ACTUATOR TEST Mode

This mode allows the user to check for proper operation of output circuits or devices which the SBEC cannot internally recognize. DRB-II allows SBEC to activate these outputs or devices, allowing an observer to verify proper operation.

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, the device, wiring and its driver circuit are presumably functioning properly.
