From the 2012 Workshop Manual...

 

Pinpoint Test D - DTC P0625 or P0626 [Introduction - Full procedure is linked below]


Refer to Wiring Diagrams Cell 12 , Charging System for schematic and connector information [Pictured here and also linked below]...

Normal Operation [Emphasis added]

The PCM monitors the generator output via the generator monitor (GENMON) circuit. If the PCM cannot read the GENMON circuit due to an open or short to ground, when the engine rises above approximately 2,000 rpm, the generator defaults to a steady voltage of approximately 13.5 volts and the PCM sends a request to the Instrument Panel Cluster (IPC) to illuminate the charging system warning indicator. A GENMON duty cycle of 3% or less indicates a short to ground fault is present and results in DTC P0625 setting in the PCM. A GENMON duty cycle of 98% or more indicates an open or short to voltage fault is present and results in DTC P0626 setting in the PCM.

  • DTC P0625 (Generator Field Terminal Circuit Low) — The PCM sets this DTC if the GENMON circuit is shorted to ground, the "A" sense circuit is open or the B+ circuit is open. This DTC also sets by a faulted PCM or generator.
  • DTC P0626 (Generator Field Terminal Circuit High) — The PCM sets this DTC if the GENMON circuit is open or shorted to power. This DTC can also be set by a faulted PCM or generator.

This pinpoint test is intended to diagnose the following:

  • Fuse
  • Wiring, terminals or connectors
  • Radial arm adapter
  • Engine, generator and battery grounds
  • Battery
  • Generator
  • PCM
