Some customers may comment about 5 slow chimes,
with no obvious reason. If the customer would check
the PPS display, they would notice the passenger seat
belt indicator is illuminated. Dealers should be aware
that when certain conductive objects are placed on the
front passenger seat, the front passenger airbag
indicator may illuminate. The seat belt reminder light/
chime may also be activated. Examples of objects that
could enable the airbag include:
• Computers, Electronic Tablets
• Charging and Audio Cables
• Cell Phones
• Tech 2®
• Large Container of Liquid
• Groceries
An electronic device does not necessarily need to be
turned on to cause this condition.

Because this vehicle is equipped with low risk
passenger airbags, the PPS system is designed to turn
the airbag on for most front seat occupants and turn the
airbag off for small children in child seats. The system
works by detecting the capacitance of the object on the
seat, not the objects weight; and certain conductive
objects will enable the airbag. The passenger seat belt
reminder system is active when the passenger airbag
is on.
Additionally, for some larger electronic devices,
DTCs 5045 or B0074 0F may set in the PPS module
depending on the vehicle. If you remove the electronic
device from the front passenger seat, the DTC will go
into history (if DTC was set). If this happens, clear all
SDM and PPS DTCs. If the PPS DTCs is still current,
follow the service procedure in SI for that DTC. If the
DTCs do not return, no repair is needed (do not replace
any parts for this condition).
Note: Never rest the diagnostic scan tool or
components on the passenger front seat or touch the
passenger front seat while the diagnostic scan tool is in
contact with your body.

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.
