ABS and other warning lights on and no speedo!

None of the wheel sensor have been tested. Can this be done with a Tech II scanner? Or how can the wheel sensors be tested?

Tech II should work, ABS selected > have helper drive vehicle while wheel speed sensor live data is viewed .. ALL sensors should read same. .. Sensors can also be tested with ohm meter .. Wheel speed sensor output signal critical to speedometer operation as well as ABS! .. Car is 16 + years old now .. Good idea to 'closely' inspect sensor wiring and wire connectors!! .. Good luck with it.
