Infiniti G35 2004 Technical Manual

If you’ve ever had an aftermarket manual steer you wrong on an SRS circuit or a door lock actuator because they reused some Toyota diagram—welcome to the reason you’re here. The Infiniti G35 2004 Technical Manual is the only document that gets the factory stamp. 194 pages of OEM-only content, not a generic reprint. This is the book that tells you which wire in the 20-pin BCM connector carries the CAN-H signal and what voltage it should read when the key is in the ON position. It lists the exact special service tools you need before you even start pulling trim.

4 Systems Covered in This Manual

The manual splits into four main technical blocks: body lock & security (including power door locks and remote keyless entry), the supplemental restraint system (SRS) with airbag and seat belt pre-tensioner precautions, wiring diagnostics and CAN communication, and the hood/radiator core support mechanical adjustments. Each block has its own work flow, component location diagrams, and terminal reference charts. The squeak and rattle trouble diagnosis section alone saves you a full day of chasing noises in the instrument panel, doors, trunk, sunroof, seats, and underhood. Page 6 starts the diagnostic work flow sequence—customer interview, duplicate noise, check bulletins, locate root cause, repair, confirm.

SRS Precautions – Don’t Touch an Airbag Without This

The first pages of the manual hammer home SRS safety. You get the factory wording on how to disable the system, what tools are prohibited near an undeployed airbag, and the exact steps for battery service to avoid accidental deployment. The manual repeats: disconnect the negative battery cable and wait at least three minutes before any SRS component work. That’s not advice from a forum—it’s the OEM spec. Ignoring it can cost you a deployed bag and a shop full of flying dashboard parts. I’ve seen it happen. This is the part that makes aftermarket manuals dangerous—they often leave out the SRS diagnostic flow and just tell you to “remove the module carefully.”

Wiring Diagrams: Factory Schematics for the G35

The wiring section is where the manual proves its value. Four separate wiring diagrams for the power door lock system (FIG. 1 through 4) plus four more for the remote keyless entry system. Each diagram includes pinouts for the BCM, IPDM E/R, combination meter, and power window main switch. The manual gives terminal and reference values—expected voltage or resistance at each pin under specific key and switch states. CAN communication unit diagrams show both Type 1 and Type 2 system diagrams with input/output signal charts. If you need to trace a door lock actuator circuit or figure out why the keyless entry doesn’t set off the horn, you don’t guess—you open the manual to the wiring diagnosis section and follow the trouble diagnosis symptom chart.

Audience Fit: Who Needs This 2004 Technical Manual?

D.I.Y. owners who want to fix their own G35 without paying a dealership two hours of diagnostic time. Home garage enthusiasts who already own a multimeter and a basic socket set. Beginners who need the step-by-step removal and installation sequences for the hood, hood lock control, and radiator core support. The manual assumes you can read a schematic and turn a wrench, but it doesn’t assume you have the factory service bulletin database memorized. The 194 pages are dense—no filler, no “safety tips” that repeat every page. Each section ends with a diagnostic worksheet or a symptom chart so you can document what you did and move to the next test.

Does This Manual Cover the Power Door Lock System?

Yes, thoroughly. The power door lock system chapter runs from component location through system description (including power window serial link and key reminder door system), CAN communication, schematic, wiring diagrams, BCM terminal reference values, CONSULT-II function, work flow, fuse check, component tests for door switches, key switches, door lock actuators, fuel lid lock actuator. The remote keyless entry chapter adds hazard/horn reminder, auto door lock operation, map lamp/keyhole illumination, panic alarm, trunk lid opener, and keyless power window down. Every test procedure includes the OEM pass/fail criteria—not just “check for continuity” but the specific terminal and reference value for the BCM or IPDM E/R. That level of detail keeps your diag time below 30 minutes on most lock system complaints.

Does this manual include torque specifications for the hood hinges?

Yes, the hood fitting adjustment section specifies bolt torque during installation. The manual lists the values in the removal and installation procedure – not aftermarket approximations.

Are the wiring diagrams in color or black-and-white?

They are black-and-white line drawings with clear labels for wire colors (e.g., “L/W” for blue/white) and connector terminal numbers. The key to interpreting the diagrams is printed at the beginning of the wiring section. If you need to probe the BCM connector, the manual shows the exact cavity view and the corresponding terminal number for each circuit. The diagrams are factory-original, so every splice, ground point, and connector location matches the actual car. I’ve used these to trace a shorted door lock actuator wire on a 2004 G35 coupe – took me 15 minutes to find the break in the driver’s door boot because the manual had the wire colors and routing right. No aftermarket CD I’ve seen gets that right.

If you’re tired of chasing your tail with generic internet diagrams and third-party repair guides that leave out the SRS disable procedure, this is the document that will get the job done right.
