This function allows user to check for proper operation of output circuits or devices, which PCM cannot internally recognize. DRB allows PCM to activate these outputs or devices, allowing an observer to verify proper operation.

Most tests available in this mode provide an audible or visual indication of device operation (click of relay contacts, spray fuel, etc.). With exception of an intermittent condition, if a device functions properly during its test, it can be assumed that device, wiring and its driver circuit are functioning properly.
