CONDITION On some 2010-2011 model year Chevrolet Express and GMC Savana vehicles equipped with a 6.6L diesel engine (RPO LGH) and 2011 model year Chevrolet Silverado and GMC Sierra 2500/3500 series vehicles equipped with a 6.6L diesel engine (RPO LML/LGH), the nitrogen oxide (NOx) sensor may fail due to contamination between the terminals in the sensor and the wire interface. The contamination may cause the NOx sensor signal to become unstable and/or oscillate which may cause a malfunction indicator light to illuminate. SPECIAL COVERAGE ADJUSTMENT This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. Dealers are to replace the NOx sensor. The repairs will be made at no charge to the customer. For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after January 7, 2015 are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to January 7, 2015 must be submitted to the Service Contract provider. VEHICLES INVOLVED All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties section in GM Global Warranty Management system. Dealership service personnel should always Page 2 March 2015 Bulletin No.: 13386A 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. PART INFORMATION Parts required to complete this special coverage are to be obtained from General Motors Customer Care and Aftersales (GMCCA). Part Number Description Quantity/Vehicle 19256343 NOx Sensor Kit – Position 1 1 19256344 NOx Sensor Kit –Position 2 1 SERVICE PROCEDURE 1. Determine if the nitrogen oxide sensors in position 1 and position 2 require replacement by using the appropriate diagnostic information in SI.  If the nitrogen oxide sensors do NOT require replacement, no further action is required. Inform the customer that any additional diagnosis and repairs are not covered under this special coverage. 4000071 Note: If diagnosis indicates that only one nitrogen oxide sensor requires replacement, inspect the date code of the other nitrogen oxide sensor to determine if it requires replacement. The date code (1) is located on the back side of the NOx sensor module. The first six digits of the code represent the date code. Refer to the photograph. The example in the photograph has a date code of 131103xxxx, which indicates a November 03, 2013 date code. All NOx sensors with a date code prior to 120914xxxx (September 14, 2012) should be discarded and replaced with a new sensor.  If the nitrogen oxide sensors require replacement, proceed to step 2. 2. Remove the nitrogen oxide sensors in position 1 and 2. Refer to Nitrogen Oxide Sensor Replacement — Position 1 and Nitrogen Oxide Sensor Replacement — Position 2 in SI. 3. Install new nitrogen oxide sensors in position 1 and 2. Refer to Nitrogen Oxide Sensor Replacement — Position 1 and Nitrogen Oxide Sensor Replacement — Position 2 in SI.

CUSTOMER NOTIFICATION General Motors will notify customers of this special coverage on their vehicles (see copy of typical customer letter included with this bulletin – actual letter may vary slightly). 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/retailer for information on whether your vehicle may benefit from the information.
