DCA-400SSV— TROUBLESHOOTING (DIAGNOSTIC LAMP)
The engine controller of this generator diagnoses problems
that arise from the engine control system and the engine
itself. The malfunction can be determined by examining the
flashing pattern of the diagnostic lamp (Figure 69) located in
the control box.

Method of Operation
1. Normally, the diagnostic lamp will be
dimly
lit when the

lit as long as the control switch is left in the
manual position.

flashing pattern on the lamp. This pattern will become
visible once the the reset button on the control box has
been pushed and released. The error code consists of a
series of flashes by the lamp. The error codes are defined
as follows:

simultaneously, the code for each malfunction will flash
one after another in sucession.
5. After all engine related malfunctions have been diagnosed
and corrected, and the generator is operating in a normal
maner the following code (Figure 72) should be displayed
once the reset button is pressed and released
