So the suspension is playing up but there is no manual available for its use as the 1994 suspension is HICAS and it seems like the 1990 is different the HICAS doesn't seem to have any actuators for nitrous afaik from looking through the manual. So if anyone has the 1990 Q45a manual, elwesso thinks there is bugger all difference between the 1990 Q45a and the 1994, speaking to someone who fiddles with many different machines says there are so many small things that can be different variations in measurement etc how come these manuals aren't available when I know someone who does have them but isn't willing to share.

Did you import your Q45?

If not then you don't have a 1990Q45A.

But the 1994 Q45 manual is that same for the "1990 Q45A" just look in the FA section.

GOD I think I have memorized the entire FSM sections.

HICAS is 4 wheel steering which are two different thing compared to active suspension. Active suspension and HICAS were never offered togther because of the lack of space and extreme maintenance costs.

In US the 1991 year FSM was first active, so 91-93 FSM are spot on for your use. 1994 had only software changes to active system.

Hey Paul

Thanks for your reply after reading my post I realised the HICAS had nothing to do with the suspension and was more to do with the steering. I haven't been able to find anything on th suspension in the manuals.

Ok well I found the active suspension stuff in the manual, I must have missed it on the day due to being exhausted all day. Anyways thanks everyone.
