Removal
1. Align the front wheels of the car.
2. Remove the steering wheel, see the relevant chapter.
3. Unscrew the contact coil from the steering wheel and carefully pull it out of the casing.
Attention! Unscrew the fastening bolts only enough to remove the contact spiral. Do not unscrew the bolts completely, so as not to change the position of the removed contact spiral.
4. Inspect the contact spiral for damage.
Installation
5. Make sure the front wheels of the vehicle are aligned and straight.
6. Insert the contact spiral until it stops and secure with bolts.
Attention! When installing, the contact spiral must be in the middle position. If the position of the spiral has been changed by accident, it must be installed in the middle position.
For the procedure for setting the coil to the middle position, see below.
7. Install the steering wheel, see the relevant chapter.
Warning! If the power supply to the steering wheel angle sensor is disconnected after its installation, the ABS system warning lights will light up (shock absorber stiffness regulator) or ESP (stability control system). The steering wheel angle sensor is attached to the contact spiral and is removed together with it.
8. After installing the steering wheel, activate the steering angle sensor by starting the engine and letting it idle.
9. Without turning off the engine, turn the steering wheel from lock to lock first to the left and then to the right. After this, the indicator light should go out.
The procedure for installing the contact spiral in the middle position
The contact spiral in the middle position ensures the perfect functioning of the airbag and turn signals. When disassembled, the contact spiral is fixed with mounting bolts.
10. Fully tighten the mounting bolts into the contact coil.
11. Turn the contact coil to the left until a slight resistance to winding appears. This means that the coil is fully wound.
12. Make 2.5-3 turns of the spiral to the right, i.e. the opposite side, so that you can loosen the tightening of the fastening bolts. As a result, the contact spiral will be fixed in the middle position.
Attention! Before full compression, the contact spiral rotates 5-6 revolutions.
