All wheel drive systems typically use the abs sensors to measure tire rotation speed.

If a tire is low, it throws the reading off causing unneeded power transfers.

Traction control does the same.

some tpms use the ABS sensors to judge if a tire is low on air. This is actually a more dependable system than the independent pressure sensors.

So, in closing, check your tire pressure.

Probably because the system lost respons from one of your tmps sensors ... the tractioncontrolsystem requires the sensors to respond. Shutting down the tractioncontrolsystem is actually a safetyfeature because if it where to respond i could behave eratically because of the misding data
