TROUBLE DIAGNOSES — Supplemental Restraint System (SRS) — Schematic
BF-7034wiring diagramUnverifiedDense single-page schematic — wire colours and exact pin numbers are not reliably legible at the scan resolution. Connectivity is recorded structurally; per-wire colours marked '??'. Pin labels on the diagnosis sensor unit are coarse functional names rather than verbatim pin numbers.

NOTE
Variant notes (right margin): "With dual air bag" and "With side air bag". Branches to the side inflators / satellite sensors / pre-tensioners are present only on equipped models. Drawing reference: YBF275; Air Bag Diagnosis Sensor Unit connectors visible on the right (M73 / M75 / M76 / M77 with 16- to 18-pin layouts).
