What does the b0084 service airbag message mean?
GM C and K series trucks are known for setting airbag trouble codes B0084 and B0085, which also may set a service airbag message. Here are some tips to diagnose and fix a B0084 or B0085 code. If you get any of these codes: B0083 00, B0084 00, B0085 00, B0086 00, B0087 00, B0088 00. • The front end sensor has been shorted to voltage, open.
What does the b0085 code on a GM car mean?
GM also uses crash sensors inside the front doors. These sensors detect air pressure change during a crash as the door is crushed. If the vehicle is used as a service or delivery vehicle, B0085 trouble codes are often traced to a break in the wiring in the hinge area where the wires flex.
What does trouble code b0071 b0081 mean?
Both codes relate to a problem in the Sensing and Diagnostics module. Don’t start replacing air bad components like the clock spring or the module. The problem is most likely the result of a defective seat belt tensioner sensor located in the passenger side seat belt buckle.
Where are the airbags located on a GM car?
GM uses a Sensing and Diagnostic Module (SDM) to monitor crash sensors, set trouble codes, illuminate the service airbag message and activate the airbags. The front end sensors (FES) (crash sensors) are located directly under the radiator, protected by a skid plate.

When does the trouble code b0081 set?
Code B0081 often sets when the SDM cannot communicate with the PPS module. Before condemning the PPS module, the circuit between the SDM and PPS should be checked. This can be done using a digital multimeter (DMM). In addition, the PPS module’s circuit should be checked for proper power and ground. In some cases, the PPS module may be the problem.

What does it mean when the SDM says b0081?
Code B0081 indicates the SDM has detected a problem with the PPS module. The SDM will default to disabling the passenger airbag when this code is set. Code B0081 is typically caused by one of the following: Sometimes B0081 can pop up intermittently. This is especially true if the code is a history code and not current.
What is the front bumper airbag sensor code?
This is on my 05 Sierra 1/2 ton crew. Managed to locate a scanner that will show airbag codes, and it appears to be one of the 2 front bumper sensors (which I believe are mounted on the rad supports). The code read “front end sensor 2 fault”

Where are airbag codes stored in a GMC?
Below you will find common airbag codes that can be stored in your airbag control module after your vehicle was in an accident.
