How do you deactivate the alarm system of the Smart 450?

Model: Smart Smart 450 - Years 1998-2007
Part: Checks and maintenance

Let's talk about the Smart 450, a car for which a presentation video has been inserted, delving into the topic of anti-theft. Is it possible to bypass the anti-theft system? Since we are dealing with electronic and electrical components, yes, it is possible to do so, with some experience in the field and knowing where to make modifications. In practice, one must act on the cables that communicate to the car's ECU the activation of the alarm, which should appear as activated even if it is not in reality. These are usually temporary operations, done while waiting to complete maintenance operations, after which everything returns to normal.
