Mode Control Motor Test

2011 Honda CR-V EX, 2.4 RE4, BZHASECTION Mode Control Motor Test

NOTE: Before testing the motor, check for HVAC DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).

Disconnect the 7P connector from the mode control motor.
NOTE: Incorrectly applying power and ground to the mode control motor will damage it. Follow the instructions carefully.
Connect battery power to the terminal No. 1 of the mode control motor, and ground the terminal No. 2; the mode control motor should run smoothly, and stop at Vent. If it doesn't, reverse the connections; the mode control motor should run smoothly, and stop at Defrost. When the mode control motor stops running, disconnect battery power immediately.

If the mode control motor did not run in step 2, remove it, then check the mode control linkage and doors for smooth movement.
- If the linkage and doors move smoothly, replace the mode control motor (see MODE CONTROL MOTOR REPLACEMENT ).
- If the linkage or doors stick or bind, repair them as needed.
- If the mode 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 mode control motor running as in step 2, check for continuity between terminal No. 7 and terminals No. 3, 4, 5, and 6 individually. There should be continuity for a moment at each terminal as the motor moves through its travel.
If there is no continuity for a moment at each terminal, replace the mode control motor (see MODE CONTROL MOTOR REPLACEMENT ).

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
