* The radio presets: This is usually done through a specific button sequence on the radio itself. Check your owner's manual for the exact procedure.
* The trip odometer: This is often reset by holding down a specific button on the instrument cluster (dashboard). Again, consult your owner's manual.
* The PCM (Powertrain Control Module): This is the main computer controlling the engine and transmission. You can't "reset" this in the same way you would a PC. If you're having problems with the engine or transmission, you might need to have a mechanic clear trouble codes using a diagnostic tool. Simply disconnecting the battery for a short time (30 minutes or so) might clear some minor glitches, but this is not a guaranteed solution. It's not a "reset" in the typical sense, either.
* Other modules: The Escalade has other modules controlling things like the climate control, airbags, and body electronics. These typically require specialized diagnostic tools to reset.
To find the specific reset procedure you need:
1. Consult your owner's manual: This is the most reliable source for information specific to your vehicle.
2. Specify what you're trying to reset: Knowing what part of the car isn't working will help in determining which system needs attention. For example, "My radio presets are gone," or "My check engine light is on," will provide much more useful information.
Without knowing *what* you are trying to reset, it's impossible to give a precise answer.
