Recirculation Control Motor Test - Honda 2004 Odyssey Service Manual

Recirculation Control Motor Test

1. Disconnect the 7P connector from the recirculation
control motor.
Incorrectly applying power and ground to
the recirculation control motor will damage it.
Follow the instructions carefully.
2. Connect battery power to the No. 1 terminal of the
recirculation control motor, and ground the No. 5
or No. 7 terminals; the recirculation control motor
should run smoothly. To avoid damaging the
recirculation control motor, do not reverse power
and ground. Disconnect the No. 5 or No. 7
terminals from ground; the recirculation control
motor should stop at Fresh (when the No. 7
terminal is disconnected) or Recirculate (when the
No. 5 terminal is disconnected). Don't cycle the
recirculation control motor for a long time.

3. If the recirculation control motor did not run in step
2, remove it, then check the recirculation control
linkage and doors for smooth movement.
• If the linkage and doors move smoothly, replace
the recirculation control motor.
• If the linkage or doors stick or bind, repair them
as needed.
