System Description

The rearview mirror with rearview camera display system consists of a rearview camera and an automatic dimming inside mirror with a built-in rearview camera display. When the transmission range switch is in R position, the rearview monitor is on, and the image from the rearview camera appears. Brightness of the rearview camera display changes automatically using the front-facing lux level sensor (A), rear-facing lux level sensor (B), and the control unit for the automatic dimming inside mirror. The rearview monitor mirror's brightness will gradually dim if it is operated for a long time. The rearview monitor turns off, when the automatic dimming off button (C) is pressed and the indicator (D) goes off, or the transmission range switch is in other than R position.

Note. The normal operating temperature range of rearview mirror with rearview camera display is -22°F to 176°F (-30°C to 80°C). Allow the inside temperature of the vehicle to stabilize within the normal operating range before testing.

  1. Turn the ignition switch to ON (II).
  2. Check the auto dimming inside mirror indicator (A). If the indicator flashes 2 times, and then turns on, there is a malfunction in the mirror. Replace it.
  3. Turn the ignition switch to LOCK (0).
  4. Remove the roof console (see «ROOF CONSOLE INPUT TEST/REPLACEMENT»(/acura/zdx/i-2009-2013/remont/interiorillumination-lights/#interior-lights) ).
  5. Disconnect the 12P connector (B) from the roof wire harness (C).
  6. Inspect the connector and socket terminals to be sure they are all making good contact. If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system. If the terminals look OK, go to step 7.
  7. Remove the tailgate lower trim panel (see «TRIM REMOVAL/INSTALLATION - TAILGATE AREA»(/acura/zdx/i-2009-2013/remont/exteriorinterior-trim/#interior-trim__trim-removalinstallation-tailgate-area) ).
  8. With the connector still disconnected, do the following input tests. NOTE: Make sure the connector is connected while testing terminals No. 5, No. 6, and No. 12. Make sure the connector is disconnected while testing terminals No. 1, No. 2, No. 3, No. 7, and No. 8. If any test indicates a problem, find and correct the cause, then recheck the system. If the input tests prove OK. Substitute and connect a known-good rearview camera and check the monitor image in reverse. If the symptom is gone, the rearview camera is faulty; replace it (see «REARVIEW CAMERA REMOVAL/INSTALLATION»(/acura/zdx/i-2009-2013/remont/entertainment-systems/#navigation-system__rearview-camera-removalinstallation) ). If the symptom is still present, the rearview mirror is faulty; replace it (see «REARVIEW MIRROR REPLACEMENT»(/acura/zdx/i-2009-2013/remont/mirrors/#mirrors) ).

An open or high resistance in the wire Check for continuity between terminal No. 2 and body ground: There should be no continuity. A short to ground in the wire 1 WHT Disconnect the rearview camera 12P connector Check for continuity between terminal No. 1 and rearview camera 12P connector terminal No. 9: There should be continuity. An open or high resistance in the wire Check for continuity between terminal No. 1 and body ground: There should be no continuity. A short to ground in the wire 7 GRY Disconnect the rearview camera 12P connector Check for continuity between terminal No. 7 and rearview camera 12P connector terminal No. 8: There should be continuity. An open or high resistance in the wire 12 BLK In all ignition switch positions Measure the voltage between terminal No. 12 and body ground: There should be less than 0.2 V.
