BULLETIN
2015 Altima and 2014 Sentra OCS
Dealer Service Action
Reference: PC324, PM462
Date: December 15, 2014
Attention: Dealer Principal, Sales, Service & Parts Managers
***** Dealer Announcement *****
Nissan is conducting a Dealer Inventory Service Action to replace the Occupant Classification
System (OCS) Control Unit on 41 certain specific 2015 Nissan Altima and 2014 Sentra
vehicles currently in dealer inventory.
Due to a manufacturing issue at the OCS supplier that has since been corrected, a very
small population of some of the control modules may have been manufactured out of
specification. The OCS control module will need to be replaced in these vehicles to ensure
correct OCS operation.
***** What Dealer Should Do *****
To ensure customer satisfaction, dealers are asked to perform the following repair procedure
prior to sale. Once repaired, vehicles can be sold without further action.
1. Verify the subject vehicle is affected by this service Action using SERVICE COMM I.D.
 PC324 – 2015 Altima
 PM462 – 2014 Sentra
2. Locate the vehicle in inventory and perform the attached procedure.
3. File the warranty claim and release the vehicle for sale.
NOTE: Parts have already been sent to your dealership for this action. If replacement parts
are needed, order one of the following:
 98856-9HN0A (Altima)
 98856-9AM0A (Sentra)
***** Vehicle Identification – Dealer Inventory *****

Action can be identified through two methods:
