Fault reading
![Fault display](http://checkelec.com/wp-content/uploads/2018/03/faults_1.png)
This screen displays faults logged by the ECU if any.
Fault clearing
![Fault swipe](http://checkelec.com/wp-content/uploads/2018/03/faults_2.png)
To clear the faults, swipe them to the side of the screen.
It is not possible to perform this operation if the car ignition is turned-on.

A command is sent to the ECU to request a fault clearing.

If the command succeeded, the faults are cleared and a green message displays “No Fault”.
If it is not the case, there could be two reasons :
- The command was not properly received by the ECU and thus not taken into account. Try to repeat the operation.
- The displayed faults are not clearable. Some faults like the “Wrong ECU parameters” fault will be cleared only if the problem is fixed.
