Airbag Controller Coding

Airbag Controller Coding Updated 3 Apr. 2008 Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own ris. As always! you should refer to a "actory Repair #anual for #anual  for your $ehicle% #ae sure to download and install the late latest st $ersion $er sion of & '() '() before  before performing this procedure and that you are using a *+, or *+,'A series /nterface. /nterface. The )uggested 'oding and #anual /nde will only wor with these professional-grade /nterfaces.  1hene$er airbags ha$e deployed and there is crash data stored! the airbag controller must be replaced. They ha$e an electro-mechanical switch that deploys the airbags! somewhat lie the hammer and trigger on a gun! it cannot be recoced and you should stay far away from any people or companies who claim to be able to reset a used airbag controller. This procedure details how to code a new Airbag )R)4 'ontroller after it has been installed in a $ehicle. ew Airbag 'ontrollers in many &15Audi $ehicles contain a )oft 'oding of all 6eros from the factory and must be coded once they ha$e been installed in the $ehicle. Any problems with airbags or igniters should be repaired before trying to install and code a new controller. These instructions apply to most &17s from the #59: ;olf5:etta5< onward and these instructions do =T apply to Audis! ecept for the '>5" A> and ?@.

Suggested Coding 1hen connected to an applicable Airbag controller with all 6eros in the )oft 'oding4 &'() can )uggest an appropriate 'oding $alue. This feature is a$ailable only when &'() is used with one of our rofessional ;rade interfaces. (isclaimerB 1e cannot guarantee that the coding which &'() may suggest will be correct! but there should be no harm in trying it. /f it7s not correct! the control module should simply refuse to accept it and the coding will remain at 00000.

/n the abo$e eample! you would enter a )oftware 'oding of 9232 then clic C(o /t%D. After you eit out of the Airbag 'ontroller then get bac into it! the )oft. 'oding field should show 9232. /f the eisting 1or)hop 'ode is all 6eros! you may need to enter a 1or)hop 'ode before the module will accept the new coding anything non-6ero lie 923E should wor for the 1or)hop 'ode.

Manual Index Entry /n cases where &'() would offer Airbag module coding suggestions but cannot determine the /nde automatically! &'() will gi$e you the ability to manually enter an /nde to get the suggested coding. To find the coding! you7ll need the complete part number for the new Airbag module! which can be found onB • • •

The in$oice5order form for the Airbag module preferred4. The bo which the new Airbag module came in. The labels on the Airbag module as shown below4B

/n the abo$e eample! note that on the upper right! it says /(+, C03D! this is =T the inde5color code% The /nde is shown immediately following the part number and consists of a slash 7574 followed by 3 characters. The last two characters are what7s needed! so if the /nde is 59>A! you would enter >A. /f the /nde was 509+! you would enter 9+. =n the label at the bottom! the part number is followed by a slash then the /nde5color code with a leading 6eroB 9'0-F0F->0E-" 509+ /n that case the /nde5color code is 09+ so the #anual /nde /nput you use is 9+! which you enter into the #anual /nde /nput field belowB

/n this eample eample! if the /nde is 9+ then &'() should gi$e you a )uggested 'oding of 92>93! which you would enter in the )oftware 'oding field. /n the abo$e eample! you would enter a )oftware 'oding of 92>93 then clic C(o /t%D. After you eit out of the Airbag 'ontroller then get bac into it! the )oft. 'oding field should show 92>93. /f the eisting 1or)hop 'ode is all 6eros! you may need to enter a 1or)hop 'ode before the module will accept the new coding - anything non-6ero lie 923E should wor for the 1or)hop 'ode.

Important Note: &1 parts departments ha$e recently been carrying and supplying to # customers the 0 /nde of Airbag controllers as a replacement for se$eral different /nde numbers. /f the $ehicle originally had a different /nde number such as 9+! then other components in the $ehicle lie crash sensors may need to be changed in order to mae the 0 /nde wor. The dealership should pro$ide information on any needed additional parts.
