Bench test report says communication passed but the fault remains

Communication testing does not automatically reproduce every function under vehicle conditions. Ask which checks were performed and what the limits were. Give the installing garage the report alongside the original symptom and vehicle-side findings.

What to tell us

  • Bench scope.
  • Original symptom.
  • Installed-system evidence.

Before arranging work

A bench result has a defined scope. Ask which functions and conditions were assessed, and keep it with the vehicle-side findings. Before dispatch, confirm the workshop accepts the specific unit and understands the original complaint.

Ask AXION about this fault. Send the vehicle details and the information above. Please agree an appointment or postal assessment with us before travelling or sending a module.
