P0907 Fault Code

[spooltime]

I've been getting a P0907 fault code reported for the electrical system, which is a load management issue that supposedly is triggered when there's a voltgage drop.   I replaced the battery, and my voltgage gauge shows a nice, steady 13.9 - 14.1 volts while the engine is running, so it seems like the alternator is okay.  What other diagnositc steps can I take before I surrender and have my dealer's service department look into it?

I sent you some troubleshooting tips - via PM.

Thanks very much,  Time to dig out the multimeter.

Have you cleared the low voltage codes in all modules? Does the code return after battery replacement? What year is the vehicle, does it have two batteries?

I replaced the battery with the big Interstate H9 battery and cleared all faults using Durametric.  The electrical system fault returned, showing only part number "11" (with no fault code), so I contacted Durametric support and they sent me a new electrical system diagnostic file to try.  When I used the new software file, it returned with the 0907 fault, but still only showed part number 11 as being the source of the fault.  I contacted them again and they said they're still working on getting the identification aspect of the electrical system diagnostic to report proper values.  But as least with the fault code and the diagnostic steps I received, I have some more possibilities to investigate.  Any other suggestions?
