- To remove the control module, refer to Replacing ECC Control Module .
- To access/replace the recirculation damper motor, see Replacing Damper Motor Recirculation .
- To connect the breakout box, see Connection Of Breakout Box ECC .
- Voltage on cables should be less than 1 V or 2-4 V below battery voltage, depending on which direction the motor is turning in. When the damper motor is not activated the voltage should be approximately 0 V. For other values, see Signal Specification ECC .
