Frequently Asked Questions Q: What vehicles are compatible with the V315 OBD2 scanner? A: The V315 OBD2 scanner is compatible with most petrol and diesel vehicles sold in the US, EU, and other markets that are equipped with a standard OBD-II port — generally all cars manufactured after 1996. It supports all five OBD-II protocols: CAN, KWP2000, ISO9141, J1850 PWM, and J1850 VPW. Q: Do I need a battery or charger to use this OBD2 code reader? A: No. The V315 scanner is powered entirely through your vehicle's OBD-II diagnostic port — simply plug it in and it powers on automatically. No batteries or external chargers are required. Q: Can the V315 turn off my check engine light? A: Yes. Once you have identified and addressed the issue causing the fault code, the V315 allows you to clear the Diagnostic Trouble Code (DTC), which will turn off the check engine light on your dashboard. Q: What is the I/M Readiness Test feature? A: The I/M (Inspection/Maintenance) Readiness Test checks whether your vehicle's onboard monitoring systems have completed their self-tests and are ready for an official emissions inspection or smog check. This helps you avoid failing an emissions test due to incomplete system monitors. {"@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{"@type": "Question", "name": "What vehicles are compatible with the V315 OBD2 scanner?", "acceptedAnswer": {"@type": "Answer", "text": "The V315 OBD2 scanner is compatible with most petrol and diesel vehicles sold in the US, EU, and other markets that are equipped with a standard OBD-II port — generally all cars manufactured after 1996.
