On electric vehicles, range depends largely on the type of driving you do. If you drive thriftily, the change will not cause you to lose range, it will probably even give you more. If you drive more sporty, you will naturally experience a drop in range. We estimate this to be about 5km in normal use.

**A few things need to be checked:** 1. Did you connect the small black box in the left-hand glove compartment correctly? 2. If you are using the OBD Y-extension, try without 3. If you are not using the OBD Y-extension, try plugging into the part without the switch 4. Check that the [fuse in the diagnostic socket](https://fr.e-guide.renault.com/fra/Twizy/FUSIBLES#:~:text=Prise%20diagnostic/Radio) is still working 5. Check if by connecting the box to a computer and to the OBD plug at the same time, the box works. If it does, your OBD plug is probably defective and does not deliver 12v. 6. If the case model you received has a translucent black shell, go directly to point 6. 7. If the case model you received has an opaque black shell, remove the shell using the screws on the back. 8. Check if the indicator light comes on when plugged into your Twizy. If not, try plugging into a conventional vehicle (other than Twizy)

**Procedure:** 1. Try putting a notch on the handbrake and see if the throttle works again. If so, it is a polarity problem on the handbrake. We can solve this with a software update, we invite you to [follow this procedure](https://www.notion.so/vdkworkspace/Polarity-fix-correction-polarit-f75582eadac749a5940a96c2ca1ee471). 2. Check the mounting of the controller. This type of problem can occur if you have reversed one of the terminals. 1.
