Function Test

2000 Honda Accord SE, 2.3 CG5, MAXASECTION Function Test
  1. Remove the driver's door panel (see DOOR PANEL REMOVAL/INSTALLATION -- COUPE ).
  2. Disconnect the 10P connector from the power mirror switch.

  3. Choose the appropriate test based on the symptom:
    • Both mirrors don't work, go to step 4.
    • Left mirror doesn't work, go to step  6 .
    • Right mirror doesn't work, go to step  7 .
    • Defogger doesn't work (Canada), go to step  8 .
    1. Both mirrors 
  4. Check for voltage between the No. 1 terminal and body ground with the ignition switch ON (II). There should be battery voltage.
    • If there is no battery voltage, check for.
      • blown No. 4 (7.5 A) fuse in the driver's under-dash fuse/relay box.
      • an open in the YEL/BLK wire.
    • If there is battery voltage, go to step 5.
  5. Check for continuity between the No. 2 terminal and body ground.

    There should be continuity.

    • If there is no continuity, check for:
      • an open in the BLK wire.
      • poor ground (G551).
    • If there is continuity, check both mirrors individually as described in the next column.
    1. Left mirror 
  6. Connect the No. 1 terminal to the No. 7 terminal, and the No. 4 (or No. 9) terminal to body ground with jumper wires. The left mirror should tilt down (or swing left) with the ignition switch ON (II).
    • If the mirror does not tilt down (or does not swing left), check for an open in the BLU/WHT (or BLU/ORN) wire between the left mirror and the 10P connector. If the wire is OK, check the left mirror actuator.
    • If the mirror neither tilts down nor swings left, repair the BLU/GRN wire.
    • If the mirror works properly, check the mirror switch.
    1. Right mirror 
  7. Connect the No. 1 terminal to the No. 8 terminal, and the No. 4 (or No. 10) terminal to body ground with jumper wires. The right mirror should tilt down (or swing left) with the ignition switch ON (II).
    • If the mirror does not tilt down (or does not swing left), check for an open in the BLU/WHT (or LT GRN) wire between the right mirror and the 10P connector. If the wire is OK, check the right mirror actuator.
    • If the mirror neither tilts down nor swings left, repair the YEL/WHT wire.
    • If the mirror works properly, check the mirror switch.
    1. Defogger (Canada) 
  8. Connect the No. 3 and No. 6 terminals with a jumper wire, and check for voltage between the No. 3 terminal and body ground. There should be battery voltage and both mirrors should warm up with the ignition switch ON (II).
    • If there is no voltage or neither warms up, check for:
      • an open in the YEL/BLK and ORN/WHT wires.
      • blown No. 4 (7.5 A) in the driver's under-dash fuse/relay box.
      • poor ground (G551, G581).
    • If only one fails to warm up, check its defogger.
    • If both fail to warm up, check the defogger switch.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • 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.
