Recirculation Control Motor Test
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Before testing, check for HVAC DTCs (see HOW TO CHECK FOR DTCS WITH THE HDS
).
- Disconnect the 7P connector from the recirculation control motor.NOTE: Incorrectly applying power and ground to the recirculation control motor will damage it. Follow the instructions carefully.
- Connect battery power to terminal No. 7 of the recirculation control motor, and ground terminal No. 6; the recirculation control motor should run smoothly, and stop at Recirculate. If it does not, reverse the connections; the recirculation control motor should run smoothly, and stop at Fresh. When the recirculation control motor stops running, disconnect battery power immediately.
- If the recirculation control motor did not run in step 2, remove it, then check the recirculation control linkage and door for smooth movement.
- If the linkage and door move smoothly, replace the recirculation control motor (see RECIRCULATION CONTROL MOTOR REPLACEMENT ).
- If the linkage or door sticks or binds, repair them as needed.
- If the recirculation control motor runs smoothly, go to step 4.
- Use a digital multimeter with an output of 1 mA or less at the 20 kΩ range. With the recirculation control motor running as in step 2, check for continuity between terminals No. 3, No. 4, and No. 5, and terminal No. 7 individually. There should be continuity for a moment at each terminal as the motor moves past the switch's terminal.
- If there is no continuity for a moment at each terminal, replace the recirculation control motor (see RECIRCULATION CONTROL MOTOR REPLACEMENT ).
