    Just had the vac light blinking and traction control light on solid.
    Let me back up, had a small lift installed and the wire from the sensor to inside the engine bay damaged. Which caused the abs and vsc blinking and trac light on solid. Did some reasearch on the interweb and YouTube.

    After you repaired the problem and drive it a few miles. If only the abs goes out. Then, you have to calibrate the abs system. My scan tool didn't have the ability to do so. I took it to my mechanic buddy and he checked it out and re calibrated the system.

    there is a procedure in the manual, or maybe it was a TSB to calibrate the VSC and you just had to short two pins on the OBDII plug in a sequence. O2 sensor failure is enough to trigger the fault so you run right down to the stealership in a panic.
