2006 Nissan Maxima 3.5 SE and 3.5 SL A34 Service Manual (P/N SM7E-1A34U0)

• Covers 2007 Nissan Maxima A34 4-door sedans equipped with the VQ35DE 3.5L V6, RE0F09B CVT, 2-wheel drive, and left-hand drive. The model-variation data distinguishes 3.5 SE and 3.5 SL configurations, option packages, and USA, Canada, and Mexico destination codes.
• Nissan factory Service Manual, Edition/Revision May 2006, Publication No. SM7E-1A34U0. The May 2006 date is the publication revision date; the manual itself states that it covers the 2007 Maxima.
• The supplied PDF set is organized into 39 section files totaling 2,901 PDF pages. Its scope runs from engine and CVT repair through axles, suspension, brakes, steering, SRS, body systems, automatic A/C, starting/charging, lighting, driver information, CAN, audio/navigation/telephone, power supply and grounds, and scheduled maintenance.

Diagnostic and Control System Overview

Trouble diagnosis is built around the actual vehicle control architecture rather than generic fault-code lists. The engine and CVT sections include CONSULT-II and OBD-II/GST diagnosis, DTC confirmation procedures, reference values, data-monitor functions, fail-safe information, symptom work flows, and circuit checks. Separate sections cover BCM functions, IPDM E/R power distribution, ABS/TCS and VDC diagnosis, SRS self-diagnosis, tire-pressure monitoring, Intelligent Key/body security functions, and CAN network fault isolation.

The automatic climate-control material from the older description is still here, but it is only one part of the manual. The A/C section explains the dedicated LAN between the unified meter and A/C amp., mode door motor, air mix door motor, and intake door motor. Each door motor uses its own LCU address, opening-angle data, position feedback, and error checking. Built-in A/C self-diagnosis checks sensor circuits, door positions, actuator operation, and sensor temperatures, while the refrigeration section adds leak detection and performance-test diagnosis.

Representative technical views and electrical references include “Cross-sectional View - RE0F09B,” “Wiring Diagram — A/C,A —,” “CAN System Specification Chart,” “Wiring Diagram — CAN —,” “Wiring Diagram — VDC —,” and “Wiring Diagram — SRS —.” These are tied to connector layouts, terminal reference values, component locations, and diagnostic procedures rather than being stand-alone illustrations.

Technical Specifications and System Data

The factory repair procedures cover work an owner would commonly send to a shop: VQ35DE timing-chain service, camshaft and valve-clearance work, cylinder-head repair, engine assembly removal, cylinder-block disassembly/inspection, CVT stall and line-pressure testing, TCM and shift-control diagnosis, transaxle removal and installation, ABS/TCS/VDC diagnosis, SRS component service, A/C compressor and refrigerant-line work, and steering/suspension component repair. The manual also identifies dedicated service tooling, including the KV101J0010 (J-47242) engine support table, ST10120000 (J-24239-01) cylinder-head bolt wrench, OTC3492 CVT line-pressure gauge set, and KV991J0130 (ACR2005-NI) A/C recovery/recycling/recharging center.

Useful mechanical baselines are stated directly in the specifications. VQ35DE compression pressure is 1,275 kPa (185 psi) standard at 300 rpm, with a 981 kPa (142 psi) minimum and a 98 kPa (14 psi) maximum cylinder-to-cylinder difference. Cold valve clearance is 0.26–0.34 mm intake and 0.29–0.37 mm exhaust. For the RE0F09B CVT, stall speed is 2,700–3,250 rpm; reference line pressure is 750 kPa (108.8 psi) at idle and 5,700 kPa (826.5 psi) at stall.

Fluid and capacity data include 4.2 L (4 1/2 US qt) engine oil with filter change, 8.5 L (2 1/4 US gal) cooling-system capacity, and 10 L (10 5/8 US qt) of Genuine NISSAN CVT Fluid NS-2. The A/C charge is 0.55 ± 0.025 kg (1.21 ± 0.055 lb) of HFC-134a (R-134a), with 150 mL (5.03 US fl oz) of NISSAN A/C System Oil Type S. Accelerator pedal travel remains specified at 52.6–58.2 mm (2.07–2.29 in). Maintenance tables also call for platinum-tipped spark plug replacement at 105,000 miles and, under the listed severe-use conditions, CVT-fluid deterioration inspection with CONSULT-II at 60,000 miles.

Several repair cautions are especially specific to this model. Nissan warns that fluid other than NS-2 can damage the CVT. The A/C section prohibits mixing R-134a equipment or Type S oil with R-12 service equipment because contamination can lead to compressor failure. In the steering/SRS procedures, the spiral cable must remain correctly positioned because its rotation is limited; Nissan specifically warns that improper handling during steering-gear work can damage the SRS spiral cable.

Because working with pressurized A/C systems and sensitive vehicle networks carries inherent risks, this data is provided strictly for reference and shop-level maintenance and repair planning. Proper refrigerant recovery equipment is required before opening A/C lines, and the manual’s battery-disconnect and SRS precautions should be followed before servicing restraint-system circuits or components.
