Review on OHP OBD2 Scanner Adapter Splitter for Tesla Model 3 & Y (2019-2021): Boost Diagnostic Efficiency by Devon Dober

Revainrating 2 out of 5

Bad belt? Best in Tools and Hardware

Have connected this harness several times to my 2021 Tesla Model 3 LR. After installation and starting, the contacts of the main battery make a loud "click” about every 30-40 seconds, the car stalls and starts again. I've checked the connections etc three times but to no avail. I use it with OBD MX+. Maybe I have a bad wiring harness...?...because once I removed it and installed it at the factory, everything is fine! Can definitely not recommend for 2021 model 3 with heat pump.

Pros
  • Supported apps, free and paid (NB! None included with this product)
Cons
  • Hard to tell
