Review: Absolute genius! - As part of my job - I need to access the CAN signals from the OBDII connector. I have lots of specific cables from various vendors blah blah blah. Nuff said. For this custom application - I needed complete access to every signal on this test vehicle's OBDII connector - and this brilliant box - provided such. Flashing LED lights on the activity pins. I am in love with this box - since it saved my... This is absolute genius. And happy to discover it is from a company founded in my state - Minnesota - who knew? I ordered the box on Friday. Paid $9 bucks for Saturday delivery. Excellent testing today Sunday. Now off to Detroit area Monday for my meetings with customers. BTW - The box accepts industry standard "banana plug" leads. I bought off-the-shelf leads at my local RS electronic supplier to fabricate some custom cables to my "black box" - and they fit the breakout box as expected. Review: Works perfect - Does as it should. Good connections. Add scan tool to the output. ## Features - Used for diagnosing electrical faults and CAN bus line activity - Check power and ground circuits, check active protocol lines, or connect a multimeter or oscilloscope for detailed signal analysis - Connect, detect, monitor voltage and more - Connects between Diagnostic Link Connector (DLC) and scan tool - Detects data and protocol communication and monitors system voltage with a display and high/low alarm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00A6AS3XU | | Best Sellers Rank | #762,087 in Automotive ( See Top 100 in Automotive ) #2,194 in Code Readers & Scan Tools | | Brand | OTC | | Brand Name | OTC | | Color | Black, Blue, Gray, yellow | | Compatible Devices | Scan Tool, Multimeter, Oscilloscope | | Customer Reviews | 4.7 out of 5 stars 181 Reviews | | Global Trade Identification Number | 00731413571701 | | Included Components | Item | | Item Dimensions | 9.6 x 4.9 x 3 inches | | Item Weight | 1 Grams | | Item dimensions L x W x H | 9.6 x 4.9 x 3 inches | | Manufacturer | OTC | | Measurement Type | Multimeter | | Model | 3415 | | Part Number | 3415 | | Power Source | Corded Electric | | Style | Digital | | Style Name | Digital | | UPC | 731413571701 | | Unit Count | 1.0 Count | | Warranty Description | One year limited warranty | ## Product Details - **Brand:** OTC - **Power Source:** Corded Electric - **Style:** Digital - **Color:** Black - **Item Weight:** 1 Grams ## Images ![OTC 3415 CAN Test Box - Use to Diagnose Electrical Faults and CAN Bus Line Activity, Check Power/Ground Circuits and Active Protocol Lines, and More - Image 1](https://m.media-amazon.com/images/I/71JYk3S-bYL.jpg) ![OTC 3415 CAN Test Box - Use to Diagnose Electrical Faults and CAN Bus Line Activity, Check Power/Ground Circuits and Active Protocol Lines, and More - Image 2](https://m.media-amazon.com/images/I/71KP+j3ulCL.jpg) ![OTC 3415 CAN Test Box - Use to Diagnose Electrical Faults and CAN Bus Line Activity, Check Power/Ground Circuits and Active Protocol Lines, and More - Image 3](https://m.media-amazon.com/images/I/81fULzgNYhL.jpg) ## Questions & Answers **Q: How does this detect what protocol is being used on the can bus? all i see is a volt meter built into a simple breakout box?** A: You have to use a lab scope to see anything regarding can bus. Here is a video from snap on tools thhttps://www.youtube.com/watch?v=DhX11X5ihws at may help you. If your using a volt meter all you will see is average voltage. **Q: Dear friends, what are the main differences between this model and model obdii protocol detector & break out box diagnosed obd obd2 connector | warran** A: Just looked at the obdII protocol detector & breakout box. Looks like the two are basically the same thing. I would say the otc piece is probably a little better quality piece, of course it costs a little more money. But the two will function pretty much the same way. **Q: hi,can you shipping for australia? or not?** A: Sorry, we only ship to USA Based addresses. **Q: Does it come with Jumper wire in the kit?** A: yes it comes with two jumper wires, one is a switched normaly open wire and the other wire is a solid wire. both jumpers have 4mm unshrouded male banana jack adaptors. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Absolute genius! *by E***Y on May 5, 2014* As part of my job - I need to access the CAN signals from the OBDII connector.

Good connections. Add scan tool to the output. ### ⭐⭐⭐⭐⭐ Excellent product *by M***D on June 27, 2020* The only feature this is missing is the ability to isolate pin 16 from the vehicle in case you need to pipe 12v in by yourself. Aside from that, it's a great breakout box. Connections are nice and snug and the pass through ability for your VCI is excellent. If you call yourself a diagnostic guy, you better have one of these. ## Frequently Bought Together - OTC (3415) CAN Test Box - Breakout Box and Protocol Detector Black - SG Tool Aid 23500 Back Probe Kit --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/12952847-otc-3415-can-test-box-use-to-diagnose-electrical-faults](https://www.desertcart.sn/products/12952847-otc-3415-can-test-box-use-to-diagnose-electrical-faults) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
