Honda 76400-SDA-A03 Mirror Assembly, Rearview (Day/Night)

Professional-grade scan tools enable simple and accurate troubleshooting because 2008 and later models feature both Multiple Integrated Control Unit (MICU) and Gauge Control Module (GCM). The MICU combined with GCM operate key vehicle aspects including door locks, power windows, ignition lock and security system alongside interior and exterior lighting elements and Daytime Running Lights system as well as horn, windshield wipers, heating/air conditioning system and power mirrors and hazard flasher system. Any examination related to system failure should be conducted exclusively by service departments within authorized dealerships or certified automotive repair facilities with proper qualifications. Likewise electric rear view mirrors incorporate two motor systems: horizontal and vertical. The power mirror switch delivers power to the mirrors when the ON position on the ignition key is active; operating switches for both mirrors while listening for motor operation should be performed. The drive mechanism could be damaged because while motors produce sounds there is no movement of glass. To diagnose the issue you should check the fuse since the mirrors produce no sound. Check the fuse if it passes inspection tests. Next step is removing the power mirror adjustment switch and verifying its continuity value. Check the ground connections to verify their proper connection and evaluate them for corrosion development. The inspection of the mirror wires should happen after removing the mirror to determine if voltage remains present. Inspect the circuit for opens and shorts whenever no voltage exists within the system. To evaluate the mirror performance use jumper wires on the off-vehicle setup along with tested voltage input. Follow with a new component if the mirror fails the test.

Driving a 2012 or older model requires first lowering the window, taking off the mirror trim cover, unplugging the electrical connector, and undoing four nuts. First remove the electrical connector from the mirror (if present), then take out the two retaining nuts and pull the mirror away from the vehicle, taking care to detach the clips and remove the trim ring around the gear shift. To remove the inside mirror, swivel the base 90 degrees, pull down on the mirror to release it from the bracket on the windshield, and if the support frame fell off, secure it again with a specialized mirror adhesive kit you can find at auto parts dealers, after cleaning the glass and thoroughly supporting the base during application, per the adhesive instructions.

Models from 2008 and later feature a Multiple Integrated Control Unit (MICU) and Gauge Control Module (GCM), which link several systems for straightforward and precise troubleshooting, requiring a professional-grade scan tool. The MICU or GCM controls various functions including door locks, power windows, ignition lock and security system, interior and exterior lights, Daytime Running Lights, horn, windshield wipers, heating/air conditioning, power mirrors, and hazard flasher system. For any malfunctions, it is advisable to have the vehicle diagnosed by a dealership service department or a qualified automotive repair facility. Most electric rear view mirrors utilize two motors for adjustments: one for vertical and one for horizontal movement. When adjusting the mirrors, the power mirror adjustment switch sends voltage to the respective side mirror. With the ignition key in the ON position (engine not running), operate the adjustment switch for both mirrors and listen for the sound of the electric motors. If the motors are audible but the mirror glass does not move, the issue lies within the drive mechanism. If there is no sound from the mirrors, check the fuse. If the fuse is intact, remove the power mirror adjustment switch and have its continuity checked by a qualified repair facility. Inspect the ground connections to ensure they are secure and free of corrosion. If the mirror remains non-functional, remove it and check for voltage at the mirror wires. If no voltage is detected in any switch position, examine the circuit between the mirror and the adjustment switch for faults. If voltage is present, test the mirror off the vehicle with jumper wires; if it fails this test, it should be replaced.

Start by removing the trim cover from the mirror base, then loosen the set screw and slide the mirror off the base mount.

no hardware is included with this. yes the dimming day mirror needs the harness which this part number is no dimming
