Multi-axis Acceleration Sensor Module B Missing Calibration

Where it lives

For C0522, start at the sensor the description names.

Check these first

• A calibration that was never performed after service
• A module replaced without programming
• A voltage loss that cleared the learned calibration
• A fault in multi-axis acceleration sensor module B
• A scan tool procedure that did not complete

What to do next

1. Check for low battery voltage or a recent module swap
2. Run the acceleration sensor calibration procedure
3. Confirm the calibration completed on the scan tool
4. Replace the module if it will not calibrate
5. Clear the code and retest
