    Pull up the instructions on the FSM. Apparently its very easy.

    The decel sensor is located under the dash, right abouts at the steering column and the center trim, it just in bolts right off.

    You just hook up a multi meter and tilt it in different directions to simulate the different tilts and angles achieved when braking and turning. Different angles will signify an open /closed circuit .

    The manual tell you exactly what to look for and at what angle.

    If your getting the 32 & 44, I doubt its the decel sensor, but I doesn't hurt to test it considering how easy it is.

    Here's the instructions...

    Yotaco98 thanks
    Yes i had to look at all data it had better instructions than Mitchell. I checked and had someone double check it. Called toyota it was a $1000 plus for sensor lol. I dont think it the sensor either. Im leaning more toward abs ecu or broke wires. Im going to nite and ohm out wires from sensors to computer. Then it cant leave much else. Im a mechanic but aint worked on many yo yo's. They are a different breed in some things. I checked sensors rings yesterday they all intacted and look like they are in line with sensor. What do u think it is?? Hope all this headache getting my abs working helps someone else.
