How to Unlock Volvo 48V Lithium Battery with CG100X?

Tutorial: how to unlock and repair Volvo S90/ V90/ XC60/ V60/ XC40/ S60/ XC90 48V hybrid lithium battery using CG100X programmer in bench CAN mode.

Model example: 2022 Volvo XC90

A 2022 Volvo XC90 involved in a front-end accident triggered the vehicle’s safety systems. When airbags deploy, the hybrid battery enters a protection mode, preventing the vehicle from starting. Even after physical repairs, the battery requires a software unlock to restore functionality.

Connection Setup: The programmer connects to the battery via a simple wiring configuration with positive, ground, CAN high, and CAN low connections.

Power Requirements: An important technical consideration emerged during testing. The CG100X requires precisely 12V power (2A recommended). When the technician attempted to use a 14.5-15V power supply, the programmer failed to recognize the connection. Switching to a proper 12.6V 2A charger resolved the issue.
