If you want, I can:
Use the Proteus Virtual Terminal or Digital Oscilloscope tool. Attach oscilloscope probes to the TXD pin (digital logic) and the CANH / CANL lines (differential logic) to observe if the microcontroller is actually pulsing data out.

PIC18F458 or PIC18F258 (both feature integrated hardware CAN controllers). If you want, I can: Use the Proteus

By default, older versions of Proteus (such as Proteus 7 or early builds of Proteus 8) may lack a dedicated, animated SPICE model or schematic symbol for the MCP2551. While the device footprint is always available in ARES for PCB layout, running an active VSM (Virtual System Modeling) simulation requires adding custom library files.
