2019 Ford Fusion Hybrid (Not a Plug-In)

[JEE7600]

2019 Ford Fusion Hybrid 70k Miles

The codes I got were

 

P0562 System Voltage Low
P0689 ECM PCM Power Relay Sense Circuit Low
U0103 Lost Communication with GSM Battery Energy Control Module
U3001 - Control Module Improper Shutdown
U3003 - Battery Voltage
U0401 - Invalid Data Received from ECM PCM Secondary OBD Control Module C
P0887 - TCM Power Relay Control Circuit High
P1A10 - Hybrid Power train Control Module - Battery Disabled
U0104 - Lost Communication with Cruise Control Module
U0298 - Lost Communication with DCDC A
U0412 - Invalid Data Received from BECM A

I replaced a 12V Battery and still get a service battery charging issue. I can still drive around but when I connect a jump box to the 12V battery you can see it runs between 12.4-11.6. I assume its the DC to DC Inverter? If I replace it does the new one need to be reprogrammed?

With many codes like that it's really hard to tell what the cause is.  They tend to cascade like that.  The "P1A10 - Hybrid Power train Control Module - Battery Disabled" stands out to me as it sounds like it has cut off the HVB all together, which means the DC-DC isn't getting any input.  With the car on and the HVB working, you should get 14V+ at the battery from the DC-DC.  When driving around is the ICE always on or does it still shut off and go into EV mode briefly? 

 

Good thing you are still under hybrid warranty.  If it is the BECM that's expensive.  Good luck.
