- CUSTOMER PROBLEM ANALYSIS
HINT:
- In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
- Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
- The following 5 items are important points for problem analysis:
What Vehicle model, system name When Date, time, occurrence frequency Where Road conditions Under what conditions? Driving conditions, weather conditions How did it happen? Problem symptoms

- PRE-CHECK
- Measure the battery voltage.
Standard voltage
11 to 14 V
HINT:
If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.
- Check the fuses and relays.
- Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

- Measure the battery voltage.
- CHECK COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM*
- Using the Techstream, check for CAN communication system DTCs.
Refer to DIAGNOSIS SYSTEM [10/2022 - 10/2023] , or refer to DIAGNOSIS SYSTEM [10/2023 - ]
Result
Result Proceed to CAN DTCs are not output A CAN DTCs are output B
Result:
B
GO TO CAN COMMUNICATION SYSTEM. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2018 - ]
Result:
A
See step 5
- Using the Techstream, check for CAN communication system DTCs.
- CHECK FOR DTC*
- Using the Techstream, check for DTCs.
Chassis > Front Recognition Camera > Trouble Codes
- If a DTC is output, record the DTC.
Result
Result Proceed to DTCs are not output A DTC C1AA8-00 is output B DTC other than C1AA8-00 is output C
Result:
A
See step 7
Result:
B
GO TO DIAGNOSTIC TROUBLE CODE CHART (C1AA8-00). Refer to DTC C1AA8-00: Front Recognition Camera Optical Axis Misalignment Malfunction [10/2022 - ]
Result:
C
See step 6
- Using the Techstream, check for DTCs.
- RECONFIRM DTC OUTPUT*
- Using the Techstream, clear the DTCs.
Chassis > Front Recognition Camera > Clear DTCs
- Reproduce the vehicle conditions that were present when the DTCs that were noted were stored.
HINT:
Refer to each corresponding DTC for details on the detection conditions.
- Using the Techstream, check for DTCs.
Chassis > Front Recognition Camera > Trouble Codes
Result
Result Proceed to DTCs are not output A DTCs are output B
Result:
B
GO TO DIAGNOSTIC TROUBLE CODE CHART. Refer to DIAGNOSTIC TROUBLE CODE CHART [10/2022 - ]
Result:
A
See step 7
- Using the Techstream, clear the DTCs.
- CHECK VEHICLE CONTROL HISTORY*
- Using the Techstream, check for Vehicle Control History (RoB).
Chassis > Front Recognition Camera > Utility
Tester Display Vehicle Control History (RoB) - Make a note of the output Vehicle Control History (RoB).
Result
Result Proceed to Vehicle Control History (RoB) is not output A Vehicle Control History (RoB) other than X2015 and X201C is output B Vehicle Control History (RoB) X2015 or X201C is output C
Result:
A
USE SIMULATION METHOD TO CHECK. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2022 - ]
Result:
C
GO TO VEHICLE CONTROL HISTORY (X2015 or X201C). Refer to VEHICLE CONTROL HISTORY [10/2022 - ]
Result:
B
See step 8
- Using the Techstream, check for Vehicle Control History (RoB).
- RECONFIRM VEHICLE CONTROL HISTORY*
- Using the Techstream, clear the Vehicle Control History (RoB).
Chassis > Front Recognition Camera > Utility
Tester Display Vehicle Control History (RoB) - Using the Techstream, check for Vehicle Control History (RoB).
Chassis > Front Recognition Camera > Utility
