Symptom: ECU upgrade in progress, error code [5021-31-7F22]
Cause
1. Negative response from controller to ECU upgrade erase memory or check dependency command
2. The vehicle is not a target for the event that you are about to perform
3. If the ECU software being updated does not match the controller specifications, a popup will usually appear.
Resolution:
- Check if pre-conditions are met such as IG-ON(Engine off), 12V Battery condition.
- It is necessary to check which function of the AUTO mode or Manual mode was used to upgrade the ECU.
- If it was performed in manual mode, it is necessary to check whether the ECU upgrade was attempted in a small category suitable for the controller(ROM ID not corresponding).
- It is necessary to check whether the car is equipped with after-market equipment.
