Rear Mode 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.
Special Tools Required
Backprobe Set 07SAZ-001000A
NOTE:
Before testing, check for HVAC DTCs (see HOW TO CHECK FOR DTCS WITH THE HDS
) or climate control DTCs (see HOW TO CHECK FOR DTCS WITH THE HDS
).
- Disconnect the 7P connector from the rear mode, control motor.NOTE: Incorrectly applying power and ground to the rear mode control motor will damage it. Follow the instructions carefully.
- Connect battery power to terminal No. 7 of the rear mode control motor, and ground terminal No. 6; the rear mode control motor should run, and stop at Heat. If it does not, reverse the connections; the mode control motor should run, and stop at Vent. When the mode control motor stops running, disconnect battery power immediately.
- If the rear mode control motor did not run in step 2, remove it, then check the rear mode control linkage and door for smooth movement.
- If the linkage and door move smoothly, replace the rear mode control motor (see REAR MODE CONTROL MOTOR REPLACEMENT ).
- If the linkage or door stick or bind, repair them as needed.
- If the rear mode control motor runs smoothly, go to step 4.
- Measure the resistance between terminals No. 1 and No. 3. It should be between 4.2 to 7.8 kΩ.
- Reconnect the rear mode control motor 7P connector, then turn the ignition switch to ON (II).
- Using the backprobe set, measure the voltage between terminals No. 3 and No. 5.
Vent: about 1.5 V
Heat: about 4.0 V
- If either the resistance or voltage readings are not as specified, replace the rear mode control motor (see REAR MODE CONTROL MOTOR REPLACEMENT ).
