Honda Accord: Mode Control Motor Test
'08-09 models with A/T and '10 model with A/T
NOTE; Before testing the motor, check for HVAC DTCs (see page 21-9).
1. Disconnect the 7P connector from the mode control motor.
Incorrectly applying power and ground to the mode control motor will damage it Follow the Instructions carefully.
2. Connect battery power to terminal No. 1 of the mode control motor, and ground terminal No. 2; the mode control motor should run smoothly, and stop at Defrost. If it doesn't, reverse the connections; the mode control motor should run smoothly, and stop at Vent. When the mode control motor stops running, disconnect battery power immediately.

3. 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 page 21-62).
• If the linkage or doors stick or bind, repair them as needed.
• If the mode control motor runs smoothly, go to step 4.
4. Use a digital multimeter with an output of 1 mA or less at the 20 kQ 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 No. 6 individually. There should be continuity for a moment at each terminal as the motor moves through its travel.
5. If there is no continuity for a moment at each terminal, replace the mode control motor (see page 21-62).

• If the linkage or door sticks or binds, repair them as needed.
• If the mode control motor runs smoothly, go to step 4.
4. Measure the resistance between terminals No. 5 and No. 7s of the mode control motor. It should be between 4.2 and 7.8 kO.
5. Reconnect the mode control motor 7P connector, then turn the ignition switch to ON (II).
6. Using the backprobe set, measure the voltage between terminal No. 3 and No. 7 of the 7P connector.
Vent: About 0.5 V
Defrost: About 4.5 V
7. If either the resistance or the voltage readings are not as specified, replace the mode control motor (see page 21-62).
