An owner may report that the fuel pump cannot be heard. That observation is worth keeping, but it is not a complete electrical test. With P0230, the repair enquiry should explain what the vehicle does when starting is requested and what the diagnostic report actually says.
Start with the circuit designation
HELLA’s reference identifies P0230 with the fuel pump’s primary electrical circuit. Read the code reference. The vehicle wiring diagram is then needed to establish how that circuit is controlled on the particular model.
Do not assume that a relay, pump controller and engine ECU are interchangeable descriptions for one component. Record the exact unit identified by the technician.
Build the starting timeline
- Does the engine crank normally, start briefly or never fire?
- Did the problem begin after running out of fuel or after electrical work?
- Have a relay, pump, controller or fuse already been replaced?
- Is the fault constant, or does the vehicle sometimes start normally?
For garages, attach the relevant command, supply and circuit findings with their test conditions. Distinguish an observed fuel-pressure result from an electrical-control result. Both may be useful, but they answer different questions.
Keep testing controlled
Do not bypass a relay or apply power to unidentified terminals as an owner-level experiment. Fuel-system work brings both electrical and fire risks. Keep the original scan and parts history before another repair attempt.
Ask AXION about the electrical fault. We can discuss the evidence needed before a module is sent or the vehicle is booked for assessment.
Use the full fault description from your scan and the repair information for your vehicle.
