2006 Infiniti FX35 / FX45 Service Manual (P/N SM6E-1S50U1)

• Exact S50-series coverage: 2006 Infiniti FX35 models with the VQ35DE in U.S. 2WD or U.S./Canadian AWD form, plus 2006 FX45 models with the VK45DE and AWD. Every covered configuration uses the RE5R05A five-speed automatic transmission.
• Engine repair content is divided by VQ35DE and VK45DE. It covers engine removal, timing-chain and camshaft service, valve-clearance inspection and adjustment, cylinder-head disassembly, cylinder-block teardown and assembly, and piston and bearing selection.
• Transmission and driveline sections include RE5R05A stall, line-pressure, road, shift, and lockup testing; TCM and valve-body diagnosis; transmission removal for 2WD and AWD models; and full internal overhaul. The ETX13B transfer, F160A front final drive, R200 rear final drive, propeller shafts, axles, and drive shafts receive separate repair procedures.
• Chassis work extends through wheel alignment, front and rear suspension, hub and bearing service, power-steering gear and pump overhaul, hydraulic bleeding and pressure testing, and disc and parking brakes. VDC/TCS/ABS coverage includes wheel-sensor diagnosis, steering-angle neutral adjustment, and AWD deceleration-G-sensor calibration.
• Electronic and control-system diagnosis links ECM and TCM powertrain management with BCM/IPDM E/R body functions across the documented CAN configurations. Separate sections handle ASCD/ICC, TPMS, Intelligent Key/NATS, climate control, driver information, lighting, and audio/navigation/telephone faults through CONSULT-II routines, active tests, terminal values, DTC charts, and symptom-based fault isolation.
• Body and restraint sections move from door, glass, sunroof, seat, and trim removal to SRS and occupant-classification fault tracing. Collision repair coverage adds body alignment dimensions, corrosion protection, high-strength-steel cautions, and factory panel-replacement operations.

Coverage, Format, and Skill Level

This is the 4,463-page PDF set of the 2006 FX35/FX45 factory service manual, arranged as 42 factory sections plus quick-reference front matter across 43 files under Publication No. SM6E-1S50U1. The cover identifies a December 2005 edition with a December 2006 revision. With CONSULT-II routines, electrical test equipment, pressure gauges, pullers, presses, and Kent-Moore special tools assumed, the material is best suited to professional technicians and experienced DIY owners working in a properly equipped shop.

The repair depth reaches well beyond maintenance schedules. Engine sections include compression checks, oil-pressure diagnosis, cooling-system testing, fuel and EVAP work, engine removal, and internal inspection limits. Transmission coverage moves from OBD-II and no-scan-tool diagnosis through shift complaints and on-vehicle service to clutch, brake, planetary, oil-pump, and control-valve overhaul. Separate maintenance data covers factory fluids, capacities, service intervals, and inspection points for both engine builds and the applicable driveline.

Wiring, Diagnostics, and Adjustment Procedures

The electrical material pairs system descriptions with schematics, connector and pin-location views, power-and-ground checks, control-unit input/output tables, and diagnostic flow charts. Representative illustrations include the 2WD/AWD RE5R05A cross-sectional views, VQ35DE/VK45DE engine-control circuit diagrams, the ETX13B power-transfer diagram, the VDC/TCS/ABS hydraulic circuit, ICC functional and wiring diagrams, and CAN-network schematics with harness locations.

Factory setup work includes ECM VIN registration; accelerator-pedal released-position, throttle-closed-position, and idle-air-volume learning; ICC laser-beam aiming; TPMS transmitter ID registration; and Intelligent Key/NATS diagnostic functions. The manual identifies dedicated equipment such as the J-34301-C transmission line-pressure gauge set, J-45718 ICC target board, and J-45295 TPMS activation tool. Service-data sections supply component torque tables, approved-fluid and capacity data, pressure-test specifications, wheel-alignment values, wear and clearance limits, final-drive preload and runout data, and electrical reference values.

Shop Cautions

The RE5R05A section warns that non-specified ATF can damage the transmission and explains why a normal drain leaves old fluid in the torque converter and cooler; dedicated fluid-replacement and cooler-cleaning procedures are provided. Separate cautions address mixed or contaminated refrigerant that can lead to compressor failure and mismatched AWD tires that place excessive force on the driveline and cause longitudinal vibration.

Read the GI precautions before beginning any repair. SRS service is specifically restricted to an authorized Nissan/Infiniti dealer, the ICC laser must never be viewed directly during aiming, and refrigerant work requires approved recovery and recycling equipment.
