Diagnostic Aids

With the ignition ON, engine OFF, the voltage measured with a DVOM on circuit No. 25 at the generator with the connector disconnected should read about 5 volts. The voltage may rise to around 5.8 volts with engine running.

An intermittent short to ground on circuit No. 25 will set this DTC. An open or short to voltage on circuit No. 25 will NOT.

A generator that is not charging will pull circuit No. 25, through resistance, to ground and set this DTC. The voltage on circuit No. 25 with the circuit intact will read between 1.0-1.5 volts when this condition occurs.
