air bag light on

[scotspie501]

Hi All

I have this question before ,my airbag light is on and i,ve tried vag com -lite and can connect with engine and various others abs etc
the only one I cant connect with is airbag

does this mean the module is faulty and requires a new one and can I buy one from e-bay as I have seen them for sale
or does it need to be programmed

its driving me crazy

Hi all

does anyone know the dc supplies and earth to check for the air bag module

I have a haynes manual but cant find it

even a drawing would be great

If the airbag light is on due to non communication you should get faults in other control units that you can read .
This may give you a clue if it is indeed a faulty control unit for air bag ?

Edit: it’s also a M.O.T failure

I dont think its a MOT failure
i,m trying to find out Dc connections for the airbag module

all other modules are good just cant connect to that module

I think your wrong there, see here as these cars don’t have the function to indicate the passenger air bag is turned off it just indicates a fault.

7.1.6. Supplementary restraint system (SRS)
The SRS MIL (Malfunction Indicator Lamp) should only be failed if it is indicating a system malfunction. A lamp illuminated to indicate the passenger airbag is disabled is not to be regarded as a defect.

Warning messages on dashboard displays are not a defect in their own right, but may assist the tester in determining that the warning lamp is illuminated because a malfunction exists.

Defect Category
(a) An SRS malfunction indicator lamp (MIL) indicates a system malfunction Major
