VSC/TRAC issues post-lift?
Just got a 1.75” suspension lift installed on my 2001 Sequoia along with new front ball joints, and immediately afterward I started having VSC/TRAC issues.
Symptoms:
- VSC/TRAC light flashes around 5–10 mph. The truck cuts throttle unless I push hard through it, when I do, I hear/feel a click and a lunge. Light turns off and then the truck drives normally.
- Occasionally the ABS system applies briefly at very low speed while driving straight, and when I’m already braking (think at a red light). It’s the same function of when I take a highway curve too fast, the truck brakes for me.
- Alignment has already been done afterward (attached alignment sheet in comments), they weren’t able to do caster.
The truck otherwise drives fine mechanically. No weird drivetrain noises, no major pulling, etc.
The lift shop thinks it may be related to the steering angle sensor / zero-point calibration and suggested taking it to Toyota. Their computer wasn’t able to reset it. I also checked visible ABS/wheel speed sensor wiring and didn’t notice anything obviously broken or stretched.
Has anyone had this happen after a mild lift on a Gen 1 Sequoia/Tundra?
Did it end up being:
- steering angle sensor calibration?
- yaw sensor?
- wheel speed sensor wire?
Would appreciate any advice before I take it to the dealer. Hoping to get this resolved ASAP. Pics from after and before lift.
