Recirculation Control Motor Test
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. However, it is still accessible from the selected car via links, so may be relevant.
Special Tools Required
Backprobe Set 07SAZ-001000A (2)
NOTE:
Before testing the motor, check for climate control 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, and stop at Fresh. If it does not, reverse the connections; the recirculation control motor should run, and stop at Recirculate. 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.
- Measure the resistance between terminals No. 1 and No. 3 of the recirculation control motor. It should be between 4.2 and 7.8 kΩ.
- Reconnect the recirculation control motor 7P connector, then turn the ignition switch to ON (II).
- Using the backprobe set (07SAZ-001000A), measure the voltage between terminals No. 2 and No. 3 of the 7P connector.
Fresh: About 1.0 V
Recirculate: About 4.0 V
- If either the resistance or the voltage readings are not as specified, replace the recirculation control motor (see RECIRCULATION CONTROL MOTOR REPLACEMENT ).
