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.

Reserved. If this appears, treat it as manufacturer-specific.
