CUSTOMER SATISFACTION PROGRAM
SUBJECT:

Seat Mounted Side Impact Airbag Connector

MODELS:

2014 Chevrolet Silverado 1500
2014 GMC Sierra 1500

CONDITION
Certain 2014 model year Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles have driver
and passenger seat side impact airbag (SIAB) wiring harness connectors that may have high
resistance. The vehicle sensing and diagnostic module (SDM) interprets the high resistance as a
fault. A fault will illuminate the airbag readiness light and turn on a “SERVICE AIR BAG” driver
information center (DIC) message. The fault and the warning indicators may be intermittent.
Depending on the level of resistance, the SIABs may not deploy in a crash.
CORRECTION
Remove the driver and passenger SIAB wiring harness connectors and install electrical jumper
wires in their place.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in GM Global Warranty Management system. Dealership service personnel
should always check this site to confirm vehicle involvement prior to beginning any required
inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not
all similar vehicles may be involved regardless of description or option content.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle
identification number, customer name, and address information has been prepared and will be
provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent
directly to export dealers. Dealers will not have a report available if they have no involved vehicles
currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration
Records. The use of such motor vehicle registration data for any purpose other than follow-up
necessary to complete this program is a violation of law in several states/provinces/countries.

July 2014

Bulletin No.: 14166

Note: Perform the procedure in this bulletin on BOTH the front driver and passenger seat. The
SIAB connectors are located under the seat cushion, and the technician may find a single
SIAB connector or may find a second connector with power seat circuits next to it. On the
driver side it is a GREEN connector on the outboard side of the seat; on the passenger
side it is a GREY connector on the inboard side of the seat.

3957349
1. Starting on the passenger seat, locate the inboard grey SIAB harness connector (1) on
the underside of the seat cushion.

3957351
2. Gently pry the connectors from the seat matt.
3. Carefully remove approximately 76 mm (3 in) of conduit and tape from each side of the
connector to gain access to the wires.

3957356
4. As shown on the passenger side connector above, cut the wires from the harness
connector as close to the connector housing as possible to minimize wire length loss.

3957359
5. Strip off approximately 13 mm (1/2 in) of insulation from the wiring ends.

3957362
Note: Only use heat shrink tube, P/N 12355010, or an equivalent flexible adhesivelined/moisture resistant heat shrink tube to perform the repair in this bulletin.
6. Add one approximate 38 mm (1.5 in) section of heat shrink tube (3) to each of the four
wires.

Page 6

Bulletin No.: 14166

Important: .500 mm (20 gauge) wire is recommended as the jumper in order to help
maintain the integrity of the splice crimp.
7. Add an approximate 102 mm (4.0 in) length jumper wire (2), obtained locally, to
reconnect each set of cut wires.
7.1 Strip off approximately 10mm (0.40 in) of insulation from each end of the jumper
wire.
7.2 Fold over one end of the jumper wire and position it together with the folded over
end of one the cut wires.
7.3 Crimp a splice clip (1) over the joined wires using Special Tool J-38125-8, nest F.
Verify the crimp quality.
7.4 Fold over the other end of the jumper wire and position it together with the folded
end of the remaining wire.
7.5 Crimp a splice clip (1) over the joined wires using Special Tool J-38125-8, nest F.
Verify the crimp quality.
8. Repeat step 7 on the second cut wire.

3957373
Caution: Keep the heat shrink tube above the splice when soldering the splice to ensure that
the heat shrink is not prematurely shrunk and closed down over the wire or splice area due to
the heat from the soldering iron.
Warning: DO NOT use soldering equipment that is battery or electric powered. These types of
soldering irons can induce voltage into the circuit, which may cause inflator module deployment
and/or damage to electrical components. Use only the EL-28125-5 Ultra Torch or another
butane fueled soldering iron when working on SIR circuits.
9. Solder all four crimp and splice clips using the Ultratorch, part number J-38125-5, or another
butane fueled soldering iron.

over the splice crimp and insulated wires.

3957377
11. Wrap woven polyester electrical tape (PET) or equivalent anti-abrasion tape or electrical
tape (1) around the spliced section of both wires.
Warning: Ensure yellow tape is wrapped around the splice section of the seat wire harness to
properly identify supplemental inflatable restraint (SIR) wiring. Failure to properly identify SIR
wiring could cause deployment of the SIR components, personal injury, or unnecessary SIR
system repairs.

COURTESY TRANSPORTATION – For US and Canada
The General Motors Courtesy Transportation program is intended to minimize customer
inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited
Warranties. The availability of courtesy transportation to customers whose vehicles are within the
warranty coverage period and involved in a product program is very important in maintaining
customer satisfaction. Dealers are to ensure that these customers understand that shuttle service
or some other form of courtesy transportation is available and will be provided at no charge.
Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy
Transportation guidelines.

Dear General Motors Customer:
We have learned that certain 2014 model year Chevrolet Silverado 1500 and GMC Sierra 1500
vehicles may have been built with driver and passenger seat side impact airbag (SIAB) wiring
harness connectors that may have high resistance. The vehicle sensing and diagnostic module
(SDM) interprets the high resistance as a fault. A fault will illuminate the airbag readiness light
and turn on a “SERVICE AIR BAG” driver information center (DIC) message. The fault and the
warning indicators may be intermittent. Depending on the level of resistance, the SIABs may not
deploy in a crash.
Your satisfaction with your GM vehicle is very important to us, so we are announcing a program
to prevent this condition or, if it has occurred, to fix it.
What We Will Do: Your GM dealer will remove the driver and passenger SIAB wiring harness
connectors and install electrical jumper wires in their place. This service will be performed for
you at no charge.
What You Should Do: To limit any possible inconvenience, we recommend that you contact
your dealer as soon as possible to schedule an appointment for this repair. By scheduling an
appointment, your dealer can ensure that the necessary parts will be available on your
scheduled appointment date.
If you have any questions or concerns that your dealer is unable to resolve, please contact the
appropriate Customer Assistance Center at the number listed below.
