As you can see from my page references, there are 23 pages in the workshop manual on this - hardly room in a posting to the forum! To set the ball rolling and the light flashing:
1.Ign OFF
2.Gear shift to P or N (auto) or neutral (manual)
3. Ign ON
4.Immediately start engine
5. Turn steering wheel L to R 5 times or more and depress brake pedal at least 5 times within 10 seconds of Ign ON (!<img src="http://www.zclub.net/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt='

6. Depress and release foot brake
7. Turn steering wheel L to R (at least 20 degrees of movement)
8. Auto: move gear shift to any gear position then return to neutral. Manual: depress clutch move into any gear position then return to neutral.
9.Move car at least 10 feet forward at (at least) 1 mph
10. HICAS warning lamp will start to flash.
0.25 second intervals: all systems normal
10 flashes followed by 5 second delay, then 9 code flashes (repeating) indicates a fault. Code flashes are 0.1 second for OK and 1 second for fault. Count which number flash is longer.
1=RH solenoid valve
2=LH solenoid valve
3=fail-safe valve
4=power st. solenoid valve
5=speed sensor input
6=steering angle sensor
7=steering neutral position indicator
8=auto parking brake sensor or, manual clutch sensor
9=auto inhibitor sensor or, manual neutral sensor
Cancel by turning off ignition. Auto cancel after 5 minutes or driving at 20mph or more.
Have fun......
