Measurement and decision sequence

1. Compare tire circumference/pressure, alignment, bearing play and wheel speeds under the same condition.
2. Scan shared U-code/timestamps across ABS/ESC, steering, SRS and ADAS modules.
3. Verify supply voltage, network health and exact ECU/variant identity before software/coding updates.

Misdiagnosis traps

• Mistaking mechanical alignment error for a sensor/ECU fault.
• Starting coding/calibration with low-voltage or network faults present.
