Quick question. Does anyone else hear a sound like ABS brake pump,s from the drivers side under the steering area? I have this sound that sounds like some type of compression happening. Any help would be appreciated.

Well, considering the fact that the ABS pump is directly in front of the steering wheel in the engine compartment, that's probably the noise. It cycles at times(normally after startup) to self-test.

Yea, I hear it too.

I not only hear it at start up but when i am driving or turning etc. Is this normal to hear this sound this much from the ABS pump?

The power assist in the H3 comes from the motor that pressurizes an accumulator to supply brake system boost, versus a vacuum cylinder as used on most other vehicles. This pump will cycle on an off to charge the accumulator whenever required, not just during ABS operation. (The accumulator is the round cylindrical item to the left of the brake master cylinder.)
During ABS operation, it will also run, as well as you will hear the clicking of the solenoids inside the BPMV cycling pressure to the wheels cylinders, as required. |
