Bulletin No.: Service Bulletin Date: 15-NA-010 January, 2020 INFORMATION Subject: Information for New Vehicles with Less than 1,000 Miles that May Not Pass California Smog Inspection or Smog Inspection in Other States Attention: Depending on the State, this testing is identified as Emissions Inspection, Smog Check, Smog Inspection or Smog Testing. Brand: Buick Cadillac Chevrolet GMC Model: GM Passenger Cars and Trucks Model Year: VIN: from to from to 2015 2020 — — Involved Region or Country United States Catalyst Break-In Period Information Notice: • The catalyst break-in period has been approved by the California Air Resources Board (CARB) but vehicles operating within the break-in period may still be subject to an inspection within California’s Smog Inspection Program. • The catalyst break-in period concern has been most prevalent in California because they have a Smog Inspection I/M Readiness Policy that allows only the Evaporative Monitor to not be ready on newer model year vehicles. This concern has occurred in other states and is expected to occur more frequently as other States adopt a similar Smog Inspection policy. Copyright 2020 General Motors LLC. All Rights Reserved. Engine: Transmission: Gasoline — Page 2 January, 2020 • When presenting a new vehicle for the California Smog Inspection or for a Smog Inspection in another State, some vehicles with less than 1,000 miles (1,609 km), may not report an Inspection/Maintenance System Check Monitor Complete Yes status as required to Pass the Smog Inspection. This may be caused by the engine control module (ECM) disabling some of the post catalyst oxygen sensor diagnostics until a preset catalyst break-in period (which varies by model and vehicle) has been completed. The post catalyst oxygen sensor diagnostics must report an Inspection/Maintenance System Yes (O2S/HO2S Monitor Complete — Yes) to the Smog Inspection test equipment, but cannot do so until after the preset calibrated catalyst break-in period has been completed. In order to complete this catalyst break-in period, advise the Customer to operate their vehicle using the New Vehicle Break-In procedure as outlined in their Owner Manual. • In some cases passing the Smog Inspection may be required for vehicle registration of brand new 50 State vehicles. This can happen in the following ways: – Any time a vehicle is sold, delivered or registered outside of the GM dealer network (i.e., a vehicle sold through a broker, drop shipped, or upfit and delivered through an upfitter) are among some of the possible examples meeting the California Registration definition for new vehicles delivered outside of the California Dealer network. – A new vehicle is purchased in another state and is temporarily registered in that state before being brought into California. ⇒ If this occurs, a Smog Inspection is required in California. However, the vehicle will not be ready for the Smog Inspection until after the catalyst break-in period has been completed. Customer Options to Resolve the Case of a New Vehicle Not Being Ready for the California Smog Inspection When the vehicle is not ready for the Smog Inspection, the customer has a few options to resolve the situation as follows: 1. Obtain a Temporary Operating Permit from the California Department of Motor Vehicles, which will allow the customer to drive the vehicle allowing in many cases for the problem to resolve itself. 2. The customer can work with a GM Dealer to make sure the catalyst break-in period has completed and the O2S/HO2S Monitor Complete has been set to Yes, which could take 700–1000 miles of vehicle operation. 3. In California, the customer can call 1-800-622-7733 to make an appointment with the California Bureau of Automotive Repair (BAR) Bulletin No.: 15-NA-010 Referee Scheduling Center in order to get a waiver from the Oxygen Sensor Monitor Complete requirement. In other states, for Smog Inspection/Emissions Testing requirements, refer to the various websites contained within this Bulletin in the section titled: Smog Inspection, Emissions Inspection Website Information. Service Procedure Notice: This is not a warranty repair. Verify that the vehicle owner has operated their vehicle for a minimum of 400 miles (644 km) using the New Vehicle Break-In procedure as outlined in the appropriate Owner Manual. New vehicles may not be able to complete the Inspection/Maintenance System Check for certain HO2S 2 diagnostics prior to 700 miles (1,127 km) and could require 1,000 miles (1,609 km) or more of catalyst break-in depending on driving conditions. Observe the following O2S/HO2S Monitors on the scan tool. They must set to Yes in order to Pass the Smog Inspection: • O2S/HO2S Monitor Complete • O2S/HO2S Monitor Complete This Ignition Cycle • O2S/HO2S Monitor Enabled • O2S/HO2S Monitor Enabled This Ignition Cycle Once the vehicle has reached 400 miles (644 km), perform the following: 1. When it is safe to do so, perform several deceleration maneuvers from a minimum speed of 45 mph (72 km/h) for at least 10 seconds. Repeat this maneuver 3 to 4 times. Stop the vehicle and turn the ignition OFF. Perform this complete Step three additional times. Note: Decelerate/coast with no or limited brake input. Moderate to heavy braking can cause downshifts and the Diagnostic test will abort. Note: Decelerate/coast for at least 10 seconds at 0% Throttle Pedal. 2. Use a scan tool to verify the O2S/HO2S Monitors have set to Yes. ⇒ If the O2S/HO2S Monitors have not set to Yes, then continue mileage accumulation and if possible repeat the verification every 100 miles (160 km). 3. Once a scan tool indicates that all O2S/HO2S Monitors are set to Yes, the vehicle is prepared for the Smog Inspection. Note: At the time this was written, the California Smog Inspection only allows the EVAP Readiness Monitor to not be set to Yes and still pass the Smog Inspection. ⇒ If Readiness Monitors other than the O2S/ HO2S Monitors are not set to Yes, refer to the Inspection/Maintenance Complete System Set Procedure in SI.

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
