The bearings on the wheels has to be installed one way only, the rotor ring is built into the bearing and if installed the wrong way round the sensor cant pick up the wheel speed causing the ligt to be switched on in the cluster. The diagnostic equipment should pick this up as a fault once the car has been driven, it will see the sensor when you do the diagnostic if the car is standing still but once the car is moving and no signal is send from that wheel it would register a fault into the memory of the PCM that you would be able to retrieve later.
There is a way for you to test the sensor yourself by using a multimeter set on volts, you jack the vehicle up at that wheel, install a vehicle stand to support the vehicle to be safe, disconect the wheel speed sensor and probe the two wires into the sensor, spin the wheel by hand and a small amount of current will be produced meaning the the sensor is working and the wheel bearing is installed the correct way, you can also do a continuaty test on the sensor by switching the multimeter onto ohms, but be very carefull, if this sensor has three wires you cant do the continuaty test because of the integrated circuit in the sensor, the three wire sensors opperate on a voltage from 5Volt and it would be destroyed by the multimeter opperating on 9Volt.
If the continuaty test passes and the bearing is installed the correct way, the most comon fault would be a break in the wiring leading to the PCM
Hope this will be helpfull.

ABS and traction control really are only for panic stops and if your tires slip on wet surface's and yes each tire has a sensor on it. However if the brake light comes on this has nothing to do with the ABS or traction control lights. It's not a parking brake light. This light tells you, you have a serious brake problem.

The tire pressure monitor detects any changes in the tire inflation
pressure. Therefore, it must initialize and store it in its memory if
the tires or wheels have been replaced, re-inflated or the tires have
been rotated. You should be able to re-initialize the system by following these
1. check and make sure that your tires are inflated to the correct pressure
2. turn the ignition switch to the ON position. If the low tire pressure warning light comes on, push and hold the tire pressure warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns off and then release the switch.
3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.
4. initialization is *not* completed until driving at the vehicle speed of 19 mph or over for more than one hour. the tire pressure monitoring starts when initialization is completed.
