Engine Control Module (ECM) Reprogram
Voluntary Service Campaign
Dealer Announcement:
Nissan has reclassified the previously announced quality action (PM968) for new vehicle inventory as a Voluntary Service Campaign to reprogram the Engine Control Module (ECM) on 846 specific 2021 Versa (N18) vehicles equipped with Manual Transmission and identified in Service Comm. Due to a program logic concern, a malfunction indicator light (MIL) for the coolant temperature sensor may illuminate unnecessarily while the engine is warming up.
Affected vehicles are not subject to stop sale and are either currently in dealer inventory or assigned and in transit to the dealer.

1. Verify if vehicles are affected by this Voluntary Service Campaign using Service Comm or DBS National Service History – Open Campaigns I.D. PM970.
2. Dealers are requested to remedy any affected vehicles in dealer new or pre-owned inventory to ensure customer satisfaction.
• New vehicles in dealer inventory can also be identified using DBS (Sales-> Vehicle Inventory, and filter by Open Campaign).
 Refer to NPSB15-460 for additional information
3. Dealers should use NTB21-015 to correct any vehicles subject to this campaign.
4. Once repaired, dealers should submit the claim, using the claims coding provided, and release the vehicle.
