Program Bulletin
Bulletin No.: 12026
Date: June 2012
CUSTOMER SATISFACTION PROGRAM
SUBJECT:
Front Seat Wiring Connector Corrosion
MODELS:
2011-2012 Chevrolet Caprice Police Vehicles
U.S. Vehicles
THIS PROGRAM IS IN EFFECT UNTIL JUNE 30, 2014.
CONDITION
Certain 2011 and 2012 model year Chevrolet Caprice police vehicles, equipped with vinyl
interior floors, may have a condition where the front seat wiring connectors may corrode. If
large amounts of water or snow accumulate in the front seat foot-wells and splashes rearward
under the front seats, it could enter the wiring connectors. If sufficient water enters the
connectors, corrosion and a short circuit could occur and cause the airbag light to illuminate.
CORRECTION
Dealers are to replace and relocate the connectors.
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 dealers through the GM GlobalConnect Recall Reports. 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. Accordingly, you are urged to limit the use of this report to the
follow-up necessary to complete this program.

WARNING: To avoid personal injury or part damage, review the information below.
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 a butane fueled soldering iron when working on SIR
circuits.
Ensure that the wire seals are distant from the crimp before applying solder. This will avoid
melting the seals.
When soldering, hold the iron tip on the underside of the terminal and allow solder to flow
through the crimp from the top.
2839910
10.6 Solder all terminals at the wire crimp.
2839918
10.7
Position the wire seal to the terminal and crimp the seal and insulation using
Service Tool J38125-6 Jaw #1.
