Pulsating brake pedal indicates that the ABS is active under brakes whether it is required or not
from the rest I would first have a fault scan done to find any faulty sensors
Try replacing the ECM with a known good unit as the scan fault readings may reveal a problem ECM
That sounds like a bad charging system. Auto zone can check your alternator and battery in your vehicle. EVERYTHING in that need electricity. when it starts getting low weird things start happening.
Testimonial: "I did feel something today, tried it out again today for a drive to see if it still does it and now I feel the altantor is losing power when I push the breaks to stop ?"
Did you get your problem fixed ? My car did the same thing and every mechanic said it was an engine problem. Sure feels like it but it's not! It's a simple fix and I'm a girl and I did it myself. It's more than likely a sensor wire harness needs to be replace. Just so you know it's not your master cylinder or your alternator is not your abs it's a broken harness wire from the engine down to the connection behind tire to the abs.

if you have an awd light coming on then you have an awd transmission(car).if the brake pedal is pulsing while pushing on it to come to a stop then it sounds like the rotors are warped and need replacing.this can be caused by alot of heat build up on the rotors,a lot of miles on them,the wheel nuts were not torqued when tightened,rotors are rusting and coming apart,a loose brake pad moving around.get the brakes checked.
