check for damaged ABS sensor which is a ring behind the hub bearing. if its a second hand part chances are it was removed because this is broken. also when was the enchine last serviced? as it may be due, my advice to you is to find a specialist qualified technician to diagnose your automobiles malfunctioning ABS

The ABS sensor is incorporated into the hub assembly. Carefully inspect the wiring going to the hub assembly. Since the wiring at the front wheels are always moving and flexing whenever you turn the steering wheel they're prone to wear and breakage. The trac off light is on because the Traction Control and ABS work together. So when the computer detects a problem with one system, both are disabled. If the wiring going to the hub assembly is ok, you may have been unlucky and got a defect. Unfortunately it happens sometimes. As for the service engine soon light being on I can't see how that's related. Unless one of the engine sensors got unplugged accidentally. Best to scan the PCM for trouble codes to see what's going on there. Most auto parts stores will do the scan for free. HTH. -Jim
