Bulletin No.: PIP5325 Date: Sep-2015 Subject: How to Identify Factory or Aftermarket CNG, LPG, Bi-Fuel Systems Models: 2016 Prior Passenger Cars And Light Duty Trucks Prior to working on Alternative Gaseous Fuel Systems The Vehicle Emission Control Information Label (VECI) is located under the hood or in the engine compartment Recommendation/Instructions Each alternative fuel vehicle will have 2 VECI labels. (both factory and aftermarket fuel systems) • 1-VECI label from General Motors. • 1-VECI label from the gaseous fuel system supplier. By using the engine RPO code as well as the VECI labels, you can confirm the vehicle has a factory installed alternative fuel system or who the manufacturer is of the aftermarket fuel system. STEP 1: Verify vehicle's RPO code states that it is a Gaseous Fuels Engine or uses a specific Gaseous Fuel System RPO code, in Global Warranty Management. IF YES: Continue with normal GM diagnostics in SI. IF NO: Vehicle has been modified with an aftermarket gaseous fuel system. Proceed to step 2. STEP 2: Locate VECI label of aftermarket fuel system in the engine compartment. A: Contact the manufacturer per the VECI label for all service center locations and possible warranty repairs. B: Some VECI labels may have a contact number listed. If a number was not provided, you may have to use the internet to locate Service Centers that are approved to Perform Warranty Repairs. Examples Of VECI Labels 1 Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. 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. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION 2
