Volkswagen Golf / Golf GTI / Golf Variant. Manual - part 340

Caution

♦ Always note the correct installation position and only in‐

stall in the component location intended in the door.

♦ Protect the crash sensor from impact. Do not use a crash

sensor if it has fallen on the floor. When doing body work

on the door, the crash sensor should be removed.

♦ The crash sensor is calibrated to the volume of air inside

the door. If the door is deformed resulting in a reduced air

space inside the door, the function of the crash sensor will

be affected.

♦ Avoid contaminating the crash sensor. Do not use com‐

pressed air in the area surrounding the crash sensor.

Protect crash sensor from filings or shavings (for example,

when installing door speakers later). Do not use cavity

sealant or spray lubricant in the area of the crash sensor.

♦ Protect against heat and cold. Avoid heating, for example

when painting or doing other body work. Crash sensors

should not be subjected to temperatures below -40 °C (for

example, in non-climate-controlled airplane cargo holds).

♦ Protect the crash sensor from moisture when storing or

installing it.

For proper crash sensor function, effective door seal must be en‐

sured after installation. Note the following points:
♦ All components (for example, cover, speaker, door trim panel)

must be installed correctly.

♦ The door trim panel clips seal the system. If necessary, re‐

place the clips.

Passenger Occupant Detection System

Deactivation Additional Safety Precau‐

tions, Market-Specific

Caution

♦ After every repair on the passenger seat in which the seat

cover, for example, was “replaced”, a basic setting for the

Passenger Occupant Detection System Control Module -

J706- must be performed using the Vehicle Diagnostic

Tester .

♦ Passenger occupant detection system must not come in

contact with grease.

♦ There is the danger that the passenger occupant detection

system components may be damaged by sharp objects

when working on the seat. It is necessary to avoid this

danger.

♦ Make sure the seat cushion and the seat cover are instal‐

led correctly.

♦ Replace all upholstery clips. Make sure the seat cushion

is positioned correctly.

♦ Basic setting of the system is only possible between tem‐

peratures of 0 ℃ and +40 ℃ (32° and 104 °F).

♦ Make sure that no objects are placed on seat when per‐

forming basic setting.

♦ Using a seat cover or placing a cushion on the seat will

impair the passenger occupant detection system as well

as the effectiveness of the airbag system.

1.8

Restraint System Pyrotechnical, Electric

and Mechanical Components, Replac‐

ing After a Collision

Special tools and workshop equipment required
♦ Vehicle Diagnostic Tester

Note

♦

The airbag control module can be used for up to two deploy‐

ments of the side airbag and/or belt tensioner with airbag

generation 8.* »not 8.R«.

♦

The airbag control module can be used for up to two side,

driver and front passenger airbag and/or belt tensioner de‐

ployments with airbag generation 9.*, 10.* and 8.R.

♦

After the third deployment, the malfunction indicator “Control

module faulty” appears.

The Airbag Control Module Must Be Replaced:
♦ With driver and passenger airbag deployment “but not with

airbag generation 9.*, 10.* and 8.R”. Refer to 

⇒ page 9

♦ After three side, driver, and passenger airbag or belt tensioner

deployments

♦ If housing is damaged

♦ If there is deformation on tunnel in 200 mm circumference

around control module

Always Replace the Following:
♦ All deployed airbag units
Also with Front Passenger Airbag Deployment:
♦ Instrument Panel
♦ Deformed supports of the front passenger airbag unit (cannot

be reformed).

♦ All sensors for front airbag on front end
♦ Remaining transverse acceleration sensors if the mounting

points are deformed in the sensor area

Also with Driver Airbag Deployment:
♦ Return Spring with Slip Ring
♦ All sensors for front airbag on front end
♦ Remaining transverse acceleration sensors if the mounting

points are deformed in the sensor area

Also with Side Airbag Deployment:
♦ Pressure sensors on the deployed side
♦ Transverse acceleration sensors on the deployed side
♦ Cover
♦ Cushion
♦ With a folding rear seat backrest: side cushion (if equipped)
♦ Remaining transverse acceleration sensors if the mounting

points are deformed in the sensor area

Also with Passenger Occupant Detection System
♦ Each time the front passenger airbag and/or belt tensioner on

the front passenger side is deployed, the Passenger Occupant

Detection System Control Module - J706- basic setting must

be performed using the Vehicle Diagnostic Tester .

♦ If the seat rail and/or the seat pan need are replaced due to

deformations, then a basic setting must be done on the Pas‐

senger Occupant Detection System Control Module - J706-

using the Vehicle Diagnostic Tester Vehicle Diagnostic

Tester .

Also:
♦ All automatic belt retractors with deployed belt tensioners.
♦ All automatic belt retractors with deployed seat belt force lim‐

iters (depending on vehicle equipment).

♦ Seat belt latches for all automatic belt retractors with deployed

seat belt tensioners with the belt on

♦ Seat belt height adjuster (manual and power) for all automatic

belt retractors with deployed seat belt tensioners with the belt

on

– Connect the Vehicle Diagnostic Tester if there is a chance the

belt tensioner and/or seat belt force limiter deployed.

– In »Guided Fault Finding« under “15 - Airbag”, check whether

there is a crash entry in the airbag control module.

– Also check if the “Resistance too large” error is stored for the

belt tensioner and/or belt force limiter. Deployed belt tension‐

ers and/or belt force limiters must fulfill both conditions. “Re‐

quirement: the airbag control module was not replaced yet”.

Note

♦

The “Resistance too large” error may also be stored if there is

an open circuit. Then there is normally no crash entry.

♦

Depending on the crash, the belt tensioner may have deployed

while the belt force limiter did »NOT«. Follow the disposal in‐

formation for pyrotechnic components. Refer to

⇒ “1.3 Airbag, Belt Tensioner and Battery Cut-Out Units, Stor‐

ing, Transporting and Disposing (Pyrotechnic Components)”,

page 5

 .

♦

Also check the seat belts. Refer to

⇒ “1.11 Seat Belts, Checking”, page 12

 .

♦

Deployed seat belt force limiters can be recognized by the fol‐

lowing characteristics:

♦

The pin -1- and tab -3- are protruding out of the belt force lim‐

iter housing on the automatic belt retractor.

♦

The tab -2- is no longer vertical but is diagonal toward the out‐

side.

– If parts of the seat belt system are removed due to an accident,

replace the belt system bolts.

– If needed (visual inspection), the following must also be re‐

placed: all faulty components.

– After replacing the airbag units or the control module, affix

stickers (only tear-off strips) to the registration card and return

the registration card to the relevant Sales Center or to the Im‐

porter for registration.

1.9

Airbag Fasteners, Checking After a Col‐

lision

All Damaged Fastening Elements Must Always Be Replaced. Re‐

shaping the Components or »Making Them Fit« Is Not Permitted.
The following components must be checked after every airbag

deployment.
With a Front Passenger Airbag Deployment:
♦ Instrument panel central tube, front passenger airbag supports

and passenger airbag unit must be installed free of tension.

Replace the central tube.

♦ Check the glove compartment for damage. Replace the glove

compartment if damaged.

With a Driver Airbag Deployment:
♦ Steering wheel: Remove the steering wheel and place it with

the rim on a flat surface. The entire steering wheel rim must

rest on the surface. Otherwise the steering wheel should be

replaced.

♦ Check steering wheel for smoke residue. If smoke residue is

present, replace the steering wheel.

1.10

Collision without Airbag Deployment

♦ If the Airbag Indicator Lamp - K75- does not indicate a mal‐

function, then it is not necessary to replace the pyrotechnic

components. Seat belts must be checked separately.
