ABS does not operate when speed is 10 km/h or lower.
1. CHECK ABS WARNING LAMP DISPLAY
Make sure that the warning lamp turns off approximately 1 second after the key switch is turned on or when
driving.
OK or NG
OK >> GO TO 3. Check wheel sensor and sensor rotor in BRC-43, "Symptom 1: ABS Works Frequently"

NG >> Perform self-diagnosis. Refer to BRC-28, "
SELF-DIAGNOSIS" .
Symptom 5: Pedal Vibration and ABS Operation NoiseEFS004HN
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves (Approx. 50 mm or more)

When pulling away just after starting engine (Approx. 10 km/h or more)
1. SYMPTOM CHECK 1
Check if pedal vibration or operation sounds occur when the engine is started.
OK or NG
OK >> GO TO 2.
