To ensure that replacement ECM units are returned as soon as possible, ECM units are excluded from the normal 30 day parts retention policy as presented in Section I, Part VII, of the current Oldsmobile Service Policies and Procedures Manual. ECM's are to be returned to WDDGM Parts Distribution Centers weekly in accordance with Section IV, Item G,9 of the current GM Dealer Parts and Accessories Policies and Procedures Manual.

Elimination of the 30 day retention period for ECM units will speed analysis and resolution of any reported malfunctions. It will also result in earlier receipt of credit for ECM cores.

A two-part Return Tag is included in the remanufactured ECM container. All areas of the tag are to be completed for all ECM's returned for repair. After completion of the tag, the extra copy is to be attached to the scrap copy of the repair order and retained for disposition by the Oldsmobile Zone Representative.

Please make sure all affected personnel review this bulletin so all replaced ECM units are promptly returned.
