ELECTRONIC CONTROL MODULE (BCM) EXCHANGE PROGRAM

To ensure that replacement units are returned as soon as possible, ECM and BCM units are excluded from the normal 30-day parts retention policy. This policy and the exclusion for parts to be returned to a remanufacturing center presented in Section 1-7-4 of the current Cadillac Service Policies and Procedures Manual. ECM's and BCM's are to be returned to GMSPO Parts Distribution Centers weekly in accordance with Section IV (Parts Return) of the current GM Dealer 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. This will also result in earlier receipt of credit for the cores.

The two-part Dealer Core Information tag (yellow tag) is included with each remanufactured part. Please complete the tag by supplying the information requested. The sample provided in this bulletin will direct you with information to complete the tag. Refer to Figure 1.

The information supplied by the tag is very important to the Remanufacturing Center. It will assist them in assuring that an intermittent, time, or temperature failure noted on the tag is thoroughly checked and repaired. This information should also be obtained for Over The Counter (OTC) sales.

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.
