Failed High Voltage Battery

[Anti_Climax]

What's the actual fault code it posts? SOBDM is the module name for the charger.

There's not much between the port and the charger, depending on the actual fault you might be able to fix the existing part.

They didn't give me any other fault code. If that is the part number, it seems to confirm to me that the local dealer here in Atlanta doesn't really know what they are doing. I've ordered a FORscan device so I can, hopefully, read the fault codes myself. It should arrive on Friday. I will let you know the code once I get the Forscan.

Until you get the interface and Forscan, you can use Engineering test mode to read some fault codes.

So I was finally able to read the fault codes. I didn't get any of this info from the local dealer, which again suggests that they don't know how to deal with these cars. Here is the info from Forscan. I already tried resetting the SOBDM. That didn't work. Any other suggestions?



Code: U3000 - Control Module

Additional Fault Symptom:

-MAIN_BCCM_VOLT: 12.00 V - Main ECU voltage supply
-EXTERIOR_TEMP: 20 °C - Outside temperature
-SOBDM_BECM_PSR: PSR On - SOBDM to BECM Wakeup Status
-PCM_SOBDM_PSR: PSR On - PCM to SOBDM Wakeup Status

In the service manual, it says this for that code:

"U3000:04 Control Module: System Internal Failure INSTALL a new SOBDM .
REFER to: Secondary On-Board Diagnostic Control Module A (SOBDM) (414-03B High Voltage Battery Charging System, Removal and Installation)."

But it also says this:

"U3000:41 Control Module: General Checksum Failure CLEAR the DTC . REPEAT the self-test. If the DTC is still present, INSTALL a new GFM .
REFER to: Generic Function Module (GFM) (414-03B High Voltage Battery Charging System, Removal and Installation)."

So the SOBDM is the charger, the GFM is the module that deals with the lights and logic on the charge port.

You could use Forscan to reset and selftest the modules. I would think the GFM to be a much cheaper replacement part than the SOBDM. It could be a bad connection, or it might be a blown fuse inside of the SOBDM.

@bamaev, pm me and I can try to help you run your diagnostics.

[BamaEV]

@anti_climax, I tried to PM, but the messages seem stuck in my outbox.

So I got the full diagnostic code. It seems like I might need a new SOBDM. If I understand correctly, replacing the SOBDM requires discharging and recharging the liquid cooling system, so probably not something I can DIY.


Here is the Forscan info:

After 9 yrs 9 months and 92,000 miles my 2013 Ford Focus Electric has been diagnosed with a failed high voltage battery by the local Ford dealer. He wants $23,000 to replace it. Kelly Blue Book says it was only worth ~$3,000 if it was in good shape. I guess I have to say goodbye.

I joined this forum in 2013 when I was new to EVs and was concerned about battery life and range. The forum was helpful for reassurance.

At the time of purchase, I thought "Well if I get 8 to 10 years on the battery, it will have been a good investment." Now that it has been labeled DOA at the dealer, I'm still sad. It has been a very good car with almost no maintenance. I calculate it cost me $7.96 a day to drive.

My only complaint was the three "system failure; stop now" signals. In the past it has always been the 12V battery. This time changing the 12V didn't fix it. Fortunately this time was in the garage instead of in traffic where it definitely stops on its own.

It is still in beautiful shape with good tires and a brand new 12V battery. Seems like it would have useful parts for any 2013 Focus. I'm going to ask around but will probably try to donate it to charity.

May it rest in peace.

There are a few folks dealing with battery issues right now. Depending on what gets bought, it may be possible to get more than one vehicle fixed - but folks will need to coordinate.
