These are all unrelated...The traction system warning is likely a failed wheel speed sensor, you can lift each wheel one at a time and see if the sensor puts out voltage while spinning wheel whatever sensor doesnt needs to be replaced otherwise it can be hooked up to a high end scantoo lat shop to check abs codes. The service engine light can be many things if you know the codes let me know otherwise you can get them checked for free at parts store. Here are calibration instructions for compass.

The code is P0327

This code is related to the knock sensor, so replace knock sensor and it should take care of check engine light.

the knock sensor was replace and light still on

Then the next step is testing the wiring going to the sensor and if light is still on crank and cam sensor signals need to be monitored on scantool.
