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 the terminal 3 and grounding terminal 4.
Verify that the auto defogging actuator operates to the close position when connecting in the reverse.
1. - 2. - 3. Open 4. Close | 5. Sensor ground 6. Feedback signal 7. Sensor (+ 5V) |
Connect the auto defogging actuator connector.
Turn the ignition switch ON.
Check the voltage between terminals 6 and 5.
Door position | Voltage (V) | Error detecting |
Defog OFF (Close) | 0.3 ± 0.15V | Low voltage :0.1V or less |
Defog ON (Open) | 4.7 ± 0.15V | High voltage :4.9V or more |
It will feedback current position of actuator to controls.
If the measured voltage is not specification, substitute with a known-good auto defogging actuator and check for proper operation.
If the problem is corrected, replace the auto defogging actuator.
Disconnect the negative (-) battery terminal.
Remove the crash pad.
(Refer to BD group – “Crash pad”)
Disconnect the connector (A) and then remove the auto defogging actuator (B) after loosening the mounting screws.
Install in the reverse order of removal.
