Electronic Automatic Temperature Control (EATC) Module Cold Boot Process

ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC) MODULE COLD BOOT PROCESS

The purpose of the cold boot process is to allow the electronic automatic temperature control (EATC) module to reinitialize and calibrate the actuators. To carry out the cold boot process, follow the steps below.

1. Turn the ignition switch to the OFF position.
2. Disconnect the EATC module electrical connectors.
3. Wait one minute.
4. Connect the EATC module electrical connectors.
5. Turn the ignition switch to the ON position.
6. 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.
