What are the codes? Not plugging in the alternator will just set more codes as well as make the car shut down due to low voltage, and the low voltage will likely trip the immobilizer system.
Freeze frame data is stored when the first code (some store multiple frames but not yours) turns on the light. It will tell you what the engine was doing at the moment the code was triggered, Engine rpm, transmission status, vehicle speed, fuel trims, engine temperature, vacuum, throttle position and more. To use it you need to know what the first code was, then what the parameters for setting the code are.
So say you have a code telling you that you have multiple misfires (P0300), You look at the freeze frame data and see that the code was set on a day that was 40 degrees outside, that the engine temperature was the same and that the engine was at a high idle when the code was set. With that data I would start looking for a vacuum leak, probably on or around the intake manifold because the code was set on a cold engine and showed a multiple random misfire.
Fuel pump inertia switch only trips if the car is jolted real good, it is behind the right wheel arch. Fuse 16 is the pump fuse.
Pulling fuses will not give you regular brakes, it will however set a bunch of codes and cause changes in how the transmission shifts and the engine runs. Newer ABS systems are very integrated into the vehicle controls. The power-train module will get very upset if the ABS module goes offline.
That vehicle has both passive and active anti-theft. The system is spread through the various control modules to prevent any one part from overriding the system if it is removed. Would not be much good as a theft prevention item if you could pull a fuse or remove a wire to disable it.
