Re: ABS light / Front wheel bearing 740-760 90

The ABS system on that year model doesn't have fault diagnosis code feature.

If it's a wagon with solid rear axle the wire from car to axle is subject to motion with every bump and will fatigue and break inside insulation. This usually is no sooner than 100 K miles unless the car is driven on poor roads a lot. If it were the cable it would predictably do it on bumps. If there is a severe build up of metallic particles on front sensors that can make light come on. If your wheel bearing has expelled grease that may have bulit up on sensor and made it retain the metal pad wear particles. That might be the place to look first. A bent pulse wheel ( part of hub and runs next to sensor to create the signal , looks like a gear) can do the same. The system is designed to be a little forgiving when the signals from wheels are not equal as this could be due to normal things like having the mini-spare on car. If the signal is too different then the ABS lamp will light .
