Removing the driver's frontal airbag module and SRS coiled wire.
1 - driver front airbag module, 2 - steering wheel lock nut, 3 - steering wheel, 4 - SRS coiled wire, 5 - steering column.
Attention: when performing any work on the SRS system, follow the instructions in section "Operation and Maintenance Safety Precautions".
Removal and installation
1. Disconnect the wire from the negative battery terminal and securely insulate the wire connector.
Attention: after disconnecting the battery cable, wait at least 30 seconds before proceeding with further work.
2. Remove the side protective covers of the steering wheel, unscrew the bolts of the airbag module with a key for an internal hexagon.
3. To disconnect the SRS coiled wire connector from the airbag module, push the retainer towards the outside and release it.
Caution: To avoid damage to the connector, do not apply excessive force when disconnecting the connector connecting the coiled wire and the airbag module.
4. Remove the driver's frontal airbag module.
Attention: the removed airbag module should be stored in a clean, dry place, with a protective pad (front side) up.
5. Using the special tool, remove the steering wheel.
Attention: do not knock on the steering wheel when removing, as the steering column folding mechanism may be damaged.
6. Installation is made in an order, the return to removal. When installing, pay attention to the installation operation of the coiled wire.
- A) Check that the front wheels are parallel to the longitudinal axis of the vehicle.
- b) To set the coiled wire to the neutral position, turn the top of the wire clockwise until it stops. From this position, rotate its top about 3 turns counterclockwise and align the alignment marks (→←).
- V) Install the SRS coiled wire to the vehicle.
Caution: If the coiled wire alignment marks are not fully aligned when turning, steering wheel rotation may not be complete or the SRS wiring will be disconnected.
Spiral wire SRS.
1 - cover, 2 - rotor, 3 - internal gear, 4 - external gear, 5 - lower part of the housing, 6 - alignment marks, 7 - upper part of the housing.
Examination
Airbag module
Caution: Never attempt to measure the resistance of a component's igniter circuit, even when using a recommended tester. Unauthorized operation of a component may occur when a circuit tester measures the resistance of a circuit (airbags).
1. Check up a protective overlay of the module of a pillow of safety on absence of cracks, dents and deformation.
2. Check the air bag module for dents, cracks or deformations.
3. Check the condition (no kinks or pinching) harnesses, no damage to the latches, no damage to the connectors and no deformation of the connector pins.
4. Check the body of the inflatable device (gas generator) for dents, cracks or deformations.
5. Install the airbag module on the steering wheel and check the fit (in size and fit) module and steering wheel.
A. Airbag module
6. If at least one of the checked parts is found to be defective as a result of the check, then replace the airbag module with a new one.
Spiral wire SRS
1. Check that the coiled wire connectors and protective tubes are not damaged, and that the connector pins are not deformed.
2. If at least one of the defects is found as a result of the checks. then replace the SRS coiled wire with a new one.
