Iveco Daily Fault Codes List

To access and clear error codes stored in the control unit memory, follow these steps:

1. Turn off the key and press the diagnosis button.
2. Two sets of flashes from the EDC warning light with a short pause in between indicate the code number of the first stored error.
3. Press the button again to proceed to the next error.
4. Once the last error is reached, the cycle starts again from the first error.
5. The error list includes all errors stored in memory, not just the active ones.
6. The presentation order of the errors follows the chronological order in which they occurred.

To delete the error code list from the control unit memory, perform the following procedure:

1. Turn off the key and press the diagnosis button.
2. While holding the button, turn the key on.
3. Keep the button pressed for 5 seconds.
4. Release the button.
5. Turn off the key.
