1. INITIAL CHECK FUNCTION Turn the engine switch on (IG). After 2 seconds or more have passed, turn the clearance sonar main switch ON. Then check the buzzer sounding condition. Buzzer sounding: 1 +/-0.3 sec. HINT: If a malfunction is detected in the ultrasonic sensor circuits, the location of the malfunctioning sensor blinks on the display's vehicle graphic. However, after the sensor returns to normal, the display also returns to normal. When the engine switch is turned on (IG) while the clearance sonar main switch is ON, the buzzer will not sound.
2. MALFUNCTION OF MULTI-INFORMATION DISPLAY Ultrasonic sensor open circuit If there is an open circuit between the ultrasonic sensor and the ECU or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration. HINT: The example shows an open circuit in the No. 1 ultrasonic sensor (front left sensor). If a sensor has an open circuit, "Check Park Sonar System" is displayed. Refer to "open circuit in front sensor is displayed as a result or self-check" on the Problem Symptoms Table to inspect it. Ultrasonic sensor frozen If a sensor is covered with foreign matter, such as mud or snow, the affected sensor is displayed as shown in the illustration. HINT: The example shows that the No. 1 ultrasonic sensor (front sensors) is frozen. If "Clean Park Sonar" is displayed, cleaning the foreign matter from the sensor will return the sensor to normal.
3. MALFUNCTION OF MULTI-DISPLAY Ultrasonic sensor open circuit If there is an open circuit between the ultrasonic sensor and the ECU or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration. HINT: This example shows an open circuit in the No. 1 ultrasonic sensor (rear right sensor). If a sensor has an open circuit, refer to «PROBLEM SYMPTOMS TABLE»(ref-349762-S23428559732009120800000) "open circuit in rear sensor is displayed as a result of self-check" on the Problem Symptoms Table to inspect it. Ultrasonic sensor frozen If a sensor is covered with foreign matter, such as mud or snow, the affected sensor is displayed as shown in the illustration. HINT: The example shows that the ultrasonic sensor (front left sensor) is covered with foreign matter. If "Clean sonar" is displayed, cleaning the foreign matter from the sensor will return the sensor to normal.
4. DETECTION RANGE MEASUREMENT AND DISPLAY INSPECTION Detection range measurement CAUTION: Make sure the vehicle does not move by applying the parking brake firmly. Turn the engine switch on (IG). Move the shift lever to R position to check the front side sensors, rear center sensors and rear corner sensors. Move the shift lever to D, S and N position to check front side sensors, front corner sensors and front center sensors. Turn the clearance sonar main switch ON. Move a 60 mm (2.36 in.) pole near each sensor to measure its detection range. Front center sensors detection range Front corner sensors detection range Front side sensors detection range Rear center sensors detection range Rear corner sensors detection range NOTE: These detection ranges are applicable when positioning the 60 mm (2.36 in.) pole parallel or perpendicular to the ground. The ranges vary depending on the measuring method and type of obstacle (such as walls). When the ultrasonic sensors have detected an obstacle, check the multi-information display, multi-display and buzzer sounds with the clearance sonar main switch ON.

DTC CHECK/CLEAR

1. CHECK DTC Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical/Intuitive P/A/Trouble Codes. Check for DTCs.
2. CLEAR DTC Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical/Intuitive P/A/Trouble Codes. Clear the DTCs.

DATA LIST/ACTIVE TEST

1. DATA LIST HINT: Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time. NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical/(desired menu)/Data List. According to the display on the Techstream, read the Data List.

2. ACTIVE TEST HINT: Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical/(desired system)/Active Test. According to the display on the Techstream, perform the Active Test.
