Hello everyone,

I have a fit 2014 GK3 with Automatic transmission and having an issue where the engine shut off after driving a few km and could reproduce the error if I maintain the acceleration at 3000 rpm for few minutes and the following error has been detected when scanned.
U0100-00 --> FCAN Malfunction (EPS / TCM)
U0416-68 --> VAS SYSTEM Failure
U0122-00 --> F-CAN Malfunction (EPS Control Unit PCM/TCM)
86-13 --> F-CAN Communication with PCM (gear system)
86-12 --> F-CAN Communication with PCM (Engine) Malfunction 83-12 PCM (gear system) failure

The mechanics is doing his best to locate the problem but unfortunately he can't figure out exactly what causing it and really need help on this. Note things that has just been replaced are:
- Battery
- Spark plug with that of Honda itself
- Transmission fluid

Anyone reply is most welcome as it could help in the troubleshooting.

Thanks,
