Driver's Air Mix 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
Back probe 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 driver's air mix control motor.NOTE: Incorrectly applying power and ground to the driver's air mix control motor will damage it. Follow the instructions carefully.
- Connect battery power to terminal No. 7 of the driver's air mix control motor, and ground terminal No. 6; the driver's air mix control motor should run, and stop at Max Hot. If it does not, reverse the connections; the driver's air mix control motor should run, and stop at Max Cool. When the driver's air mix control motor stops running, disconnect battery power immediately.
- If the driver's air mix control motor did not run in step 2, remove it, then check the driver's air mix control linkage and door for smooth movement.
- If the linkage and door move smoothly, replace the driver's air mix control motor (see DRIVER'S AIR MIX CONTROL MOTOR REPLACEMENT ).
- If the linkage or door sticks or binds, repair them as needed.
- If the driver's air mix 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 driver's air mix 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. 1 of the 7P connector.
Max Cool: About 0.5 V
Max Hot: About 4.5 V
- If either the resistance or the voltage readings are not as specified, replace the driver's air mix control motor (see DRIVER'S AIR MIX CONTROL MOTOR REPLACEMENT ).
