Battery Module Crash Data Reset & BMS Repair
Specialist battery BMS crash data reset, battery-module unlock, diagnostics and programming for supported 12V, 16V and 48V vehicle battery control modules. Workshop service is available near Birmingham, with selected national mobile support, UK & Ireland by-post service and approved international enquiries.
Battery management electronics
Reset crash data, battery lock events and supported BMS faults.
Modern mild-hybrid, hybrid and electronically managed battery systems can store crash-event, shutdown or lock data inside the Battery Management System. A module may remain locked even after mechanical repairs are complete, and some faults cannot be cleared with normal vehicle diagnostics alone.
SG-Tronic Motorsport provides BMS crash reset, 48V battery reset, supported module repair/programming and bench verification. Each unit is identified from its exact part number, controller family and stored fault information before work begins.

Crash-data reset, unlock, diagnostics and programming.
Service availability depends on the battery module, processor, fault state and physical condition. We confirm compatibility before accepting the unit.
48V Battery Reset & Unlock
Assessment and reset of compatible 48V mild-hybrid battery modules that remain locked, inactive or unable to re-enable after a fault event.
BMS Diagnostics
Part-number identification, communication checks, fault-code review and bench assessment before reset, repair or programming.
BMS Programming & Coding
Supported software, configuration and programming procedures for compatible Battery Management System modules.
Battery Module Data Repair
Assessment of supported EEPROM / flash data where crash flags, internal errors or corrupted control data prevent normal operation.
Bench Verification
Communication and data checks after reset or programming, with the module verified before return where the platform supports testing.
Common symptoms
When a battery BMS crash-data service may be required.
Crash or collision lock
Battery module remains disabled after accident repairs or safety-system activation.
Battery will not wake or charge
Module communicates incorrectly, stays inactive or prevents controlled charging.
12V / 16V / 48V warning
Battery or hybrid-system warning remains active after conventional fault clearing.
No-start / limited operation
Vehicle may not start, may enter reduced-power mode or may disable mild-hybrid functions.
Persistent BMS DTCs
Stored internal, crash-event, actuator-lock or energy-management faults return immediately.
Replacement battery-module issue
A replacement or repaired module requires supported reset, programming, coding or verification.
Supported battery-module references
Supported BMS reset modules and part numbers.
The references below are listed in the supported battery-reset service platform. Reset availability still depends on the exact hardware/software version, stored fault state and physical condition of the module, so send a clear label photo and fault codes before booking.

Frequently asked questions
What is a battery BMS crash data reset?
Some vehicle battery management modules store a collision or safety-event flag that can keep the battery system locked after repairs. On supported modules, the stored event can be assessed and reset using specialist bench or data-access procedures.
Do you reset Mercedes 48V battery modules?
Yes, selected Mercedes-Benz 48V BMS modules using TC27XX-64F and 95M01 memory are supported. Send the exact part number and fault codes first so compatibility can be confirmed.
Can I post my BMS module from Scotland, Wales or Ireland?
Yes. Approved removed modules can be sent by post from across the UK and Ireland after a compatibility check. International postal enquiries are also accepted for supported modules.
Do you offer mobile battery BMS service?
Selected diagnostic, identification and supported reset work can be arranged as a national mobile service depending on the vehicle, module and location. Bench-only procedures may still require the unit to be removed.
Can you reset Tesla, Porsche or Volvo battery modules?
Selected Tesla 16V, Porsche 12V and Volvo BCSM/MVBM battery module references are supported by the service platform. Exact support is confirmed from the part number before work is booked.
What information should I send before booking?
Send the vehicle make/model/year, fault codes, symptoms and clear photographs of the battery-module label showing the full part number and voltage.
