ECU IDENTIFICATION
ITS control unit part number is displayed.
In general, each customer feels differently about an incident. It is important to fully understand the symptoms or conditions for a customer complaint.
There are many operating conditions that lead to the malfunction. A good grasp of such conditions can make troubleshooting faster and more accurate.
Some conditions may cause the lane departure warning lamp to stay ON.
Utilize a work sheet sample to organize all of the information for troubleshooting.
KEY POINTS

- WHEN..... Date, Frequencies
- WHERE..... Road conditions
- HOW..... Operating conditions, Symptoms
Scheme 2
- Perform action test to verify the customer's concern.
- Perform action test and check the system operation after system diagnosis.
| WARNING | Be careful of traffic conditions and safety around the vehicle when performing road test. |
| CAUTION | Fully understand the following items well before the road test; Precautions: Refer to " PRECAUTION FOR LDW SYSTEM SERVICE ". System description for LDW: Refer to " SYSTEM DESCRIPTION ". System description for BSW: Refer to " SYSTEM DESCRIPTION ". System description for MOD: Refer to " SYSTEM DESCRIPTION ". Handling precaution: Refer to " PRECAUTIONS FOR LANE DEPARTURE WARNING ". |
Always perform the calibration after removing and installing or replacing the rear view camera.
| CAUTION | The system does not operate normally unless the rear view camera aiming adjustment is performed. Always perform it. |
Always perform the calibration after removing and installing or replacing the rear view camera.
| CAUTION | Place the vehicle on level ground when the calibration is performed. Follow the CONSULT when performing the calibration. (Rear view camera calibration cannot be operated without CONSULT). |
Scheme 3
- PERFORM SELF-DIAGNOSIS Perform self-diagnosis of the ITS control unit. Is any DTC detected? Except "U1308" >> Perform diagnosis on the detected DTC and repair or replace the applicable item. Refer to " «DTC INDEX»(ref-576064-S14761827702013090900000) ". "U1308" or no DTC >> GO TO 2.
- PREPARATION BEFORE REAR VIEW CAMERA CALIBRATION NOTE: Select the "AVM" to diagnose the ITS control unit by CONSULT. Perform pre-inspection for diagnosis. Refer to " «INSPECTION PROCEDURE»(ref-576064-S15773353942013090900000) ". Adjust the tire pressure to the specified pressure value. Maintain no-load in vehicle. Check if coolant and engine oil are filled up to correct level and fuel tank is full. Situate vehicle where the camera is exposed at an atmosphere temperature between 0°C (32°F) and 30°C (86°F) Move the shift selector to P (Park) and release the parking brake. Clean the rear view camera. >> GO TO 3.
- PREPARATION OF CALIBRATION TARGET MARK Prepare the calibration target mark according to the following figure: Left and right targets Center target Side of the black or white area = 200 mm (7.87 in) Side of the square target = 400 mm (15.75 in) >> Refer to " «WORK PROCEDURE (TARGET SETTING)»(ref-576064-S36280132332013090900000) ".
CAN controller controls the communication of CAN communication signal and ITS communication signal, and the error detection.
