From SlickGT1 (Denis's) sig:

To view the OBC test:
) Key to ignition pos 2 (no need to start engine).
2) Fasten the seat belt to get rid of the “Fasten Seat Belt” message.
3) Press the right button on the instrument panel, and hold it until “TEST-NR. 01″ comes up (5 to 10 seconds).
4) Press the left button on the instrument panel, and the vehicle id comes up (last 7 digits of VIN).
5) Add up the last 5 digits to get the “unlock code”, e.g. the unlock code for “AB12345″ would be 15 (1+2+3+4+5).
6) Repeatedly press the right button until “TEST-NR. 19″ appears.
7) Press left button -> “LOCK : ON”
8. Repeatedly press left button until “LOCK : xx” appears, where “xx” is your unlock code.
9. Press the right button. All modes are unlocked now.

You have low cluster and not high cluster S? Have you had the car coded at all? I had the "key in ignition" gong turned off via coding so that it would stop dinging when I was cleaning out my car interior or drying off the car and had my doors open after washing, so now when my door is open it does not display "key in ignition lock" nor does it chime anymore. If you have the display still then maybe you need to "Test the gong" lol
