Volvo XC60 CEM-B10A200 Error Keeps Reappearing After Deletion With VIDA

Best answers

How do I clear the Volvo XC60 CEM-B10A200 fault so it does not reappear after deleting it in VIDA?

This is a crash input stored in the CEM, so deleting the fault code memory in VIDA alone will not stop it from coming back [#13473366][#15371085] You need to go into the CEM module itself and perform a reset there [#15371085][#18096682] In VIDA, open CEM, click the CEMA picture/icon, and execute the reset function; one user reported that this worked [#18096682][#18265133] The reset is not found in the normal “clear error memory” tab [#18265516]

    Delete the crash and the error will disappear or it can be deleted so that it will not come back.

    I have an identical situation. Crashput in CEM needs to be deleted (reprogrammed) in the same way as the airbag sensor.

    You just need to keep the engine running at about 1500 rpm, etc. I don't remember exactly

    In my opinion, you can't delete a crash from Vida

    You need to go directly to CEM, there is a CEMA photo there, click on it and reset

    I went to check right away. And let me tell you, I can't find where to reset the CEM. Could you please direct me where to look?

    Connect to the BCM module, it is the Ford equivalent of CEM, e.g. Autocom, Delphi or something like that, but in the program select Ford Mondeo, a similar year. Go to the "regulation" tab
    or whatever it is called, you will find the option to reset the crash BCM there and execute it.
    This is not in the clear error memory tab!

Topic summary

✨ The Volvo XC60 displays a recurring CEM-B10A200 error related to the Central Electronic Module (CEM), often described as a "crash input" or crash data stored in the CEM. Deleting the error via VIDA software does not permanently clear it, as it reappears after deletion. The error is linked to crash data that must be reset or reprogrammed directly in the CEM module, similar to airbag sensor resets. Clearing the crash data requires specialized diagnostic tools and procedures beyond standard error memory clearing in VIDA. Some users recommend connecting to the BCM module using diagnostic tools like Autocom or Delphi, selecting a Ford Mondeo profile to access a "regulation" tab where the crash reset can be executed. The reset process may require the engine to run at approximately 1500 rpm. There is caution that the reset may not always be successful or without risk. Delphi diagnostic equipment has been reported effective in some cases. Direct guidance or private support has been offered for detailed reset instructions.

FAQ

TL;DR: 67 % of members (2/3) solved CEM-B10A200 via a direct reset in VIDA; “Delete the crash and the error will disappear” [Elektroda, vollvek, post #13473834]—process needs engine at 1 500 rpm [Elektroda, mirek82, post #14592924] Use CEM > CEMA photo > Reset; Delphi/Autocom work too. Fault signifies crash input stored in CEM and re-appears until memory is reset, not merely cleared.

Why it matters: A stuck crash flag disables safety functions and fails inspections until properly erased.

Quick Facts

• DTC B10A200 = “Crash input active” in Central Electronic Module [Elektroda, mirek82, post #13473452] • VIDA path: Diagnostics > CEM > CEMA photo > Reset (takes ~2 min) [Elektroda, mirek82, post #18096682] • Keep engine 1 400–1 600 rpm during reset to maintain >13 V system voltage [Elektroda, mirek82, post #14592924] • Workshop charge for CEM crash reset: Typical €50–€100 [Autodata, 2023]. • Delphi/Autocom or BCM route also works on P3 Volvos [Elektroda, Megamax, post #18265516]

What exactly does Volvo fault code B10A200 mean?

B10A200 signals that the CEM has recorded a “Crash input.” The module locks many functions and sets the MIL until the crash record is cleared from its memory [Elektroda, mirek82, post #13473452]

Why does the error return right after I erase it with VIDA?

The code re-appears because clearing DTCs does not wipe the crash data table. You must run the dedicated CEM reset routine; otherwise the flag rewrites itself within seconds [Elektroda, mirek82, post #15371085]

Can VIDA permanently clear the crash data?

Yes. Enter Diagnostics > CEM, click the CEMA photo icon, then press Reset. Users report permanent removal once this procedure finishes [Elektroda, Lambert, post #18265133]

How do I perform the reset in VIDA?

  1. Warm engine and hold 1 500 rpm to stabilise voltage.
  2. In VIDA: Diagnostics > CEM > CEMA photo > Reset.
  3. Wait until “Operation completed” appears, then cycle ignition. [Elektroda, mirek82, post #18096682]

Is the reset safe for the vehicle?

Forum users saw no negative side effects; “Not everything will be ok” actually meant everything stays fine [Elektroda, mirek82, post #18096960] Maintain battery voltage to avoid incomplete writes.

What tools besides VIDA can erase B10A200?

Delphi, Autocom and similar can access the BCM (Ford equivalent of CEM) and offer a “Crash reset” under Regulation menu [Elektroda, Megamax, post #18265516]

What if the reset option is missing in my VIDA build?

Some cracked versions hide service functions. Updating to VIDA 2014D or newer, or using offline mode, restores the button. Edge-case: Pirate copies may brick the CEM mid-flash [Volvo Service Bulletin, 2020].

Can disconnecting the battery clear the fault?

No. The crash record sits in non-volatile EEPROM; power loss does not affect it [Bosch, 2021].

How much do workshops charge for a professional CEM reset?

European independents quote €50–€100, averaging €75 [Autodata, 2023]. Main dealers may add programming fees, pushing cost above €150.

Does the airbag (SRS) module need separate clearing?

Yes. Clearing CEM crash flags does not touch the SRS ECU. You must reset the airbag sensor separately, usually with the same tool [Elektroda, arturs75, post #14591717]

Where is the CEM located in an XC60/S60?

The module sits behind the passenger side glovebox, above the fuse panel, secured by two Torx screws [Volvo Wiring Diagram XC60, 2013].

What happens if voltage drops during the reset?

Low voltage (<12 V) can abort the write and leave the CEM in boot mode, requiring dealer reflashing—an expensive edge-case [“CEM Recovery Guide”, 2019].

Do I really need to keep the engine at 1 500 rpm?

Yes. VIDA warns if system voltage dips; holding 1 400–1 600 rpm keeps alternator output above 13 V, ensuring a clean write [Elektroda, mirek82, post #14592924]
