Code trouble

[Blueberry_st]

My accessport is reading a U1007 code but all it’s saying is no description available does anyone have any idea what it may be did a little research and it’s saying body control module but I don’t see how that can be right if I’m not having any problems with my car

If you clear the code does it come back immediately?

Here's what that code means:
OBD-II trouble code U1007 indicates a "Lost Communication with Battery Monitoring Sensor (BMS)". The car’s main computer cannot read the sensor measuring battery voltage, current, and temperature, which disables auto start/stop and causes the alternator to run in a fixed, less efficient default charging mode.
Top fixes to check yourself:

• Corroded Terminals: Inspect the sensor attached to your battery (usually the negative terminal). Corrosion at the terminals can disrupt the signal.
• Blown Fuses: Locate the small inline fuse or wiring harness connected directly to the battery's terminal. A blown fuse or damaged wire is a very common cause of U1007.
• Sensor Replacement: If the wiring and fuses are intact, the sensor module itself may need to be replaced.

Note that once you fix the cause of the U1007 code you have to reset the Battery Monitoring Sensor or the code will come back within 50 miles.
