Volvo 48V Battery Crash Data Removal – Symptoms, Fault Codes

Volvo 48V Battery Crash Data Removal – Symptoms, Fault Codes & Repair Service

Many modern Volvo models equipped with the 48V mild-hybrid system store crash data inside the Battery Management Control Module after an impact or voltage event. When this crash data is locked, the 48V system may shut down, disable hybrid functions, or show persistent warning messages.

At The Vehicle Check, we specialise in Volvo 48V battery crash data removal, module repair, and fault code deletion when standard diagnostics cannot clear the issue.

What Is Volvo 48V Battery Crash Data?

Volvo’s 48V mild-hybrid system includes a 48V battery, DC-DC converter, Integrated Starter Generator (ISG), and a Battery Energy Control Module.
When a crash is detected—or even if voltage spikes occur—the system logs locked crash data.

This leads to hybrid system shutdown and ongoing electrical problems until the data is removed professionally.

Symptoms of Volvo 48V Crash Data

If crash data is stored, you may experience:

  • 48V system or hybrid system malfunction warning

  • Start/Stop not working

  • Reduced hybrid assist

  • SRS/Airbag warning light on

  • Battery not charging correctly

  • Vehicle going into restricted performance mode

  • Intermittent or no start condition

These issues persist even after repairs until the crash data is cleared properly.

Common Volvo 48V Crash-Related Fault Codes

Crash data may trigger Volvo-specific trouble codes, including:

  • U140A00 – Crash event stored in module

  • U3000-49 – Control module fault after crash

  • P0A0A00 – High voltage interlock

  • B11CF – 48V battery control module locked

  • P0AA0 – Battery energy module disabled

  • U019F – Lost communication with 48V energy module

  • P305300 – 48V system shutdown after crash

These codes usually cannot be cleared with standard tools.

  • Volvo XC60 B4 / B5 / B6

  • Volvo XC90 B5 / B6

  • Volvo S60 / S90 mild-hybrid
