Sab, I tried it in my car (1992). Thats what I did:
1) Turn ignition ON and shut down AAC by pressing 0 button;
2) Turn OFF ignition;
3) Set left wheel to red detent and right wheel to blue detent;
4) Turn ON ignition;
5) Press AUTO (displays show HI/LO);
6) Within 20 s simultaneously press REST and 0 for >2 sec.
It worked for me.
What did your read from sensors?
