COMMENTS ON TROUBLE SYMPTOM
When the screen of rear view camera is not shown even if the selector or shift lever is "R" (Reverse) position, the rear view camera, the wiring harness, connectors, inside rear view mirror assembly, back up light switch [M/T] or transmission range switch [A/T] may be defective.
NOTE:
- If the indicator remains illuminated in a red color and the image is not displayed when the selector or the shift lever is turned to "R" (Reverse) position and "AUTO" button of inside rear view mirror assembly is pushed, the inside rear view mirror assembly has a problem.
- The inside rear view mirror assembly keeps the monitor non-displayed forcibly and illuminates the indicator when "AUTO" button is pressed and held for 12 seconds. Inside rear view mirror assembly stores the forced non-displayed state, it can be canceled by pushing "AUTO" button with the ignition switch "ON" position.
PROBABLE CAUSES
- The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector.
- Malfunction of the rear view camera
- Malfunction of the inside rear view mirror assembly
- Malfunction of the backup light switch [M/T] or transmission range switch [A/T]
