- Turn the ignition switch OFF.
- Disconnect the auto defogging connector.
- Verify that the auto defogging actuator operates to the open position when connecting 12V to terminal 7 and grounding terminal 3. Verify that the auto defogging actuator operates to the close position when connected in reverse.
- Connect the auto defogging actuator connector.
- Turn the ignition switch ON.
- Check the voltage between terminals 6 and 5.VOLTAGE SPECIFICATIONS
Door position Voltage (V) Error detecting Defog OFF (Close) 0.55 ± 0.15V Low voltage: 0.1V or less Defog ON (Open) 4.55 ± 0.15V High voltage: 4.9V or more It will feedback the current position of the actuator to controls.
- If the measured voltage is not within specification, substitute with a known-good auto defogging actuator and check for proper operation.
- Replace the auto defogging actuator if it is proved that there is a problem with it.
