FX3 Selective Ride Control

[Bob Seliga]

I just received the Fault code diagnostic grounding plugs and the manual from Gordon Killebrew yesterday. Everything checked out fine except the Ride Control System. Each and every code showed up as a fault. Is there a main controller that might cause this to happen? I can't believe that each individual part of the system went out at the same time.

The brain is mounted in the compartment with the ABS controller.

I would clear the codes and then start the car again and go from there.

The most common problem is the rod in the shock that turns to adjust the ride, it starts to bind and will cause the gear that turns it to break/strip. Some have had success making a new gear out of star washers after getting the shock fixed by Bilsteen.

Thanks for the help. I cleared the codes and got code 33 showing the LR out of position. Pulled the shock and the little gear on top has a broken tooth. Can this be replaced or does the shock need to go back to Bilstein?

I would send the shock to be redone. The gear usually breaks because the rod begins to bind up.

I have the same problem of Bob...i have done the Fx3 ALDL test and i have all the error code.
How i can delete/erase these error??
Thanks in advance

Ps: i read a lot of pages of this forum and i give you my compliments for that, it's very interesting...i learn a lot of things!!!!!
Bye

Bob take a look at the link for repairs to the actuator.

:cheers:

Tom, thanks for the link, but i need the method to delete the memory of Fx3 Chip...

Thanks again

Max, I have a 90 and I know that there was changes made in the system in the 92(?) thru 95's. I know Jeffvette made a thread and it's here somewhere.

In a 90 to clear all the codes you will find the "C" terminal pin on the ALDL connector. Ground Pin "C" three times, each "grounding" of the pin "C" will be for a duration of two (2) seconds.

:cheers:

OK tom, i must put a cable to pin "C" and the "-" pole of the battery (or the body vehicle) for 3 times and evry time have 2 seconds of duration. It's right?
Thank you
Max

One of the ALDL pinouts is the ground. I believe it is the "A" pinout, or the upper right one when looking straight at it. You can use a short length of wire or a paper clip to ground whatever pin (C in this case) to it.

[max76]

Yes Aurora,the A pin is the first on the right upper....I must do this operation with the key turn at first position?
Thanks again

Max, sorry for not being complete! My bad.

Yes as Aurora40 said you can use the "A" pin in the ALDL as it is the system ground. Or if you wish you could use the seat track as a place to ground on to.

Tom, no problem...i have done the test and now the chip is clear...i also control the actuator and when you turn the key in first position the actuator gear move it.
In next days i'll try the car and i can say if there is some other error.
Thanks for the moment!!!!

Max, an error will show up immediately, as the system self checks at the key on position. So if the light is currently out, you have no codes.

Thanks Jeff,
But the shocks (for me) are so much soft. If the controller is in tour the shocks are soft (with the car stop)OK??
If i turn the controller on perf and i push on the hood the shocks are always soft too, at the same way...:dontknow:
I think that my shocks are toast...what do you think??

The shocks are a progressive system. When parked, the settings are on the softest setting. The big thing is when driving at around 160 Kmh, does the front end seem to float around? But as the shocks age they do deteriorate even when not in use.

The controller makes the shock settings stiffer every 20 mph speed increase.
Checking the shocks with the vehicle stationary is not a good test as you have found.

Ok guys...Today is a sunny day here, after a week of big rain...i'll try the car in next days, i think that my shocks are toast also if the Z have low mileage, but always 20years!!!
Thanks at all for the HELP!!!!!!
