ECM, PCM & BCM UNIT EXCHANGE PROGRAM POLICIES

Subject: ELECTRONIC CONTROL MODULE (ECM), POWERTRAIN CONTROL MODULE (PCM), BODY CONTROL MODULE (BCM) EXCHANGE PROGRAM

Models Affected: ALL 1992 MODELS

To ensure that replacement units are returned as soon as possible, ECM, PCM and BCM units are excluded from the normal 30 day parts retention policy as stated in the current Pontiac Service Policies and Procedures Manual. ECMS, PCMs and BCMs are to be returned to GMSPO in accordance with section IV, Item H (Parts Return) of the current GMSPO Parts and Accessories Policies and Procedures Manual.

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

NEW GOVERNMENT REGULATIONS REQUIRE THE REPORTING OF EMISSION CONTROL PRODUCT CONCERNS. SOME OF THE INFORMATION REQUIRED COMES FROM THE TWO-PART PRODUCT RETURN TAG WHICH IS INCLUDED IN THE REMANUFACTURED ECM, PCM AND BCM CONTAINERS. See the example tags on the back of this bulletin (a new style tag will be phased in for 1992) . For each unit returned, all areas of the Product Return tag MUST be properly completed. In addition, a legible copy of the repair order must be sent in with the returned unit. It is very important to describe what led to the replacement of these units (items 10 and 11 on the tag) . If more space is needed than that given on the return tag, then include a separate sheet. This information will aid in the correct analysis of each unit and help Pontiac to comply with government regulations. 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.

IMPORTANT: Please review this bulletin with the appropriate personnel so that all replaced ECM, PCM and BCM units are returned promptly.

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.
