B03xx
Body electronics
Cabin and body electronics: climate control, seats, lighting, locking, mirrors, and restraint and airbag systems. This dataset cannot narrow a body code further - the groupings behind the third character are not standardised across makes, and no free source covers them.
No open-source descriptions exist for this system, so its codes are read from their structure.
Standardised (SAE/ISO). Standardised meaning, consistent across manufacturers.

Read this code from your own car
Plug an ELM327 adapter into the OBD-II port under the dashboard. Pin16 reads every stored, pending and permanent code, explains each one like this page does — offline, with no account — and shows what the car recorded when the fault was set.
