Service Ride Control Code 14

[Jason 91]

I’m a little confused on how to proceed with the diagnosis on this code now. I originally retrieved only code 14, but I now have codes 23, 32 and 33. I think I got these additional codes because I turned the key while having the actuators disconnected and I did this more than a couple of times which is why I think I also got code 23.

To give you some information on my car, it is a bone stock 1991 with 49,9XX miles and, as far as I know, original shocks and actuators. Also, I do have the factory service manuals including the electrical diagnosis supplement so I was able to follow the chart for code 14.

Here’s what I was able to confirm;

Observed dampening adjustment gear turn temporarily
Measured voltage of terminals and they were all around 5v
Turned dampening adjustment motor control shaft on shock and moved it with what seamed to be very slight friction from side to side
Observed that the connection to the harness was clean and tight

On the dampening adjustment motor control shaft on the shock, I wasn’t real sure how exactly it should feel (it didn’t seem like friction to me) so I felt the left side and it turned and stopped exactly the same and there was no code associated with that side so I’m assuming my shock is good.

So here is where I’m confused. Based on what I’ve done, the chart says to replace the suspect actuator. Given the fact that the dampening adjustment gear does turn temporarily, I don’t want to just “replace the suspect actuator” because these things aren’t exactly cheap. I’m looking for something a more concrete here in order to properly diagnose this.



I’m not sure if this matters or not, but let me also add that the left side is far more oily than the right side. There are no drips – just more oil. Visually inspecting these the old fashioned way would tell me to replace something there on the left side yet I got no code for the left side.

I’m appreciative of any thoughts or suggestions on how to proceed.

Thanks,

Jason
