Mode Control Motor Test
WARNING: This page is about a different car, the 2009 Honda S2000 and 2008 Honda S2000. However, it is still accessible from the selected car via links, so may be relevant.
- 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 No. 1 terminal of the mode control motor, and ground the No. 2 terminal; 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 does 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.
- 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 the No. 7 terminal and the No. 3, 4, 5, and 6 terminals individually. There should be continuity for a moment at each terminal as the motor moves past each switch terminal.
- If there is no continuity for a moment at each terminal, replace the mode control motor.
