EFI Fault on CSC SG400

ssnlacher · 03-18-2023, 05:50 PM

Hi everyone. The EFI fault indicator light (check engine light) just turned on on my CSC SG400. I tried looking at the owners manual and the wiring diagrams provided by CSC, but these are honestly the most stereotypically Chinese part of the bike. They are complete crap. On the wiring diagram it says there is a diagnostic port on the ECU, which is just clear not there in real life. There are a few unfilled connectors on the bike that could be diagnostic ports. However, I’ve already tried using an OBDII scanner with a motorcycle port adapter on these ports which did not work. I was wondering if anyone has already dealt with this issue and could offer me some insight, I would greatly appreciate it so that I don’t have to go over the entire wiring diagram. Also, just for clarity, the bike seems to be running perfectly fine so I have no clues that point to what the issue is. Thanks in advance for any help.
