Symptom: ECU upgrade in progress, error code [5021-31-7000]
Cause: For ECU upgrade erase memory or check dependency command, no response from controller or specified timeout
Resolution:
1. It is necessary to check whether the car is equipped with aftermarket equipment.
2. It is necessary to connect the diagnostic device and check the normal display of the sensor output of the target controller.
3. If the connection status and sensor output are normal, retry the ECU upgrade.
4. If the same failure occurs even after retrying, it is necessary to test with the file with the timing changed by requesting GIT.
In case the above workaround doesn't resolve the issue, please contact your distributor or GIT assistance at following email for further support.
