The steering wheel has a row of control buttons to which connecting wires are connected. In order to ensure reliable contact in all circuits when the steering wheel is turned, a device called a "clock spring" is used. This name is based on the similarity of the spiral flexible contact buses of the device with a clock spring. Essentially, this device is a rotating contact joint. This type of device does not use sliding contacts. Freedom of rotation of the steering wheel without breaking contact is ensured by a sufficient length of the spiral package of flexible tires. This length should be enough to turn the steering wheel 3-3.5 turns in each direction.
Attention!
- Before removing the airbag, you must turn off the power supply to the vehicle's electrical system and then wait at least 1 minute.
- When removing the steering wheel, special care must be taken when removing the driver's airbag.
- Disassembling and reassembling the airbag may impair the system's functionality, which could result in serious injury or death.
- Incorrect connection of the airbag wiring may cause the airbag to deploy. If a fault is found in the connecting elements, replace the wiring harness.
- Do not use an ohmmeter to test the airbag - this may cause it to deploy. To do this, you need to use the on-board diagnostics system in a service station.
- When carrying the airbag, hold it so that the operating side is not facing you.
- Do not place the pillow with the working side down, since if it is accidentally activated, the pillow body may be thrown away by the pillow unfolding in a random direction and cause injury.
