Bmw Inpa 301 Dis Sss And Diag Head With Instuctions Link

The "Smart Mechanic." DIS is the heavy lifter. This is a fully graphical, wizard-based system. You input your VIN, and it knows every single module on your car. It guides you through troubleshooting trees. For example, if you have an ABS light, DIS will ask you to press the brake pedal, measure the voltage, ask you to inspect the sensor, and guide you step-by-step to the solution. It is the closest thing to having a dealership technician looking over your shoulder. Verdict: The best feature of the suite. Perfect for complex troubleshooting where you don't know the root cause.
