Customer Question

Hi,im from Germany,bought a 2012 Tahoe in Fla. Now the Airbag code B080 appears.

B0080 for what is that code ,its not for the left side impact sensor(Thats B0085)
Expert:  Gary replied 1 year ago.

the B0080 is for the passenger set position sensor

this below needs to be followed to find the problem

most of these have been the wiring to the sensor or the sensor itself being bad

The seat position sensor is used to determine the proximity of a front driver or passenger seat position with respect to the frontal air bag. There are two states of seat position, forward and rearward. The seat position sensor interfaces with the inflatable restraint sensing and diagnostic module (SDM) and allows the SDM to disable stage 2 of the frontal air bag for a front seat that is forward of the forward/rearward point in seat track. The seat position sensor provides 2 current ranges, one range for the forward seat position and one for rearward seat position. When the SDM receives input from a seat position sensor that the seat is rearward, and the SDM will not disable stage 2 deployment. When the seat is forward, the SDM will disable stage 2 deployment. The SDM monitors the seat position sensor circuit and if a fault is detected, the SDM will set code B0079 or B0080 and disable stage 2 frontal deployment

  • Seat position sensor
  • SDM module
  • Seat position sensor wiring harness connector
  • SDM wiring harness connector
  1. Ignition OFF, disconnect the harness connector at the appropriate B88 seat position sensor.
  2. Test for less than 10 ohm between the low reference circuit terminal 1 and ground.

¤If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K36 SDM.

  1. Ignition ON, test for 4-9 V between the signal circuit terminal 2 and ground.

¤If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K36 SDM.

¤If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K36 SDM.

  1. If all circuits test normal, replace the B88 seat position sensor.

Thank you very much,but there´s a cable Box comming out of the car .The first one come from the car.And this wire diagramm i need, to bypass the seat system.
Expert:  Gary replied 1 year ago.

why do you need to bypass the seat system ?

Customer: replied 1 year ago.
I bought the car in July in Tampa Florida.It arrived here in Germany without airbags.So im buying the parts via GM or ebay to get it complete again.Here in germany you do not get them.But i have to go to a institute it is called TÜV.
They have to inspect the car before i get german papers for it.But the sign "airbag service" is on.
With this sign they won´t give me the german papers for it.Some parts already arrived,and some parts i have to wait.
But now my license plate expires end of September the one from the US.
Till then i need to get the car to the TÜV.Otherwise its not allowed to drive on the streets anymore.We already got the Driver airbag,the passenger airbag.The 2 seat belt retractor systems ,we got from a Tahoe here in germany.and the Head airbags were still inside.
Expert:  Gary replied 1 year ago.

there is no way to bypass these systems

it needs all the parts and correct wiring for the airbag service message to go out

Customer: replied 1 year ago.
Now Gary,i understand that you can´t or not allowed to help me with this.
But please don´t treat me like a stupid.
Expert:  Gary replied 1 year ago.

it is a fact you can not bypass these systems

good luck i will opt out of the question

the wire diagramm from the pulg,
Thank you
