Technical Specifications and System Overview
This 447-page factory reference is the primary diagnostic resource for the 1999–2002 Nissan Skyline R34 series. Covering the GF-HR34, GF-ER34, and GF-ENR34 chassis, it breaks down the systems for the 2-door Coupe, 4-door Sedan, and 25GT Turbo variants.
Printed directly from the original Nissan 8E-0R34J0 1998 publication, this indexed and fully searchable PDF allows you to instantly locate detailed terminal references and circuit layouts. It is available immediately upon checkout and stored in your account for secure backup. There are no DRM restrictions on printing, so you can easily run off the specific pages you need for the shop floor.
Coverage includes:
- RB20DE, RB25DE, and RB25DET powerplants
- Dual matic M-ATx and 4AT transmission systems
- 47 pages of exact wiring diagrams
- 48 pages of engine control diagnostic terminal references
- 24 pages of transmission shifting schematics
Engine Control and Transmission Diagnostics
Rather than basic overviews, this documentation dives straight into the ECM and TCM interaction. It maps out the exact signal flows for the mass air flow sensor, knock sensors, crank position signals, and solenoid-driven hydraulic actuators. You will find complete procedures for Diagnostic Test Mode I and II, alongside instructions for utilizing the Nissan CONSULT interface to run active tests and monitor system health.
Working with high-pressure fuel systems or probing ECM terminals carries inherent risks; always review the factory safety protocols outlined in these pages before executing live diagnostic tests or component replacements. The precise terminal layouts ensure you can accurately track signal voltage inputs and outputs without guessing pin locations.
Specification and Reference Values
Accurate diagnostics require exact baseline numbers. This manual provides the complete set of factory reference values for the R34 series, including:
- Cold Lash Intake Valve Clearance: 0.15–0.19 mm (0.006–0.007 in)
- Coolant System Capacity: 9.4 liters
- Base Fuel Pressure (at idle): 0.25 MPa (2.5 kg/cm2)
Like any professional OEM service publication, the documentation also covers in-depth shift schedule charts and line pressure test specifications vital for automatic transmission maintenance.
