As a mechanic who regularly works with different car makes and models, I needed a dependable OBD2 scanner for my side projects at home. After comparing several Innova scan tools, their features, and pricing, I chose the Innova 3040RS diagnostic code reader.

If you’re considering a budget-friendly OBD2 scanner, this Innova 3040rs review will help you decide whether this tool is the right fit for your home garage or small repair shop.

FAQs
Question: Does the Innova 3040e or 3040rs work on OBD1 vehicles?
Answer: No, it doesn’t. The Innova 3040e scan tool is only compatible with OBD 2-compliant vehicles manufactured from 1996 and newer. If the car is OBD 1 compliant, then it won’t be compatible with this device. This includes domestic, European, and Asian light trucks, cars, hybrid, or SUVs. If you want an OBD I code reader, you should look here.
Question: Does this scanner feature Bluetooth and Wi-Fi?
Answer: No, it doesn’t. If you want an Innova scanner with Bluetooth or Wi-Fi connectivity, you must acquire a more advanced scanner. For instance, the Innova 3160 scan tool or even the Innova 3140g scanner. Note that you will have to pay more to get high-quality diagnostic code readers.
