| 17089 01 | 2018-08-20. Service bulletin. 17089-01 - Product Emissions Recall. Revised. This bulletin has been revised to add the requirement for an SPS warranty claim code to accompany warranty transaction submission, and to add notes to the service procedure. Please discard all copies of bulletin 17089. General Motors has decided to conduct a Voluntary Emission Recall certain 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. An earlier correction for this condition (Voluntary Emission Recall 15594) may, under certain driving conditions, inadvertently cause the vehicle Check Engine Indicator to illuminate.For vehicles that were not serviced under previous recall 15594, dealers are to replace the NOx position 1 sensor and reprogram the engine control module with a modified calibration, and initiate a Diesel Particulate Filter cleaning cycle. For vehicles previously serviced under recall 15594, dealers are to reprogram the engine control module with a modified calibration, and initiate a Diesel Particulate Filter cleaning cycle. Confirm status of recall 15594 following the instructions in the Warranty Information section. |
