2005 infiniti fx35 service manual

This unwanted resistance can change the way a circuit works. Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even when the ground connection looks clean, there can be a thin film of rust on the surface.

Make sure all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one eyelet make sure no ground wires have excess wire insulation. Voltage Drop Tests Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage drop in a circuit is caused by a resistance when the circuit is in operation.

Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire will give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire is not able to carry the current.

The single strand will have a high resistance to the current. This will be picked up as a slight voltage drop. The positive lead of the DMM should be closer to power and the negative lead closer to ground. Note in the illustration that there is an excessive 4. The Computer Controlled system operations can be adversely affected by any variation in resistance in the system. Such resistance variation may be caused by poor connection, improper installation, improper wire gauge or corrosion.

The step by step voltage drop test can identify a component or wire with too much resistance. The voltage value is based on the body ground. Control unit does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to light up the lamp. Therefore, the control unit does not control ground to light up the lamp. Never reverse polarity of battery terminals. Install only parts specified for a vehicle.

Before replacing the control unit, check the input and output and functions of the component parts. Do not apply excessive force when disconnecting a connector. If a connector is installed by tightening bolts, loosen bolt mounting it, then take it out by hand. Before installing a connector, make sure the terminal is not bent or damaged, and then correctly connect it. When installing a connector by tightening bolts, fix it by tightening the mounting bolt until the painted projection of the connector becomes even with the surface.

For removal of the lever type connector, pull the lever up to the direction pointed to by the arrow A in the figure, and then remove the connector. For installation of the lever type connector, pull down the lever to the direction pointed by the arrow B in the figure, and then push the connector until a clicking noise is heard. Do not apply excessive shock to the control unit by dropping or hitting it.

Be careful to prevent condensation in the control unit due to rapid temperature changes and do not let water or rain get on it. If water is found in the control unit, dry it fully and then install it in the vehicle.

Be careful not to let oil to get on the control unit connector. Avoid cleaning the control unit with volatile oil. Do not disassemble the control unit, and do not remove the upper and lower covers. When using a DMM, be careful not to let test probes get close to each other to prevent the power transistor in the control unit from damaging battery voltage because of short circuiting. When checking input and output signals of the control unit, use the specified check adapter.

When it is connected with a diagnostic connector equipped on the vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various kinds of diagnostic tests. Current self-diagnostic results and all trouble diagnostic records previously stored can be read.

Individual control unit number can be read. Use of another battery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if mistreated. Do not recharge, disassemble or dispose of in fire. Keep the battery out of reach of children and discard used battery conforming to the local regulations.

If necessary, turn on the ignition switch. Power supply and ground circuit for the control unit of the system For detailed circuit, refer to wiring diagram for each system. Open or short circuit CAN communication line. The actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here.

Make sure to avoid damaging pipes, tubes, etc. Always use safety stands when you have to get under the vehicle. WARNING: When lifting the vehicle, open the lift arms as wide as possible and ensure that the front and rear of the vehicle are well balanced.

When setting the lift arm, do not allow the arm to contact the brake tubes, brake cable, fuel lines and sill spoiler. Towing is in accordance with Towing Procedure Manual at dealer.

If any unit is damaged, dollies must be used. This may cause serious and expensive damage to the transmission. If it is necessary to tow the vehicle with the front wheels raised, always use towing dollies under the rear wheels. Never secure the steering wheel by turning the ignition key to the LOCK position. This may damage the steering lock mechanism. If the speed or distance must necessarily be greater, remove the propeller shaft before towing to prevent damage to the transmission.

Securely install the vehicle recovery hook stored with jacking tools. Make sure that the hook is properly secured in the stored place after use. This could cause them to explode and result in serious injury. Parts of your vehicle could also overheat and be damaged. Otherwise, the vehicle body will be damaged. Never tow the vehicle using the vehicle tie downs or recovery hooks. Never pull on the hook at an angle.

If the vehicle is stuck in sand, snow, mud, etc. Turn off the Vehicle Dynamic Control System. Make sure the area in front and behind the vehicle is clear of obstructions.

Turn the steering wheel right and left to clear an area around the front tires. Slowly rock the vehicle forward and backward. Shift back and forth between R reverse and D drive.

Apply the accelerator as little as possible to maintain the rocking motion. Release the accelerator pedal before shifting between R and D. If the vehicle can not be freed after a few tries, contact a professional towing service to remove the vehicle. Special parts are excluded. This standard is applicable to bolts having the following marks embossed on the bolt head. Refer to the following chart for help in selecting the appropriate chemical product or sealant.

Product Description. For metal-to-metal flange sealing. Can fill a 0. Provides instant sealing on any threaded straight or parallel threaded fitting. Thread sealant only, no locking ability. Do not use on plastic.

All emission related terms used in this publication in accordance with SAE J are listed. Removal and Installation Checking Drive Belts E If steering wheel rotation is required when battery power is interrupted, follow the procedure below before starting the repair operation. Before starting work, make sure no fire or spark producing items are in the work area.

Release fuel pressure before disconnecting and disassembly. After disconnecting pipes, plug openings to stop fuel leakage. When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or uninstructed operations.

Exercise maximum care to avoid damage to mating or sliding surfaces. Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins, make sure that dowel pins are installed in the original position. Cover openings of engine system with a tape or equivalent, if necessary, to seal out foreign materials. Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly. When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally opposite, and so on.

If the order of loosening is specified, do exactly as specified. Power tools may be used in the step. Before repairing or replacing, thoroughly inspect parts. This is only true if you do not have the practical resources and handy tools during state of emergency. This manual will surely pay off when you perform the first oil change, spark plug change, or air filter change!

Another reason why you should grab this Infiniti FX35 FX45 repair manual fast because it includes easy-to-follow instructions on which tools are being used and illustrations on how repairing is being performed.

Just imagine how much you can save by performing simple repairs by you own every now and then. Many smart peoples buy this manual to handle inevitable events when it happens.
