I have checked this Opel Frontera B 2000. Our DS708 will test the systems below: engine, body(anti-theft, central door lock, immobilizer), transmission, infortainment.
ABS Module on this model is going to very hard the only tool I was lucky to use was on this vehicle for ABS system Autocom and if I remember well it was 8/9 years ago so, if you can get the Autocom try it
