Harley ECU Issues?
First, since ECU’s are rarely faulty we always check these concerns first before replacing a unit:
- Check the pins
- The connectors can get iffy as they are not made to be unplugged and re-plugged.
- Often caused when unplugging units to access batteries instead of moving ECU’s out of the way
- Crimping the individual ends can work but we suggest just replacing problem points.
- Check your grounds!
- Check your sensors!
- Wonky ECU responses can be caused when bad info is used to process data
- The connectors can get iffy as they are not made to be unplugged and re-plugged.
Yes, sorry, this is a very simplified overview of ECU issues. In our shop we have access to advanced diagnostic and electrical tools to aid identifying problems with ECU’s. For those of you who don’t have access to those recourses we hope that these tidbit can lead you down a happy trail of savings. 😎
