Control module for the Cadillac DeVille/STS with the LD8 or L37 engine.

On February 16, 2004 we started the Engineering Investigation on the Electronic Powertrain Control Module for the Cadillac DeVille/STS with the LD8 or L37 engine.

Our findings have led us to a better understanding of the crank, no start complaint, the transmission solenoid code and the no communication issue in the module. Your continued cooperation with these Engineering Investigations helps us find issues that we have been unable to find any other way. Please share this information with your technicians.

The PCM part number being cancelled for the Cadillac DeVille/STS with the LD8 or L37 engine is PCM P/N 12587465.

I know you are all aware how hot the competition has become on the quality side of our business with the recent information released by J.D. Powers. With your continued cooperation these Engineering Investigations help us identify the causes of product concerns that will allow us to continue to make improvements in our products to become the world leader in building the best quality product in the market today.

As always, we appreciate your cooperation in these efforts.
