Your car battery is not enough to use with SDD.
You will also need an external power supply capable of 30A connected to the car

So:
Laptop with power supply

Car with good battery

External 12v DC 30A power supply connected across the + and - terminals under the bonnet. - you must set the power supply to give at least 12.8v when connected to the car with the ignition at position 2. Which means psu set to around 13.8v on no load.

You must keep the power supply connected while you use SDD or you risk the car bricking the module you are programming.
