1. Measure the auxiliary battery voltage with the ignition switch off.

   Standard Voltage

   11 to 14 V

   If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding to the next step.

2. Check the fuses and relays.
3. Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

1. Using the Techstream, check if the CAN communication system is functioning normally.

   HINT: 

   Refer to CAN Bus Check in CAN Communication System.

   1. for HV Model:

      Refer to DIAGNOSIS SYSTEM [10/2018 - 10/2019] Refer to DIAGNOSIS SYSTEM [10/2019 - 08/2021] Refer to DIAGNOSIS SYSTEM [08/2021 - 07/2022]

   2. for Gasoline Model:

      Refer to DIAGNOSIS SYSTEM [10/2018 - 10/2019] Refer to DIAGNOSIS SYSTEM [10/2019 - 07/2022]

   OK

   CAN communication system is functioning normally.

See step  4

1. Using the Techstream, Check for DTCs.

   Chassis > Front Recognition Camera > Trouble Codes 

2. Make a note of the output DTCs.

   Result

   Result	Proceed to
   DTCs are not output	A
   DTC C1AA800 is output	B
   DTC other than C1AA800 is output	C

Result: 

B 

GO TO DTC CHART (C1AA8000). Refer to  DTC C1AA8-00: Front Recognition Camera Optical Axis Misalignment Malfunction [10/2018 - 07/2022] 

Result: 

C

Result: 

A 

See step  5

1. Using the Techstream, check for vehicle control history (RoB).

   Chassis > Front Recognition Camera > Utility 

   Tester Display
   Vehicle Control History (RoB)

2. 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
   Vehicle control history (RoB) X2015 or X201C is output	B

Result: 

B 

GO TO VEHICLE CONTROL HISTORY (X2015 or X201C). Refer to  VEHICLE CONTROL HISTORY [10/2018 - 07/2022] 

Result: 

A 

See step  6

1. Using the Techstream, clear the vehicle control history (RoB).

   Chassis > Front Recognition Camera > Utility 

   Tester Display
   Vehicle Control History (RoB)

2. Using the Techstream, check for vehicle control history (RoB).

   Chassis > Front Recognition Camera > Utility 

   Tester Display
   Vehicle Control History (RoB)

   Result

   Result	Proceed to
   Vehicle control history (RoB) is not output	A
   Vehicle control history (RoB) is output	B

Result: 

A 

GO TO SYMPTOM SIMULATION. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [10/2018 - ] 

Result: 

B 

GO TO VEHICLE CONTROL HISTORY. Refer to  VEHICLE CONTROL HISTORY [10/2018 - 07/2022] 

1. Using the Techstream, Clear the DTCs.

   Chassis > Front Recognition Camera > Clear DTCs 

2. 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.

   Refer to DIAGNOSTIC TROUBLE CODE CHART [10/2018 - 07/2022] 

3. Using the Techstream, check for DTCs.

   Chassis > Front Recognition Camera > Trouble Codes
