Q45a active question -- loud pop and then active no more...

[jerrodl]

I was driving my '94 Q45a and heard a loud pop and the active suspension ceased to work (light came on, too). There isn't any leaking and I can't seem to see anything electrical wrong but the sound seemed like it came from under the car (really hard to tell, the stereo was on pretty loud). I've heard some relays make loud noises when they go but thought it might be hydraulic, too (but no leaks!......hmmmmm).

If anyone has an idea what it might be or the likely suspects, let me know. I would take it to a Q45a expert in the Minneapolis area if there's one that anyone here knows about. Let me know on that, too.

Thanks in advance,

J

typical sound of the fail-safe valve.it should reset and start working again.can try the stored code key ON, no start, rock N-H switch more than 10 time in 10 sec. go from N-H-N, leaving on N. wait ~10 sec and look for bliping actsus lite. post up code other than 55 (55 = no fault), and we'll see.

check actsus fruid [sic] level. make sure your battery (a good one interstate megatron plus or optima red-top) is fully charged and connections clean and tite.check alternator, i hope you have an OEM remanned --no aftermarket junk here.

actsus on the 94-95 is VERY sensitive to voltage fluctuations.did i say VERY sensitive?i mean VERY sensitive.
