Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pedal Feel Characteristics
During ABS stopping or LTCS acceleration, solenoid valve clicking and pump motor operation may be heard and brake pedal vibration/pulsation may be felt. During ABS/LTCS operation, the master cylinder is isolated from wheel brakes, producing a hard pedal feel. A slight brake pedal drop may be felt when ABS/LTCS is shut off.
The system may detect wheel lock-up or slip and activate ABS/LTCS under the following conditions: braking or accelerating on bumpy surface or when sand, gravel or other loose debris is on the road. Under such conditions, hard pedal feel and loss of deceleration/acceleration may be experienced.
Hard pedal feel will not make warning lights come on or set fault message. When investigating a hard pedal feel or excessive system noise, inspect sensor and tone wheel teeth for chips, damaged sensor pole tips, and excessive tone wheel runout or gap.
