    Exclamation Success!!! VSC and Lift issue Fix Confirmed!

    Ok you guys, ever since I put on the Bilstein 5100's I was having issues with the VSC going off around corners unless I went really slow. After having the Zero Point cal done and it didn't fix the problem I was getting upset. After looking into this further, the fix is quite simple. Thanks to Sparks for giving me the diagram for the VSC sensor. The problem lies with the Yaw and deceleration sensor. It seems to be very sensitive to any nose up condition. Here is what I did. I removed the sensor and shimmed up the back side so it would have a slope, nose down, to it, to simulate not having the front lift. I re-calibrated the Zero Point per the pdf file and bam, no more VSC problem. I was taking the corners squealing the tires and no VSC engagement. To get to the sensor you need to remove the center console. I put 3 of the washers shown on the back side. Be sure to tighten the front first, then the back. I have an 07 Crewmax 4x4, but I imagine all others are the same. Hopefully this will work for you guys too!

    I was going to make an appointment today to have the zero point calibration done again. I get the same thing when pulling a trailer and going around corners. This is awesome news! Thanks!

    Did you re-calibrate using the SST method, if so where is that located?

    yes, just use a jumper wire and the connector is under the dash next to the TPMS button.

    That's it. No wonder my truck feels quicker with the factory rake compared to when I lower the rear. I have Alcan soft springs with Firestone airbags. With the airbags at 5 psi, the rear is lower than stock. The truck feels sluggish on acceleration. I thought it was just aerodynamics but I'm also thinking the truck has accelerometer and yaw sensor which maybe interpreting the truck is loaded.

    Do you disable nannies while you feel this sluggishness?

    Just a quick update, went for a long drive today and noticed that sharp right hand curves there was still a little bit of sensitivity of the VSC. There was none on the left hand curves. When I got home I check the sensor again and noticed it was not level from left to right. So I ben the bracket to make it level side to side and went back out and the right hand sensitivity was gone. It did not change the left hand sensitivity. So what I am suggesting is to make sure the side to side is not skewed when you do this mod.

    The nannies are always off when I drive except for really short ones like reparking the truck. I got used to the routine of turning the nannies off as soon as I start the truck. I also use "S" mode 99% of the time and have been using 91 octane gas for years now. The sluggishness is not too much though. It's like putting 500 lbs in the bed. I guess the computer can relearn after sometime, but I just put the factory rake back on. It's quieter on the highway(less wind noise) and also on the track at 118 MPH.

    Just a thought about why it may have been occuring with rights more than lefts. Since we drive on the right side of the road, the turn radius is usually shorter for a right hand turn, if it is a two lane road/ramp. That makes for higher G's given the same speed for that turn radius. Or, as you said, the sensor wasn't balanced. Could be a sway bar issue as well I assume.

    I am thinking about trying this mod on my 2006 Tundra before they mount the new (larger) tires, and then have them zero balance the VSC system. Is the unit under the center console like it is in the '07 and ups, and what size washers did sknaus use? I wish the truck had a VSC defeat button, so I could just kill the thing all together.

    They charged me $110 which includes tax. It took them 5 minutes. Those bastards!

    Does that washer mod really work? Should I do that right after installing my lift/tires to prevent VSC engagement?
