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 the current Pontiac 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 and Procedures Manual. Dealer Parts and Accessories POlicies

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 ECM Return Tag is included in the remanufactured ECM container. All areas of the tag are to be properly completed for ECM's returned for repair. In order to reduce the high number of NTF (no trouble found) ECM's it is important that all information relative to the ECM malfunction be completed on the tags (i.e. trouble code(s), etc.). 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 Pontiac Zone Representative.

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

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
