907 load management error

[mbagge01]

I have been getting this error on durametric labled 907 under electrical. I have no CEL.

"Load management operat. on vehicle electrical sys./DME control module - No additional fault status available, test conditions are not-completed, fault is currently active and is not causing a DTC light"

I have read it can be related to a bad battery. I reset it and it keeps coming back The battery in the car is an aftermarket one that I do not think is more than 2 years old. I did test it with a battery tester and it is reading as becoming weak. What kind of car symptoms could I expect. Could a bad battery also cause issues with drivability such as misfires etc.

Fault 907 Load management operation on vehicle electrical system/DME control module

Possible causes of fault:- 'no display' Loads are/were switched off temporarily. The load management operation was enabled because of undervoltage.

Check and/or replace the battery - verify the charging system is working.

when the battery starts to go all sorts of strange things start happening, after market batteries are ok, the age is the problem

I have read that some people describe the vehicle electrical module (VES) can do bad and give this message. Do you know what this module is and a part number.

[Duram]

The part numbers are 955.618.027.00 for 2003-2004 models, and 955.618.027.01 for 2005-2006 models. The 2003-2004 version seem to be more common to have problems. In your case I don't think that you have a VES problem. Usually you get strange things happening, like certain lights or electronics not working. One common way to get the fault code you have is to have the vehicle on and not running, then use a diagnostic tool without a battery charger connected for more then about 10 minutes. The electronic loads of the control module reduces the battery power triggering this fault code. Normally if you were not using diagnostic tool the VES module will start to shut down the modules to reduce power consumption. But the diagnostic tool will keep the network awake and prevent the modules from shutting down. The 2003-2004 Cayennes use a K-Line communication to the Instrument cluster, then the instrument cluster converts the communication to a CAN-Bus message. The passing of these CAN messages keeps the vehicle in awake mode preventing the shut down. In the 2005+ Cayennes they are similar and use many of the same modules but the CAN bus is used directly and can have the same effects.

I have a durametric. Can I use this to determine if there is a problem with my VES on my 2004 cayenne turbo. Are there any specific tests for the VES in durametric or do you just look for weird electrical code errors.

I'm curious of your results if you recall from 12 yrs ago. haha.  I'm finally learning how to use my duramtric on my 04 CTT which I've owned for the past 10yrs now.  And I'm still enjoying the Ole pig. I have a new (last year 2023) Napa battery, their highest premium model, and am throwing the 907.
