Bulletin No.: 16-NA-193

This may be caused by a loose or improperly installed battery cable for circuit #40 at the
X50B auxiliary fuse box right above the underhood electrical center.

Correction
If you encounter a vehicle with the above concern,
complete the following steps:
1. View all DTC freeze frame data from each module
that set codes (ECM, HPCM, HPCM2, EBCM, etc.)
as this may be useful later by Technical Assistance
in diagnosing the vehicle.

Note: See photo above of a properly installed
terminal. Notice that the terminal tabs are located in the
proper recess of the fuse box.
3. If the connection above is properly seated and
torqued (torque requirement D15+/ 2 NM S13-17
NM) on the vehicle as pictured in the photo above,
check all the connections at the X50D fuse box
that is located on the side of the 12V battery.

2. Check the terminal and make sure that the terminal
is straight and the tabs are properly in the fuse box.
Above is a picture of a terminal that was improperly
installed.
Note: The tabs of the terminal are stuck on a plastic
boss of the fuse block which causes the nut to be tight
but the terminal is not flush in the fuse box, which
causes a poor connection with the bus bar in the
fuse box.

4. If no visible concerns are found with the X50D rear
fuse box on the 12V battery, or there is no visible
arcing on the X50B auxiliary fuse box, it is
important to follow normal diagnosis referring to SI.
Do not assume these diagnostic codes were set by
this condition if no visible evidence was found of an
intermittent connection. There may be other
causes for these DTCs.

GM bulletins are intended for use by professional technicians, NOT a "do-it-xourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide mformat1on 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.
