We remove the airbag when removing the steering wheel, when the airbag deploys, or when the airbag malfunctions.
The presence of an airbag on the vehicle is confirmed by the inscription “AIRBAG” on the cover of the driver’s airbag module installed on the steering wheel, the inscription “SRS/AIRBAG” on the cover of the front passenger’s airbag module located in the instrument panel, and the inscription “AIRBAG” on the label of the front airbag tape. seat belt.
The condition of the SNAP is monitored by a signaling device located in the instrument cluster, which, after turning on the ignition, in the absence of a malfunction, should turn on for 3–4 seconds and turn off.
If there is a malfunction of the SNBP:
— the indicator turns on again after 3–4 seconds of lighting when the ignition is turned on or while the vehicle is moving and remains on until the malfunction is eliminated;
— when the ignition is turned on, the indicator does not turn on.
Flashing of the indicator after turning on the ignition indicates that the SNAP control unit is in a locked state.
The factory recommends replacing airbag modules after ten years from the date of manufacture. The date is indicated on the airbag module label.
The driver airbag module uses a pyrotechnic gas generator, which consists of a housing filled with a solid pyrotechnic substance and an igniter. In it, gas is produced when a pyrotechnic substance is burned.
Removing the driver's airbag
We prepare the car for the job.
Turn off the ignition and disconnect the negative cable from the battery.
After disconnecting the battery, you need to wait 10 minutes until the airbag activator capacitor is completely discharged.
The driver's airbag is mounted on the steering wheel with two plastic hooks 2 and 4, Figure 2, and two positioning hooks 8.
The hooks of the pillow fit into the holes in the bracket for fixation 2 and are fixed with spring clips. The airbag latches fit into recesses 3, Figure 3, on the steering wheel.
We set the steering wheel to the “straight” position and, by removing the key from the ignition switch, fix this position.
Use a thin flat screwdriver to pierce the hole marked on the steering wheel. We also pierce a hole on the other side of the steering wheel.
Using two screwdrivers, press out the spring clamps through the holes (in the picture with the airbag removed), pulling the airbag towards you, we remove the hooks of the airbag from engagement with the clamps on the steering wheel.
We pull the pillow towards ourselves, overcoming the resistance of the clamps, and remove it from the recesses of the steering wheel.
Move the airbag away from the steering wheel
Disconnect the horn wire ends
Use a screwdriver to pry the clamp out of the wire block
Disconnect the wire block from the airbag connector
Removing the airbag
The removed airbag should be stored in a place protected from moisture and excessive heat, with its cover facing up.
Installing the airbag is done in the reverse order.
We connect the block of wires to the airbag connector, insert the lock into the block.
We connect the wire lugs to the terminals of the signal switch.
We install the cushion on the steering wheel so that the cushion clamps fit into the recess of the steering wheel, and the hooks of the cushion fit into the corresponding holes in the steering wheel.
Press the cushion until the hooks of the cushion snap into place with the steering wheel latches.
In a factory or car service center, plastic wedges are used to remove airbags (Figure 11).
And devices for removing pillows are used (Figure 12).
Passenger airbag
The passenger airbag module (PAIBP), Figure 13, consists of a gas generator 1, a housing 3, with an airbag folded in it, and a facing cover 7.
The gas generator consists of a housing filled with compressed inert gas and a pyrotechnic substance, and an igniter fuse.
An igniter is a device with electrical resistance and a pyrotechnic substance.
After receiving an electrical signal from the control unit, the electrical resistance heats up and ignites the pyrotechnic substance of the igniter, followed by ignition of the bulk of the pyrotechnic substance of the gas generator.
Removing the passenger airbag
We remove the instrument panel as described in the article - How to remove the instrument panel of a Lada Granta.
Disconnect block 1, Figure 14, of the instrument panel wiring harness from the MNPBP.
Using a 13 socket, unscrew two bolts 4
Press the clamps 5, disconnect and remove the passenger airbag module
Place the failed module on a flat surface with the facing cover facing up.
Installing the airbag module
Before installing the module, you must ensure that there is no damage.
Install the airbag module in reverse order
The tightening torque of the two bolts securing the airbag module is 13 – 15 Nm (1.3 – 1.5 kgcm).
Lada Granta Cosmos › Logbook › airbag - or crickets again!
In fact, colleagues, the question is in the title, but I’ll repeat: I made the noise of the doors, enjoying the silence, and suddenly, quite recently, a cricket with some kind of metallic sound settled in with me... the sound comes from the roofing felts only from the front panel, but is felt somewhere next to the passenger’s pillow. I removed the front panel, what remains for our client to do is glue it with Madeleine, the radio sliders are firmly attached, in general the panel has anti-sound
