Q: How do you remove the ignition control module from Cadillac DeVille and DTS?
A: To remove the ignition control module from 2000 through 2003 models, start by removing the Ignition Coil assembly. Then, locate and remove the mounting screws of the ignition control module. Once the screws are removed, carefully take out the control module. To install the module back, simply follow the reverse order of the removal steps.
