a foot on it), ABS is
activated and vibration is felt. However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves [50 mm (1.97 in) or more]

When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1. SYMPTOM CHECK 1
Check if pedal vibration or operation sound occurs when the engine is started.
Does the symptom occur?
YES >> GO TO 2.
NO >> Perform self-diagnosis. Refer to BRC-19, "
OPERATION PROCEDURE" .
2. SYMPTOM CHECK 2
Check symptom when electrical component (headlamps, etc.) switches are operated.
Does the symptom occur when the electrical component (head lamp, etc.) switches are operated?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit (or its wir-
ing), and if there is, move it farther away.

Self-diagnosisNFS000HG
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, TCS OFF indicator lamp,
SLIP indicator 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,
TCS 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).

Note 1: After completing repairs of the shorted sensor circuit, when ignition switch is turned ON, ABS warning lamp turns on. Check that
ABS warning lamp turns off while driving the vehicle at approximately 30 km/h (19 MPH) or more for approximately 1 minute according
to self-diagnosis procedure. In addition, if wheel sensor 2 is displayed for the wheels, check the wheel sensor circuit and also check the
control unit power voltage.
