2012 GMC Yukon XL 2500 Service and Repair Manual

This factory service and repair manual for the 2012 GMC Yukon XL 2500 describes a 4-door sport utility with a single flex-fuel engine, the 6.0L V8 of 364 cubic inches, naturally aspirated and built with overhead valves, sold in SLE and SLT trim.

Known issues on the 2012 Yukon XL 2500. Owner reports to NHTSA on this model year number 73, and they concentrate in three areas — 21 concern the air bags, nine the structure, and seven the electrical system. The manual answers all three: restraint-system procedures with the trouble codes that pinpoint a fault, structural and body repair specifications for the panels and frame, and full wiring diagrams with connector views for chasing an electrical circuit that only misbehaves intermittently.
