WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The purpose of the cold boot process is to allow the EATC module to reinitialize and calibrate the actuators. To carry out the cold boot process, follow the steps below.
- Turn the ignition switch to the OFF position.
- Disconnect the EATC module electrical connectors.
- Wait one minute.
- Connect the EATC module electrical connectors.
- Turn the ignition switch to the ON position.
- Select any position except OFF on the EATC module.
The EATC module will now initialize and calibrate the actuators. Calibration of the actuators will take approximately 30 minutes.
