A technician struggles to diagnose an electrical fault on a Ford Escape involving LIN bus communication and wiper motor module, lacking a clear diagnostic workflow for modern vehicle networks.

Existing diagnostic tools do not provide clear guidance or step-by-step procedures for LIN bus-related electrical issues, relying on generic multimeter tests that may misinterpret modern vehicle signals.
