Title: Volvo XC40 2025 – BCM2 C006154 / C006254 – Acceleration Sensor Calibration Failed

Hello everyone,

I am trying to resolve two fault codes on a 2025 Volvo XC40 B3 Mild Hybrid using VDASH 2.0 and a DiCE interface.

The BCM2 module reports the following DTCs:

• BCM2-C006154 – Lateral Acceleration Sensor – System Programming Failures – Missing Calibration.
• BCM2-C006254 – Longitudinal Acceleration Sensor – System Programming Failures – Missing Calibration.

To perform the calibration, I accessed the Advanced menu in VDASH and selected "Calibrate acceleration sensors" under the Supplementary Restraint System (SRS).

However, when executing the command, VDASH returns the following errors:

• IMMO: FAILED [0x13]
• NEGATIVE [31] – ROOR – Request out of range
• The command resulted in error.

VDASH also displays a warning that the VGM / firewall security key has not been found, and the software is operating in limited mode.

Could someone please confirm whether I am following the correct procedure to calibrate these sensors?

Is the calibration supposed to be performed through the SRS module, or is there another procedure specifically for the BCM2?

Could the missing VGM security key be responsible for the calibration failure?

I have attached screenshots showing the DTCs, the calibration menu and the error message.

Thank you in advance for your help.

Best regards,
Antonio
