Please discard all copies of bulletin 15169. THIS PROGRAM IS IN EFFECT UNTIL MARCH 31, 2017. CONDITION Certain 2015 model year Chevrolet City Express model vehicles may exhibit a condition in which the vehicle engine will crank but not start. A reversed wire in the engine EGI harness can lead to an ignition sneak circuit, which can prevent the engine control module from commanding a spark at start-up. During the crank / no start event, a Malfunction Indicator Lamp will be illuminated, and the vehicle will store the following code: U0100, U1000, and B2193. CORRECTION Dealers are to revise the engine EGI harness. 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. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.

Page 4 April 2015 Bulletin No.: 15169A 4100171 Note: There are four red wires in this wiring harness. Identifying the largest red and largest purple wires are critical to the procedure. Compare the wires to identify which wires are the largest. 8. Locate the largest gauge red (1) and purple (2) wires in the harness. 9. Once the wires are identified, cut the purple wire (1) approximately in the middle from the removed wires and cut the red wire (2) approximately 13 mm (0.50 inch) below the purple wire. 10.

Page 7 April 2015 Bulletin No.: 15169A COURTESY TRANSPORTATION 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. WARRANTY TRANSACTION INFORMATION Submit a transaction using the table below.

DEALER PROGRAM RESPONSIBILITY All unsold new vehicles in dealers’ possession and subject to this program must be held and inspected/repaired per the service procedure of this program bulletin before customers take possession of these vehicles. Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, through March 31, 2017. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the involved vehicle listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter. In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your facility for service through March 31, 2017, you must take the steps necessary to be sure the program correction has been made before selling or releasing the vehicle. 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 tools, equipment, 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 dealer for information on whether your vehicle may benefit from the information.
