Bluetooth OBD adapters

Bluetooth adapters can be a great compromise in getting professional functionality for less amount of money than with pro scan tools!

This lesson is from my premium OBD-II course provided for free to my email followers:

There are two types of Bluetooth adapters: the simple ELM327 and the more advanced J2534.

Using with Your Smartphone:
You can use these adapters with your smartphone, but make sure it’s compatible with your system. Some work only with Android or iOS.

ELM327:

• Cost: Cheap
• Functionality: Offers more than a basic code reader. You can use it with hundreds of different OBD-II apps.
• Capabilities: In addition to standard code reading, you can scan other control modules, see multiple live data graphs at once, and cast live data on your dashboard radio.
• Limitation: Slower for quick engine checks compared to a dedicated code reader, which is important when you need to work fast, like checking a used vehicle before buying.

J2534:

• Cost: More expensive than ELM327
• Functionality: Advanced features similar to expensive scan tools.
• Capabilities: Bi-directional testing, accessing all control modules, unlocking hidden vehicle features.
• Limitation: Requires a yearly subscription for advanced features, which can become costly over time.

Cost Consideration:
While the ELM327 and J2534 adapters are affordable, using advanced features often requires a yearly subscription, making them expensive in the long run.
