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.
