This vehicle has been struck by lightning. It starts and runs but doesn't run good. Miss fire on cylinder three because of a bad coil. I unplugged the coil but it didn't have any affect on my communication issues. There are lots of warning lights on on the dash. Mostly for the ADAS systems. The battery light and brake light are on as well. I can't communicate with any of the modules on the CAN high speed. I tested my voltage on pins 6 and 14 and they equal 5 volts. 3.2 on one and 1.8 on the other. I don't have much experience with communication issues so any help would be great. Thanks!

I'd contact Allstate or State farm - they might be able to help you with this one. This car would be a challenge for any veteran technician.......

My experience with lightning strike vehicles is that all modules will get hit with high voltage either a direct way, lightning actually hitting vehicle or indirect, EMP! When a module gets hit its dead! I’ve never had a module survive after a lightning strike! Other stories may differ!

Have you checked every single fuse? Do you have access to good wiring diagrams? Pick a module that is not communicating and test all powers, grounds and data lines. Run a CAN bypass from DLC to your module that is not communicating and see if it starts communicating. Let me know your result. Pick a module that is the easiest to access, that is not communicating. Let me know.

I had an experience with a 2014 Toyota RAV4, hit by a lightning, I end up replacing almost every module in the vehicle. The only good thing with this vehicle is that you can used used modules from a donor vehicle, now for ADAS you may have to buy new Radar unit. Did you see where the lightning came through? The one I did came through the antenna of the vehicle, and I hade to change the…

I have encountered many vehicles struck by lightning. Sometimes it is one or two modules that get damaged and sometimes it is 8-10. When it happens, it takes down the entire CAN network (usually because it shorts CANH with CANL inside of the modules. The owner's insurance normally will cover as it is an accident. If you want to try to figure out which module(s) is taking down the system, unplug…

A quick update. I have replaced the abs module and have determined that the meter, pcm, and power steering module need replace yet. I’ll let you know the outcome after those are installed. Thanks

I replaced these three modules and the alternator and the vehicle is working and back on the road! Sorry the job took so long to complete.
