If you have TCL you have ASC... Unless someone's disabled it in the past/
From the code list thread here: http://ozvr4.com/forums/showthread.php?t=2415
TCL 35 - Steering Sensor (ST-1, 2, N) line
AYC 31 - Steer Sensor (ST-1, ST-2, ST-N) System (break)
So you have a Steering Sensor problem. As for where exactly, that I can't get out the Japanese manual to well... so start looking for broken conductors around the steering column etc.
