First of all, let’s learn something about injector coding.
- 1.Write injector actual code or rewrite code in the ECU to the injector code of the corresponding cylinder so as to more accurately control or correct cylinder injection quantity.
- 2.After the ECU or injector is replaced, injector code of each cylinder must be confirmed or re-coded so that the cylinder can better identify injectors to accurately control fuel injection.
Case: When turn on the ignition switch, the engine warning light flashes on the dashboard.
Device used:
XTOOL H6 Pro with VCI box (A80 Pro with VCI box is also OK)
Main steps:
- Step 1: Read/write injector code
- Step 2: Clear engine trouble code
…
Step 1: Read/write injector code
After connecting XTOOL VCI to the vehicle via main cable, and connecting to XTOOL tablet via Bluetooth
Select Diagnosis-> Service -> Injector Coding-> Asian cars-> HYUNDAI-> i20 (PB)-> 2013-2016
Turn the ignition switch on
Read injector code firstly, and then write injector code (ONE)
There are three injector codes are read out
Depend on it and write three injector codes in sequence
All injector codes are written successfully, but the engine warning light still appears on the dashboard when start the car. So also need to clear the related engine trouble code.
Step 2: Clear engine trouble code
Back to H6 Pro (A80 Pro) main menu
Select Diagnosis-> Asia-> HYUNDAI-> Manual Selection-> General-> i20 (PB)-> 2016-> D1.1 TCI- U2-> System selection-> Engine control
1.Read ECU information
Read the ECU info successfully
2.Read trouble code
The fault code read out is P1670- invalid injector IQA/C21
3.Clear trouble code
Go to clear the fault code (make sure the ignition is turned on and the engine does not start)
When the fault code is cleared, go to read trouble code again. If it shows “No fault code present”, it means the code has been cleared successfully.
Finally, turn on the ignition to check the dashboard again, the engine warning light disappears.
Done!
