VSC Light + Cruise Control not working after lift

Hi all,

After getting my Tacoma lifted + an alignment done, my VSC light comes on with an error, and when I try to use my cruise control (even just the standard cruise control, not even the adaptive), it also errors out. Should I try to do the VSC reset on the OBD connector, or do you think that the shop damaged a wheel speed sensor while working on it?

Thank you!

 

It's possible the shop messed up something but without knowing what the code is, we are just guessing. If the VSC/check engine light is on, cruise won't work.

 

I see. Is the process/pins different for resetting the zero point for the VSC on later model 3rd gens, or will existing guides work?

 

My info just shows using the Techstream. Perhaps another user knows if you can use a jumper wire.

 

You need to re-calibrate the VSC system. I know for the 2nd gen you can do it with a paper clip un the obd2 port (i do it with a switch/wire for safety). You need a level surface, working parking brake (need to be applied for the calibration). It's like a 2 minute job.

It's in the FSM for the 2016 Tacoma so i think it's the same procedure as the 2nd gen

 

If the center point calibration doesn't work, I'd look at the wires for the rear ABS. Usually the wires pull out of the connector on the frame above the rear axle. I've seen too many shops drop the rear axle too much and it pulls the pins out of the connector. You will have faults for rear speed sensors open/no signal. Or maybe the shop unplugged the connector and forgot to plug it in, or didn't get it fully connected.

 

No go on shorting pins, there's not even a wire in one of them. Any ideas? OBD scanner maybe?

 

Check wires at rear axle and front wheel speed sensor wires.

 

Most likely when they did the alignment, they skipped a tooth on the rack and pinon. It can be fixed.

 

I checked the wires; it seemed like everything was plugged into the sensor head tight. I felt around on the rear tire sensors and didn't seem to find any plugs other than the ones on the heads. I might pull the plugs off and make sure there aren't any bent pins and see if the wires are actually connected to the pins.

Is there an easy way to check this myself? I did notice that my steering wheel is very slightly cocked to the right when my tires are straight

 

No, there is no easy way to check this
Need to take it back to the alignment shop.

 

The steering shaft should have never come off during lift install. I've done several, and at no point have I needed to do this. The most likely issue is what I stated earlier. They most likely did not unplug the harness for the rear axle at the frame crossmember. And when the rear was lowered, it pulled the wires out of the connector.

 

I have lifted my truck with 3 different lifts, bilsttien 5100 front and rear, to icon 2.5 with maxtrac spindles, back to stock suspension, then back to icon 2.5 and maxTrac spindles. I have had this exact situation happen twice.... ohhh and my rack and pinon broke and is now going out again, leaking at the boots.
Steering shaft was never disconnected except when the rack was replaced the first time.
Edit...plus 7 years on this forum and owning a 2nd Gen and a 3rd gen, I am pretty sure I know a few things

you already have the issue in front of you, if the steering wheel is off, then the truck thinks it is turning, but the truck is smart , it can see the wheels speeds and knows you cannot be turning when the wheels speeds all are = , so the truck is protecting it'self and you - taking away features not required to go from point a to point b ... which in this case ... point a is where you are - point b is a good alignment shop , if they properly set the toe with the steering wheel straight , your problem will be solved ---- they may need to 0 point calibrate the steering angle sensor, but until the steering wheel angle and the angle of the front wheels are the same, you are going to have issues. Good luck
