Introduction to the dismantling process
Car steering work Nissan Note require extreme care, since a passive safety system is integrated into the design of the unit. Many car owners are faced with the need to remove the steering wheel to replace an airbag, install a sports steering wheel, or carry out complex electrical repairs.
The procedure is simple, but carries hidden risks associated with highly sensitive components. An incorrect action may result in airbag deployment or damage to the airbag contact group (spiral).
In this material we will analyze all stages, from preparing tools to final assembly, paying special attention to safety. You will learn how to bypass standard clamps and what to do if the steering wheel is stuck to the shaft.
Preparing tools and safety precautions
Before touching the steering wheel, you need to make sure that you have completely isolated the vehicle's on-board network. This is a critical stage on which your safety and the safety of electronic components depends.
To work, you will need a standard set of locksmith tools, but special attention should be paid to sockets and keys. Standard set for Nissan Note includes 10, 12, 14 and 18 millimeter sockets, as well as flat and Phillips screwdrivers.
You will also need plastic cards for removing the trim to avoid scratching the decorative elements of the interior. If you plan to remove the steering wheel to replace the pad, be sure to have dielectric gloves.
Start by disconnecting the battery terminal. Remove the negative terminal and wait at least 15-20 minutes. This time is necessary for the capacitors in the SRS system to discharge to prevent accidental deployment of the airbag.
⚠️ Attention: Never work on the SRS (airbag) system with the battery connected, even if the key is removed from the ignition. The remaining charge in the capacitors can cause the pillow to explode.
☑️ Preparation for dismantling the steering wheel
Removing the airbag and decorative elements
The most important step is removing the airbag. On Nissan Note Different generations (N15, N16, N17) methods of accessing the latches may differ, but the principle remains similar.
Usually the clamps are located on the back of the steering wheel. You need to carefully insert a thin screwdriver or a special key into the technological hole and press the latch. Do this on both sides, one at a time, so that the pillow comes out evenly.
After you hear the click of the latch being released, gently pull the pillow towards you. Do not pull too hard as the wiring inside may be too short or fragile.
Disconnect the wiring harness connectors from the airbag. Be careful: the connectors often have latches that need to be released first. Do not pull on the wires, only pull on the plastic housing of the connector.
- 🔧 Use thin screwdriver to access the fasteners from the rear of the steering wheel.
- 🔌 Disconnect carefully connectors wire harness without pulling on the wires themselves.
- 🛡️ Immediately after removing, put the pillow face up on a soft surface.
What to do if the cushion doesn't come out?|Sometimes the clips can get stuck due to dust or aging plastic. In this case, do not use excessive force. Try rocking the pillow a little while pressing the latches on both sides. If all else fails, check to see if the wiring harness inside the steering wheel is kinked, which often happens when used carelessly.-->
It is important to understand that after removing the airbag you will have access to the steering wheel mounting bolt. However, before turning the nut, you need to make sure that the coiled cable will not be damaged when turning the steering wheel in the future.
⚠️ Attention
⚠️ Attention
It is strictly forbidden to turn the steering shaft or steering wheel after removing the airbag if the spiral cable (cable) has already been disconnected. This will lead to broken contacts and failure of the airbag control unit.
Removing the mounting bolt and the steering wheel itself
After removing the airbag, you will see the center steering wheel mounting bolt. On most models Nissan Note a bolt with a hexagon or torx head is used, less often a Phillips screwdriver.
The key feature is that this bolt is tightened with enormous force. Therefore, you will need a quality wrench and extensions. It is unlikely that you will be able to unscrew it simply by hand.
Before unscrewing the central bolt, be sure to make a mark on the steering wheel and steering column in order to maintain the factory position of the steering wheel during installation. This will save you time adjusting wheel alignment.
After unscrewing the bolt, do not remove it completely immediately. Leave it on for a few turns so the handlebars don't fall on your feet when you start to pull it. The steering wheel sits very tightly on the splined shaft, and its removal may require effort.
- 🔩 Use extension wrench to create sufficient leverage.
- 📏 Be sure to apply label on the shaft before dismantling.
- 🛑 Do not release the bolt completely until you are ready to hold the steering wheel.
- Socket head with knob
- Ratchet head
- Universal key
- Flat head screwdriver
If the steering wheel does not budge, use a special puller. But at home, the method of gentle rocking is often used. Lightly twitch the steering wheel up and down and left and right, applying force to yourself. Splines tend to “stick” due to time and vibrations.
Never hit the steering wheel or shaft with a hammer. You can damage the steering column bearings or deform the shaft itself, which will lead to play and vibrations when driving.
⚠️ Attention: If the steering wheel does not come off after removing the bolt, do not use a pry bar between the spokes and the steering column. This is guaranteed to break the plastic and ruin the appearance of the interior. Use the puller or rocking method only.
Working with a contact spiral (loop)
After removing the steering wheel, you will see a spiral cable (cable), which is responsible for transmitting signals from the buttons on the steering wheel and the airbag to the control unit. This element requires the utmost care.
The spiral has a limited range of rotation. If you turn the steering shaft all the way left or right without the steering wheel, you will break the thin wires inside the cable. This will cause the airbag error to appear and the buttons not to work.
To safely dismantle the cable, it is necessary to fix the steering column in the neutral position. If you plan to remove the cable itself, make sure that the steering wheel is level and the wheels are also in the "straight" position.
The cable is usually secured to the column with two bolts. By unscrewing them, you can carefully remove the connectors. Make sure that the spiral mechanism does not rotate spontaneously.
- 🔄 Fix the steering shaft in neutral position before working with the cable.
- ⚡ Maintain integrity contact groups on the connectors.
- 🚫 Do not rotate the column shaft all the way when removed steering wheel.
| element | Tool | Special requirements |
|---|---|---|
| Center bolt | 18mm head, knob | High torque |
| Cushion clamps | Thin screwdriver | Be careful not to break the plastic |
| Cable bolts | Phillips screwdriver | Fixing the shaft from rotation |
| Connectors | Hands (no tools) | Press the latches, do not pull the wires |
The main problem when removing the steering wheel is maintaining the integrity of the spiral cable. Always keep the steering shaft in neutral when the steering wheel is removed to avoid breaking the contacts inside the cable.
Troubleshooting problems during removal and features of models
Owners Nissan Note may face a number of specific problems. The most common is a too-tightened central bolt. On used cars, the metal can “seize” due to corrosion or simply from time to time.
In such cases, use a penetrating lubricant (WD-40 or equivalent). Spray the threads generously and wait 10-15 minutes. This will help soften the dirt and make it easier to unscrew.
Another problem is broken airbag latches when trying to remove it without special keys. If the plastic breaks, you will have to either replace the fasteners or carefully secure the pillow with electrical tape when reassembling it so that it does not dangle.
On models with a keyless entry system (Smart Key), there is a nuance: when removing the steering wheel, the signal from the engine start button may disappear. Make sure you haven't lost the chip key and know how to start the car in emergency mode if the electronics get confused.
For owners of sports versions or tuned steering wheels, it is worth remembering the additional bolts for fastening the spokes, which may be hidden under decorative plugs. They must be carefully pryed and removed before unscrewing the main fasteners.
Why does the airbag lamp light up after assembly?|Most often this is due to poor connector contact or damage to the spiral cable. Check that the connectors are fully inserted and that their latches are latched. If the problem persists, you may have turned the shaft when installing the steering wheel and broke the cable.-->
Checking functionality after installation
After you have returned the steering wheel to its place and tightened all the bolts, do not rush to start the engine right away. First check how the spiral works. Turn the steering wheel from side to side, listening for any crackling or squeaking noises inside the column.
Connect the battery and turn on the ignition. Look at the dashboard
The airbag light should come on for a few seconds and then go off. If it is constantly on or blinking, it means there is an error in the system.
Check the operation of all buttons on the steering wheel: volume, phone controls, cruise control. If some functions do not work, the problem may be poor contact of the buttons with the cable or a break in the cable itself.
If the airbag light is on, try resetting the errors through the diagnostic scanner. Sometimes it is enough to simply remove the battery terminal for 5 minutes after correct installation for the system to recheck the circuits.
- 🚗 Check the work buttons on the steering wheel before starting movement.
- 💡 Make sure the lamp SRS goes out after the engine starts.
- 🔊 Test it sound signals and the operation of the buzzer.
