That has no effect on the TC or ABS whatsoever.
1. WSS (hub/bearing assembly)
2. PMV (pressure modulator valve assembly below the airbox)
3. EBCM (the 'brain')
4. Associated wiring in between.
If TC or ABS fails, it fails in 'failsafe mode' and will not affect normal braking. Vacuum is not part of the system.
Items 2 and 3 are very expensive.
