So my 05 RX8 has an unusual problem. The traction control light, the Orange one in the middle of the tach, stays on. Doesn't matter if I reset the ecu, remove the battery etc it just isn't playing the game. Abs still works, and I still have to turn the wheel full left then full right to clear the TCS OFF light when I remove the battery, but tcs still isn't working. The fuse under the bonnet is fine too. Any ideas?
