Hyundai C1702 Code is a variant coding error that can occur during initialization due to faulty HECU or replacement of EMS, T/M ECU. The error is indicated by a difference in pre-inputted and re-inputted variant code as well as the EEPROM not having a valid variant code. To better understand the cause and solution to this error, two service bulletins – 13-01-047 and 14-01-035 – have been provided by NHTSA to aid in the diagnosis and repair of the issue. In this article, I will discuss the causes and solutions to the Hyundai C1702 Code variant coding error in detail.
Causes and Solutions to Hyundai C1702 Code
| Cause | Solution |
|---|---|
| Faulty HECU | Replace HECU with new one |
| Replacement of EMS, T/M ECU | Re-input variant code |
| EEPROM not having a valid variant code | Replace EEPROM with new one |
| Difference between pre-inputted and re-inputted variant code | Check codes and input the correct one |
Hyundai C1702 Code is an error that occurs when there is no inputted valid variant code during initialization. It is a variant coding error that can be caused by a faulty HECU, replacement of EMS, T/M ECU, or the EEPROM not having a valid variant code. To diagnose the issue and find a solution, two service bulletins – 13-01-047 and 14-01-035 – have been released by NHTSA. The causes and solutions to this error include replacing the HECU with a new one, re-inputting the variant code, replacing the EEPROM with a new one, and checking codes and inputting the correct one. In this article, I will discuss the causes and solutions to the Hyundai C1702 Code variant coding error in detail.
Faulty HECU
One of the causes of the Hyundai C1702 Code is a faulty HECU. If the HECU is faulty, the best solution is to replace it with a new one. This will help to fix the issue and return the system to its normal functioning.
Replacement of EMS, T/M ECU
Another cause of the Hyundai C1702 Code is the replacement of EMS, T/M ECU. If this is the case, the solution is to re-input the variant code. This will help to ensure that the variant code is inputted correctly and that the system is functioning as expected.
EEPROM not having a valid variant code
If the EEPROM does not have a valid variant code, the solution is to replace it with a new one. This will help to ensure that the variant code is valid and that the system is running as expected.
Difference between pre-inputted and re-inputted variant code
The last cause of the Hyundai C1702 Code is the difference between pre-inputted and re-inputted variant code. If this is the case, the solution is to check the codes and input the correct one. This will help to ensure that the variant code is inputted correctly and that the system is functioning as expected.
Conclusion: Repairing the Hyundai C1702 Code Error
The Hyundai C1702 Code is a variant coding error that can occur during initialization due to faulty HECU or replacement of EMS, T/M ECU. To diagnose the issue and find a solution, two service bulletins – 13-01-047 and 14-01-035 – have been released by NHTSA. The causes and solutions to this error include replacing the HECU with a new one, re-inputting the variant code, replacing the EEPROM with a new one, and checking codes and inputting the correct one. By following these solutions, you can repair the Hyundai C1702 Code error easily and get your system up and running again.
