Body: airbags, comfort and cabin systems.
Generic SAE-standard code: same meaning on every make.
Specific fault index within the subsystem.
DC/AC Converter A High Voltage Power Outlet “B” Circuit/Open. The control module detected an interruption (open circuit) in the DC/AC Converter A High Voltage Power Outlet “B” circuit, so the expected electrical continuity was not present.
B0128 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether B0128 is removable in your case.
