General Motors has decided to conduct a Voluntary Emission Recall involving certain 2014 and 2015
model year Chevrolet Cruze model vehicles equipped with a 2.0L (RPO LUZ) diesel engine. On some
vehicles, depending on driving habits, soot may build up on the engine’s NOx position 1 sensor and / or
oxygen sensor, causing the vehicle Check Engine Indicator to illuminate.
Dealers are to replace the NOx position 1 sensor and reprogram the engine control module with a
modified calibration.

1.

Remove the Nitrogen Oxides (NOx) sensor. Refer to Nitrogen Oxides Sensor Replacement - Position 1 in SI.

2.

Install a new NOx sensor. Refer to Nitrogen Oxides Sensor Replacement - Position 1 in SI.

Note: Carefully read and follow the instructions below.
 Do NOT attempt to order the calibration number from GM Customer Care and Aftersales. The calibration
numbers required for this service procedure are programmed into control modules via a Multiple Diagnostic
Interface (MDI) with the calibration update. If you cannot access the calibration, call the Techline Customer
Support Center and it will be provided.
 Do NOT program a control module unless directed to by a service procedure or a service bulletin. If the control
module is not properly configured with the correct calibration software, the control module will not control all of
the vehicle features properly.
 Ensure the programming tool is equipped with the latest software and is securely connected to the data link
connector. If there is an interruption during programming, programming failure or control module damage may
occur.
 Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will
interrupt programming. When required, install the EL-49642 SPS Programming Support Tool to maintain system
voltage. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage
supply. DO NOT connect a battery charger.
 Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights
(including daytime running lights), HVAC, radio, etc.
 During the programming procedure, follow the SPS prompts for the correct ignition switch position.
 Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M)
system status indicators to NO.
 Prior to programming, record the engine oil life percentage remaining.

personal injury or property damage from fire or burns, perform the following:


Do NOT connect any shop exhaust removal hoses to the vehicle tailpipe.



Park the vehicle outdoors and keep people, other vehicles, and combustible material away during this procedure.

Particulate Filter DPF Regeneration Enable in SI.

5.

Perform a fuel trim reset with a scan tool.

6.

With a scan tool, reset the Engine Oil Life Remaining back to the original percentage recorded before the control
module was replaced, if available.

FOR CALIFORNIA, CONNECTICUT, DELAWARE, MARYLAND, MASSACHUSETTS, MAINE, OREGON, VERMONT,
WASHINGTON VEHICLES ONLY AND IN THE EVENT OF AN EPA-ORDERED EMISSIONS RECALL: Install a Recall

Dealer Responsibility
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession
and subject to this recall must be held and inspected/repaired per the service procedure of this bulletin before customers
take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded,
released to auction, used for demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System
(CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting
an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified
for sale within the CPOIS system, or once again be used in the CTP program.
Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle,
or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer
information indicated on the dealer 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. Recall 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 recall enters your vehicle inventory, or is in your dealership for service in
the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing
the vehicle.
***THE FOLLOWING 2 PARAGRAPHS ARE NOT FOR CANADA OR EXPORT***
When a California emissions recall is completed by a GM dealer, the dealer must provide the vehicle owner a “Proof of
Correction Certificate” which the owner may need to present to the California Department Of Motor Vehicles (DMV) when
renewing their vehicle registration. Without this correction certificate, the owner may be unable to renew their vehicle
registration.
Additional Certificates can be obtained, at no charge, from the 1Store application in GlobalConnect. Request GM Item
Number 1825 when ordering.

Dealer Reports
For dealers with involved vehicles, a listing with involved vehicles has been prepared and will be provided to U.S. and
Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. 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 recall 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 recall.
Courtesy Transportation – For USA & Canada
Courtesy transportation is available for customers whose vehicles are involved in a product program and still within the
warranty coverage period. See General Motors Service Policies and Procedures Manual, Sections 1.4 and 6.1.10, for
courtesy transportation program details.
Customer Notification
USA & Canada - General Motors will notify customers of this recall on their vehicle (see copy of customer letter included
with this bulletin).
In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer
notification letter recommends that customers have their vehicles serviced as soon as possible. It also advises that failure
to do so could legally be determined to be lack of proper maintenance.
Export - Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor
Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.

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.

November 2016
This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
This notice is sent to inform you that General Motors is conducting a voluntary emission recall that includes your
vehicle.
Reason For This Recall: Depending on driving habits, soot may build up on the engine NOx position 1 sensor and / or
oxygen sensor causing the vehicle Check Engine Indicator to illuminate.
What Will Be Done: Your GM dealer will replace the NOx position 1 sensor, reprogram the Engine Control Module
with a modified calibration and initiate a Diesel Particulate Filter cleaning cycle. This service will be performed for you at
no charge.
How Long Will The Repair Take? Because of service scheduling requirements, it is likely that your dealer will need
your vehicle longer than the actual service correction time of approximately 90 minutes.
What You Should Do: Please contact your Chevrolet dealer as soon as possible to arrange a service date and to
assure parts availability. Instructions for making this correction have been sent to your dealer. Please ask your dealer
if you wish to know how much time will be needed to schedule, process, and repair your vehicle.
If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance
Center at the number listed below.

Emission Law Information: In order to ensure your full protection under the emission warranty made applicable to
your vehicle by state and federal law, and your right to participate in future recalls, it is recommended that you have
your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper
maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection if this recall is not
accomplished.

IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS
The California Air Resources Board (CARB) requires vehicle emission recalls be completed prior to California
registration renewal. Uncorrected emission recalls will result in the inability to renew your California vehicle registration.
At the time of emission recall completion, your California dealer will issue a "Proof of Correction Certificate". Keep this
certificate and, if required, present it to the Department of Motor Vehicles when renewing your California registration as
proof of recall completion.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued
satisfaction with our products.
