Communication checks

DIF CAN Communication

Checks the communication of the Front Drive Inverter (DIF) Electronic Control Unit (ECU). Communication is established through Unified Diagnostics Services (UDS) over the Controller Area Network (CAN). When communication is established, the test will succeed. If the test fails, inspect the wiring and confirm the ECU is powered.
