Infiniti ex 35 manual

Make sure to avoid damaging pipes, tubes, etc. Always use safety stands when you have to get under the vehicle. Jack up be carefully. Safety stand point and lift up point front 2. Safety stand point and lift up point rear 3. Garage jack point front 4. 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 dam- age to the transmission. 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 vehi- cle using the vehicle tie downs or recovery hooks. Never pull on the hook at an angle. Always follow the dolly manufacture's recommendations when using their product. 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 vehi- cle.

Service History and if any After Market Accessories have been installed. STEP 2 Operate the system, road test if necessary. Verify the parameter of the incident.

STEP 4 Inspect the system for mechanical binding, loose connectors or wiring damage. Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness Lay- outs.

STEP 5 Repair or replace the incident circuit or component. STEP 6 Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inad- vertently created a new incident during your diagnosis or repair steps. If water is found in the control unit, dry it fully and then install it in the vehi- cle. Damage to the seal between wire and connector may result. Do not insert any object other than the same type male terminal into female terminal.

Tool number Kent-Moore No. To probe each terminal, remove the connector retainer to make con- tact space for probing. Assemble a male terminal and approx. NOTE: Use a male terminal which matches the female terminal. Disconnect the suspected faulty connector and hold it terminal side up. While holding the wire of the male terminal, try to insert the male terminal into the female terminal. While moving the connector, check whether the male terminal can be easily inserted or not. Waterproof Connector Inspection If water enters the connector, it can short interior circuits.

This may lead to intermittent problems. Check the following items to maintain the original waterproof characteristics. If the seal is missing, the waterproof performance may not meet specifications. Whenever connectors are reconnected, make sure the rubber seal is properly installed on either side of male or female connector. Be sure that the seal is installed properly. Terminal Lock Inspection Check for unlocked terminals by pulling wire at the end of connector.

An unlocked terminal may create intermittent signals in the circuit. If possible, re-create the conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. It is important for simulating the conditions of the problem. In such a case, you will want to check for a vibration related condition. Refer to the following illustra- tion. Gently shake each connector and harness while monitoring the system for the incident you are trying to duplicate.

This test may indicate a loose or poor electrical connection. Hint Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi- nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter- mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on related connectors in the system. This test may indicate a loose or poorly mounted sensor or relay.

Engine Compartment There are several reasons a vehicle or engine vibration could cause an electrical complaint. To inspect components under the hood, start by verifying the integrity of ground connections. Refer to Ground Inspection described later.

First check that the system is properly grounded. Then check for loose connection by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the wiring for continuity. Behind the Instrument Panel An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi- cle vibration can aggravate a harness which is routed along a bracket or near a screw.

If the wiring runs under seating areas, inspect wire routing for possible damage or pinching. In such cases you will want to check for a heat sensitive condition. The first is to arrange for the owner to leave his car overnight. Make sure it will get cold enough to demonstrate his complaint. Leave the car parked out- side overnight. In the morning, do a quick and thorough diagnosis of those electrical components which could be affected.

Reinstall the part into the car and check for the reoccurrence of the incident. If it occurs, repair or replace the component. In such cases the incident could be caused by water intru- sion on an electrical part. This can be simulated by soaking the car or running it through a car wash. In these cases you may have to keep the car overnight to make a proper diagnosis.

Before beginning it is important to have all available information on the system to be tested. Also, get a thor- ough understanding of system operation. Then you will be able to use the appropriate equipment and follow the correct test procedure.

Gently shake the wiring harness or electrical component to do this. This will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your work- ing knowledge of the system. Continuity Check Method The continuity check is used to find an open in the circuit.

The digital multimeter DMM set on the resistance function will indicate an open circuit as over limit no beep tone or no ohms symbol. Make sure to always start with the DMM at the highest resistance level. To help in understanding the diagnosis of open circuits, please refer to the previous schematic. Little or no resistance will indicate that por- tion of the circuit has good continuity.

If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resis- tance condition.

If there were an open in the circuit, the DMM would indicate an over limit or infi- nite resistance condition. Voltage Check Method To help in understanding the diagnosis of open circuits please refer to the previous schematic. In any powered circuit, an open can be found by methodically checking the system for the presence of voltage.

This is done by switching the DMM to the voltage function. OPEN A circuit is open when there is no continuity through a section of the circuit. Any powered circuit can be diagnosed using the approach in the previous example. Connect the other probe to a known good ground. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity.

SW1 open, relay disconnected and solenoid discon- nected powered through the fuse. Ground connections are often exposed to moisture, dirt and other corrosive elements. The corrosion rust can become an unwanted resistance.

This unwanted resistance can change the way a circuit works. 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 eye- let make sure no ground wires have excess wire insulation. A voltage drop in a circuit is caused by a resistance when the circuit is in operation. 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. Such resistance variation may be caused by poor connection, improper installation, improper wire gauge or corrosion. 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.
