Condition
In extremely rare cases, some customers may
comment that the air bag warning lamp is illuminated.
This condition may be intermittent and when checking
the vehicle for DTCs, the SDM may report B0083,
B0084, B0085, B0086, B0087 and/or B0088 with
symptom code 0F. The code will be stored in history
and may be repeated. The code probably will not be
current.

Cause
This condition may be caused by possible
electro-magnetic interference (EMI) in the Amarillo,
Texas area from external sources such as aviation
airspace traffic radar, creating erratic sensor
information to the SDM.

Correction
An updated software calibration has been released to
address this condition.
BEFORE beginning the programming/reprogramming
event, please refer to the Programming/
Reprogramming Checklist section in this bulletin.
1. Verify the battery voltage is more than 12 volts but
less than 16 volts before proceeding with
reprogramming. The battery must be fully charged
BEFORE reprogramming a control module.
2. During reprogramming, the battery voltage must
be maintained within the proper range of
12-15.5 volts. CONNECT the approved
Midtronics® PSC 550 Battery Maintainer (SPS
Programming Support Tool (EL-49642) to the
vehicle or the GR8 (EL50313) in the power
supply mode.
⇒ If the above recommended tools are not
available, DO NOT connect a battery charger to
the vehicle. CONNECT a fully charged 12V
jumper or booster pack that is disconnected
from the AC voltage supply.
Notice: It is essential that the TIS terminal, MDI,
Tech 2® and/or Scan Tool are updated with the
latest software available.
3. Verify that the devices being used are updated with
the latest available software version BEFORE
beginning the reprogramming event.
4. BEFORE beginning reprogramming you MUST
refer to Control Module References in SI for the
appropriate Programming and Setup procedures.

reprogramming, a secure service department
connection MUST be used. DO NOT use any
public WiFi connection from the customer lounge.
6. Reprogram the SDM using the Service
Programming System (SPS) with the latest
calibrations available on TIS2WEB. Refer to the
SPS procedures in SI.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
