2017 Subaru Legacy repair manual

2017 Subaru Legacy workshop manual (BN/BS): factory repair procedures and wiring diagrams

The 2017 Subaru Legacy (BN/BS) factory repair manual, made for your VIN from the same Subaru service information dealer technicians use: step-by-step repair procedures, specifications and wiring diagrams for your exact Legacy. The 2017 Legacy was offered with two engines (listed below); your manual covers the one your VIN shows.

Bought from a Google Top Quality Store, owned by you. No account to renew and no access that runs out: the manual stays on your computer, phone or tablet.

The difference you get

• Manufacturer data: written by Subaru, not rewritten by a third-party publisher
• Matched to your VIN, so you don't wade through versions you don't own
• Clickable hyperlinks throughout the PDF: from a repair step straight to the diagram or torque table it mentions, with bookmarks and full-text search on top. Few manuals sold online have this
• Wiring included: diagrams, connector pinouts and component locations
• A real person checks every order and the VIN before the manual is built
• Online since 2015, rated a Google Top Quality Store

Owner's manual or repair manual?

The owner's manual in the glovebox explains the controls and the service intervals. This is the other book, the one technicians work from:

• Owner's manual: controls, warning lights, maintenance schedule, fluid types
• Factory repair manual: how to take parts out and put them back, the torque for every bolt, fault codes and complete wiring diagrams

Your 2017 Legacy is from the sixth-generation Legacy (BN/BS), built for model years 2015–2019. Years of the same generation share most procedures; equipment and electrical details still change from year to year, so the manual follows your VIN.

Engines offered

• 2,5 liter engine, CVT transmission, AWD
• 3,6 liter engine, CVT transmission, AWD

Not sure which version you have? You don't need to know: the VIN tells us, and the manual is built for it.

• Engine and transmission mounts
• Ball joints, tie rod ends and control arm bushings
