SRS (Supplemental Restraint System) codes require specialized diagnostic tools. Standard OBD2 scanners typically can't access these safety-related codes. For accurate airbag system diagnosis, invest in a professional scanner with full-system capabilities or seek expert assistance.

TPMS (Tire Pressure Monitoring System) alerts you when your tires are too low on air. Cars have either sensors inside the tires or use the ABS system to detect problems. When your TPMS works right, you drive safer, use less gas, and your tires last longer. Check it regularly to stay safe on the road.
