## NHTSA's summary

ECM Reprogram Dealer Inventory This bulletin applies only to vehicles equipped with 1.6L engine \(SR and NISMO trim levels\). \*\*\*\*\*Dealer Announcement\*\*\*\*\* Nissan is conducting a quality action to update the Engine Control Module \(ECM\) software to prevent permanent storage of a DTC as a result of a Multiway Control Valve \(MCV\) malfunction on 1,013 specific 2018 Nissan Sentra \(B17\) SR and NISMO vehicles equipped with the MR16DDT engine. If a MCV malfunction occurred and was repaired, the current ECM logic will allow a technician to reset the Malfunction Indicator Lamp \(MIL\), but the DTC will remain stored in ECM memory. Resulting in Inspection/Maintenance \(I/M; a.k.a. smog test\) failure when a DTC check is performed at an inspection station. Affected vehicles are not subject to stop sale and are either currently in dealer inventory or assigned and in transit to the dealer. In the interest of customer satisfaction, Nissan requests dealers to update the ECM software on the affected vehicles prior to retail sale. \*\*\*\*\*What Dealers Should Do\*\*\*\*\* 1. Verify if vehicles currently in new dealer inventory are affected by this quality action using Service Comm or DBS National Service History ? Open Campaign I.D. P8307 \- New vehicles in dealer inventory can also be identified using DBS \(Sales\-\> Vehicle Inventory, and filter by Open Campaign\). \- Refer to NPSB 15\-460 for additional information \- Please continue to check newly arriving inventory for campaign applicability. 2. Use the attached procedure to remedy vehicles affected by this quality action. 3. The service department should submit the applicable warranty claim for the action\(s\) performed so it can be closed on Service Comm and release the vehicle.
