Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
ACTUATOR TESTS Mode
This mode on DRB-II allows technician to actuate injectors, fuel pump, purge control, fuel pressure solenoid and wastegate.
Most of the tests available in this mode provide an audible or visual indication of device operation (click of relay contacts, spray fuel, etc.). With the exception of an intermittent condition, if a device functions properly during its test, it can be assumed that the device, wiring and its driver circuit are functioning properly.
