DTC C1A0A: Front Radar Sensor Region Code Mismatch [09/2014 - 10/2015]: Procedure

1. Use the Data List to check if the country specification information is correct (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015] ).
   RADAR CRUISE
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Country# (F Radar Sens)	Millimeter wave radar sensor country signal / JPN, NA, EURO, AUS, SAFC, OTHER, TWN, CHINA, THAI, GCC, NOFIX	Actual country code	-

   RESULT
   
   

   Result	Proceed to
   Country specification information for vehicle and front millimeter wave radar sensor match	A
   Country specification information for vehicle and front millimeter wave radar sensor do not match	B

   HINT: 

   The country specification information stored in the driving support ECU is determined by the country specification information stored in the main body ECU. If the country specification information for the millimeter wave radar sensor matches the vehicle, the country specification information for the main body ECU and driving support ECU is incorrect and the main body ECU and driving support ECU need to be replaced.

Result: 

B 

REPLACE MILLIMETER WAVE RADAR SENSOR ASSEMBLY 

(Refer to REMOVAL [09/2014 - 10/2015] )

Result: 

A 

See step  2

1. Clear the DTCs (Refer to DTC CHECK / CLEAR [09/2014 - 10/2015] ).
2. Check for DTCs (Refer to DTC CHECK / CLEAR [09/2014 - 10/2015] ).

   OK

   DTC C1A0A is not output.

   NOTE:

   When replacing the driving support ECU, always replace it with a new one and be sure to perform initialization (Refer to INITIALIZATION [09/2014 - 10/2015] ). If an ECU which was installed to another vehicle is used, the information stored in the ECU will not match the information from the vehicle, and as a result, a DTC may be stored.

Result: 

OK 

USE SIMULATION METHOD TO CHECK 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [09/2014 - 10/2015] )

Result: 

NG 

REPLACE DRIVING SUPPORT ECU 

(Refer to REMOVAL [09/2014 - 10/2015] )
