Yes, the manual includes full coverage for both the 6.6L Duramax diesel engine and the dual rear wheel (DRW) drive system used in the 2022 GMC Sierra 2500HD and 3500HD models.
It provides:
• Complete service procedures for the L5P 6.6L diesel, including fuel injection, turbocharger, emissions systems (DPF, DEF, SCR), and cooling
• Diagnostic workflows, wiring diagrams, and sensor pinouts specific to diesel configurations
• Step-by-step instructions for DRW-specific components, including rear axle servicing, wheel hub assemblies, and brake systems
• Torque specifications and maintenance intervals for heavy-duty configurations
This is the factory-issued documentation used by GM service technicians for both powertrain and chassis systems.
