Explain this, I am not sure what it means
I had a check engine light with a U1000 CAN communication trouble code stored. There is a Nissan TSB regarding CEL "on" w/ U1000 and/or U1010 CAN comm codes stored in the memory, along with specific freeze frame data outlined in the bulletin. This bulletin covers various mid-2000's Nissan models. The fix is to clean a number of harness ground points where there is a ground eyelet attached to the chassis with a bolt. Some are in the engine compartment and some are in the passenger compartment, behind the dash or kick panels. The TSB shows where these points are for the given models and instructs to clean those ground points. Most of the grounds are fairly easy to access, but some are very difficult without pulling the dashboard.
