    Battery Change Touble Codes

    2017 GP1800

    So after installing a new battery I'm now getting a check engine light. this key is in perfect condition and just has the basic mods (ECU, intake, ect.)
    I'm getting a flashing red light with the engine symbol and using my Riva maptuner x I see the following codes.

    Curious to know if anyone has experience to this issue. Any help would be greatly appreciated.

    I think you get those codes from having the harness unplugged from the ecu for the maptuner

    You likely have this info already... as per YDS docs :
    124-128 TPS
    131-135 ETV
    15_ ?? might be RiDE codes

    FWIW, I've got a battery disconnect switch mod on my 2012 VXR that I flip Off when garaged between weekends. Hence, one could say I'm "battery changing" all the time, yet never once has the ECU ever threw a code. Can't see why a newer GP would. Why the batt change-out? Were you having voltage issues? Perhaps a short somewhere or bad ground is causing erratic voltages thus thus components are not passing the ECU self-checks?? Spit-balling here.
