id0903l4018700

Description	REAR MOUNT CAMERA IMAGE NOT CLEAR/NO IMAGE ON SCREEN
	•  Navigation image is output, however, rear mount camera image is not output •  Poor reception from rear mount camera
POSSIBLE CAUSE	•  Effects of non-genuine, after-market electrical components •  Rear mount camera connector poor connection, pin damage •  Rear mount camera malfunction •  Car-navigation unit connector poor connection, pin damage •  Open or short circuit in vehicle wiring harness (R position signal) •  Open or short circuit in vehicle wiring harness (rear mount camera power supply) •  Car-navigation unit malfunction

Diagnostic Procedure

Note

•  The malfunction may be caused by a non-genuine, after-market electrical component. If a non-genuine, after-market electrical component has been installed and it cannot be determined whether the malfunction cause is due to the non-genuine, after-market electrical component or not, more time may be required to perform the malfunction diagnosis. (See FOREWORD [CAR-NAVIGATION SYSTEM (DISPLAY-INTEGRATED TYPE)].)

Step	Inspection		Action
1	VERIFY AFTER-MARKET ELECTRICAL COMPONENT INSTALLATION CONDITION •  Verify if a non-genuine, after-market electrical component is installed. •  Has a non-genuine, after-market electrical component been installed?	Yes	Go to the next step.
		No	Go to Step 3.
2	VERIFY IF MALFUNCTION CAUSE IS AFTER-MARKET ELECTRICAL COMPONENT INSTALLATION •  Disconnect the non-genuine, after-market electrical component connectors. •  Verify if the malfunction symptom recurs as stated by the customer. •  Does the malfunction recur?	Yes	Go to the next step.
		No	Explain to the customer that the malfunction occurred due to the after-market electrical component installation.
3	VERIFY REAR MOUNT CAMERA CONDITION •  Is the rear mount camera lens soiled by dust or dirt?	Yes	Clean the rear mount camera lens.
		No	Go to the next step.
4	VERIFY IF MALFUNCTION CAUSE IS REAR MOUNT CAMERA •  Are there any scratches or damage on the rear mount camera lens?	Yes	Replace the rear mount camera. (See REAR MOUNT CAMERA REMOVAL/INSTALLATION.)
		No	Go to the next step.
5	VERIFY IF MALFUNCTION CAUSE IS POOR CONNECTION OF REAR MOUNT CAMERA CONNECTOR •  Remove the rear mount camera. (See REAR MOUNT CAMERA REMOVAL/INSTALLATION.) •  Inspect the rear mount camera connector for connection condition. •  Disconnect the rear mount camera and inspect the rear mount camera connector and vehicle wiring harness connector for pin disconnection or deformity. •  Are the connectors and pins normal?	Yes	Go to the next step.
		No	If connector connection is poor: •  Connect the rear mount camera connector securely. If the pins and/or connector of the rear mount camera are malfunctioning: •  Replace the rear mount camera. (See REAR MOUNT CAMERA REMOVAL/INSTALLATION.) If the pins and/or connector of the vehicle wiring harness are malfunctioning: •  Repair or replace the malfunctioning location.
6	VERIFY IF MALFUNCTION CAUSE IS POOR CONNECTION OF CAR-NAVIGATION UNIT CONNECTOR •  Remove the car-navigation unit. (See CAR-NAVIGATION UNIT REMOVAL/INSTALLATION.) •  Inspect the car-navigation unit connection condition. •  Disconnect the car-navigation unit connector and inspect the car-navigation unit connector and vehicle wiring harness connector for pin disconnection or deformity. •  Are the connectors and pins normal?	Yes	Go to the next step.
		No	If connector connection is poor: •  Connect the car-navigation unit connector securely. If the pins and/or connector of the car-navigation unit are malfunctioning: •  Replace the car-navigation unit. (See CAR-NAVIGATION UNIT REMOVAL/INSTALLATION.) (See CAR-NAVIGATION UNIT DISASSEMBLY/ASSEMBLY.) If the pins and/or connector of the vehicle wiring harness are malfunctioning: •  Repair or replace the malfunctioning location.
7	VERIFY IF MALFUNCTION CAUSE IS POOR RECEPTION OF R POSITION SIGNAL •  Verify the R position signal voltage. •  Remove the car-navigation unit. (See CAR-NAVIGATION UNIT REMOVAL/INSTALLATION.) •  Switch the ignition ON. •  Shift to the R position. Caution •  When performing the following procedure, keep the brake pedal depressed so that the vehicle does not unexpectedly move and cause an accident. •  Measure the voltage between car-navigation connector terminal 2A (R position signal) and terminal 1A (ground). •  Is the battery positive voltage 12V?	Yes	Go to the next step.
		No	Inspect the applicable (R position signal) vehicle panel and repair or replace.
8	VERIFY IF MALFUNCTION CAUSE IS POOR RECEPTION OF POWER SUPPLY •  Switch the ignition OFF (LOCK). •  Remove the car-navigation unit. (See CAR-NAVIGATION UNIT REMOVAL/INSTALLATION.) •  Switch the ignition ON. •  Shift to the R position. Caution •  When performing the following procedure, keep the brake pedal depressed so that the vehicle does not unexpectedly move and cause an accident. •  Measure the voltage between car-navigation connector terminal 2G (rear mount camera power supply) and terminal 1A (ground). •  Is the voltage 6V?	Yes	Replace the car-navigation unit. (See CAR-NAVIGATION UNIT REMOVAL/INSTALLATION.) (See CAR-NAVIGATION UNIT DISASSEMBLY/ASSEMBLY.)
		No	Inspect the applicable (rear mount camera power supply) vehicle panel and repair or replace.
