   Chassis > DRS > Trouble Codes 

   Result

   Result	Proceed to
   DTCs C1B04 or C1B05 is output	A
   DTCs other than C1B04 and C1B05 are output	B
   DTC is not output	C

Result: 

B 

REPAIR CIRCUITS INDICATED BY OUTPUT DTCS. Refer to  DIAGNOSTIC TROUBLE CODE CHART [12/2017 - 10/2023] 

Result: 

C 

USE SIMULATION METHOD TO CHECK. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [12/2017 - 09/2018]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [09/2018 - 10/2020]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [10/2020 - 11/2021]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [11/2021 - 10/2022]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [10/2022 - 10/2023] 

Result: 

A 

See step  2

1. Perform actuator calibration value initialization.

   Refer to CALIBRATION [12/2017 - 10/2023]

See step  4

1. Check the rear wheel alignment and make adjustments if necessary.

   Refer to ADJUSTMENT [12/2017 - 09/2018] , or refer to ADJUSTMENT [09/2018 - 10/2020] , or refer to ADJUSTMENT [10/2020 - 10/2022] , or refer to ADJUSTMENT [10/2022 - 10/2023]

   NOTE:

   After adjusting the rear wheel alignment, perform front wheel alignment adjustment.

Result: 

NEXT 

See step  5

1. Check for DTCs.

   Refer to DTC CHECK / CLEAR [12/2017 - 10/2023]

   Chassis > DRS > Trouble Codes 

   NOTE:

   If DTC C1B04 or C1B05 is output after performing neutral position memorization and motor rotation angle sensor calibration, confirm that the procedures are being performed correctly and perform neutral position memorization and motor rotation angle sensor calibration again (the maximum amount of attempts to perform neutral position memorization and motor rotation angle sensor calibration is 3 times).

   Result

   Result	Proceed to
   DTC is not output	A
   Even after performing neutral position memorization and motor rotation angle sensor calibration 3 times, DTC C1B04 or C1B05 is output.	B

Result: 

A 

END 

Result: 

B 

REPLACE REAR STEERING LINK ASSEMBLY. Refer to  REMOVAL [12/2017 - 09/2018]  , or refer to  REMOVAL [09/2018 - 10/2020]  , or refer to  REMOVAL [10/2020 - 10/2022]  , or refer to  REMOVAL [10/2022 - 10/2023]
