Electronic Automatic Temperature Control (EATC) Module and Electronic Manual Temperature Control (EMTC) Module Cold Boot Process

The purpose of the cold boot process is to allow the DATC/EATC or EMTC 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 DATC/EATC or EMTC module electrical connectors.
3. Wait one minute.
4. Connect the DATC/EATC or EMTC module electrical connectors.
5. Turn the ignition switch to the ON position.
6. Select any position except OFF on the DATC/EATC or EMTC module.

The DATC/EATC or EMTC module will now initialize and calibrate the actuators. Calibration of the actuators will take approximately 30 minutes.
