If there is a problem uploading to the ECU, such as interrupt of vehicle power, then the ECU will be left in 'recovery mode'. In this mode the ECU will not run the engine, but can still be re-programmed or reflashed.
Identifying when the ECU is in recovery mode
When the ECU is in recovery mode the status bar will display an exclamation icon:
Recovering the ECU
| 1. | Upload a calibration to the ECU. It can be the same calibration as previously uploaded. |
| 2. | Important: Switch the ignition off and then back on. |
| 3. | Check that the ECU icon changes to indicate the ECU is not in recovery mode. |
