When a 2022 Volvo XC90 encounters a crash event, the airbag ECU deploys and forces the 48V hybrid battery into protection mode. Below is the step-by-step procedure to reset the crash data and unlock the battery using CGDI CG100X Programmer.

Step 1: Physical Inspection & Wiring

1. Inspect CG100X connector pins. Use a small screwdriver to loosen the hard rubber seal to avoid bending pins during cable insertion.
2. Connect CAN-H, CAN-L, 12V (+), and GND wires according to CG100X BCM menu wiring diagram.
3. Use the included bench adapter rather than direct pin solderless clips for a more stable connection.

Step 2: Power Supply Calibration (Crucial Troubleshooting)

• Issue:Connecting a 14V–15V power adapter causes the software to prompt “Please connect external power supply” even when powered.
• Fix:Swap to a steady 6V 2A power supply. Once connected, the blue power LED will stay solid, and the software will recognize the hardware.

Step 3: Crash Data Reading & Clearing

1. Open CG100X softwareand navigate to: BCM ➔ Volvo ➔ Select Metal Shell Battery Module.
2. Click Readto backup original eeprom/crash records.

3. Click Clear Faults. The software will execute the write routine automatically.

4. Verify the modified data (check hex addresses 10 and 20 to confirm crash codes have changed to 00/cleared status).

5. Reinstall the battery into the vehicle to verify crank initialization.
