CAN-High and CAN-Low should be mirror images of each other. If the "recessive" voltage isn't exactly 2.5V, or if the "dominant" levels are slanted, you are looking at a physical wiring fault or a terminating resistor failure. 5. Documenting Your Findings (The PDF Advantage)
The days of guessing with a scan tool are over. The automotive oscilloscope is the only tool that shows you what is actually happening in the circuit. However, without a reference, a waveform is just a squiggly line. That is why building, using, and sharing libraries is the single fastest way to increase your diagnostic accuracy.
Proper setup is the foundation of accurate waveform analysis.
