How can you deactivate the ABS system in a vehicle?

The option indicating that the ABS (Anti-lock Braking System) can be deactivated by pulling the fuse is correct because removing the fuse disrupts the electrical supply to the ABS components, effectively preventing the system from functioning. This method is typically used for troubleshooting or if the system is malfunctioning and needs to be temporarily disabled.

Turning off the ignition contributes to deactivating the ABS as well, because when the power to the vehicle is cut, all the electrical systems, including ABS, cease operation. However, simply turning off the ignition is not a reliable or permanent method to ensure the ABS remains inactive; it would re-engage once the ignition is turned back on, unless the fuse is pulled.

Therefore, the combination of both actions in this context informs the correct choice, as each method confirms the potential to deactivate the ABS system under specific circumstances. It’s crucial to handle such systems with care since proper functionality is essential for vehicle safety.
