g37 2010 viper 5904 and db all weird

Thanks for the suggestion. From DEI's explanation, I shouldn't have to touch the PTS button at all. I read about your suggestion in the manual for the older firmware, which requires the additional starter relay to be wired up to the IPDM. I'll give it a shot tomorrow morning when I head to work. What I can say is that I discovered another way to restart the vehicle when the remote starter disables, which is to press the start button once (which stops the engine), then press the brake pedal immediately after pressing the button and it restarts itself. Obviously still not the ideal solution but a step closer. I figure this means that a double press of the button will probably only get me to the ACC position so it might even take a triple press to get it back to the ON position and hopefully in that process, the BCM won't attempt to stop the engine. I'll see if the PTS illumination does flash upon entry like the older firmware manual suggests (from memory, I don't believe it does) and try a double and a triple press.

Nope. Didn't work. The NISSHT03 firmware acts nothing like the NISS02 firmware. There's no flashing PTS button upon entry, pressing the button once, twice or three times in rapid succession still kills the engine but again, if I immediately press the footbrake after doing so, the vehicle will start again and remain started. It's as though the unit attempts to reissue the start command to the vehicle in an effort to keep it started which may work for the USDM vehicles but that clearly doesn't work for the JDM BCM vehicles. I'm going to have to whip out the CAN bus packet analyser and log what actually happens so I can design my own interface to fix this.
