Volkswagen New Beetle. Manual - part 26

 

 

z

After servicing, check SRS warning light to verify system operation. See SYSTEM OPERATION 
CHECK 
.  

z

Always wear safety glasses when servicing or handling an air bag.  

z

DO NOT expose air bag module and clockspring to temperatures greater than 200°F (93°C).  

z

When placing a live air bag module on a bench or other surface, always face air bag module and trim 
cover up, away from surface. This will reduce motion of module if air bag accidentally deploys.  

z

After air bag deploys, air bag surface may contain deposits of sodium hydroxide, which irritates skin. 
Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up. Wash hands using mild 
soap and water. Follow correct clean-up and disposal procedures.  

z

Because of critical system operating requirements, DO NOT service any SRS components, including 
wiring harness. Repairs are only made by replacing defective component(s).  

z

DO NOT allow any electrical source near inflator on the back of air bag module.  

z

When carrying a live (undeployed) air bag module, trim cover must be pointed away from body to 
minimize injury in case of accidental air bag deployment.  

z

DO NOT probe a wire through insulator, as this will damage wire and eventually cause failure due to 
corrosion.  

z

If SRS is not fully functional for any reason, DO NOT drive vehicle until system is repaired and is fully 
functional. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system 
from operating normally. If SRS is not functional, park vehicle until repairs are made.  

DISABLING & ACTIVATING AIR BAG SYSTEM 

To disable system, turn ignition switch to LOCK position. Disconnect and isolate negative battery cable. Wait 
at least ONE MINUTE before servicing vehicle. To activate system, ensure ignition switch is in LOCK position 
and reconnect negative battery cable. Staying well away from air bag modules, turn ignition switch to ON 
position. Ensure AIR BAG indicator light operates properly, see SYSTEM OPERATION CHECK .  

NISSAN 

SYSTEM OPERATION CHECK 

Turn ignition on. AIR BAG warning light should come on for about 7 seconds and then go off, indicating SRS 
is okay. If AIR BAG warning light does not come on, service Supplemental Restraint System (SRS). If AIR 
BAG warning light stays on constantly, service SRS. If AIR BAG warning light comes on for about 7 seconds, 
goes off, then starts flashing, a fault code is set in memory.  

SERVICE PRECAUTIONS 

Observe these precautions when working with air bag systems: 

NOTE:

On vehicles equipped with seat belt pretensioner, the seat belt warning light 
should also come on for about 7 seconds and then go off (with seat belt 
fastened).

harnesses.  

z

Before discarding an air bag module or seat belt pretensioner (including scrapping a vehicle with air bag 
system), always deploy air bag(s) and seat belt pretensioners.  

z

Replace used mounting bolts with NEW mounting bolts.  

DISABLING & ACTIVATING AIR BAG SYSTEM 

To disable SRS, turn ignition off. Disconnect and shield BOTH battery cables. Wait at least 3 MINUTES before 
working on vehicle. To activate SRS, connect battery cables. Turn ignition on. Ensure AIR BAG indicator light 
operates as specified. See SYSTEM OPERATION CHECK .
