hello, can you please tell me what model of HITACHI OBDII SCANNER you are working with?...this is my story...we are having problems working on a NISSAN with a K25 engine. it arrived not starting showing a P03 code. i was told this was an ECM issue with communication. we replaced the ECM and the truck started and seemed to run fine. the code did not how up anymore. it then started to have issues with the fuel system. after troubleshooting that we replaced LP gas converter diaphragms and filter. all seemed to work fine. however, once we delivered the forklift to the customer a day later the code E23 appeared again. the forklift starts and runs but does not have acceleration. do you have any ideas?

thanks,
Jay
