Detection Condition

WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.

DTCs P0622, P1244, P1245, or P1246 indicates Generator Load Input (GLI) is not within a calibrated limit for a calibrated amount of time. GLI signal is sent to the PCM from voltage generator/regulator and is a variable frequency duty cycle. GLI signal is used by PCM to determine generator load on engine. As generator load increases, PCM will adjust idle speed accordingly.
