Short story..
I installed lowering springs, prior to I never got this code. C1424, C1427 and C1430.
I bought a used ADCM module.. and succefully configured it but it tells me “Unable to clear all codes”
Example
“Diagnostic trouble code 0x5424 has been read from the ADRC”
There are 3 of those messages pertaining to 3 of my shocks.
No one has been able to help me with this code.. I’m sort of ok with living with the code but in actually I want it gone.

Should I try buying another module? I’ve unplugged and plugged back in each damper. I’m told the solenoid is within the shock, my question is.. if I have the same shocks as before when I don’t have any codes.. why am I getting some now.
I aslo have the Temporarily disabled ABS fault. I may need a new ABS module as well. Are these 2 problems connected?

I’d like to also express that when configuring the used ADCM, it says it’s configured successfully if I followed to ignition “on” and “off” steps without turning the car on. I then tried to follow the steps by actually turning the car on when it says “switch ignition to on” and not just turning the key to position ‘2’. I then get a code saying I can’t connect to the ECM? How can I not connect to the ECM but I can read and erase other codes? It doesn’t make sense.

any and all advice is Helpful.

 

Possible cannot connect is clone vcm if using. I had that intermittent also for different programming. Finally found a genuine drewtech and never had it since. It almost seems you may need to access ccf files in engineering mode and revert to standard non cats shocks if possible. Just guessing

 

Can you give me more information on reverting? I wanted to switch to coilovers.. I’m sure the code won’t go away and I heard you’d need to bypass the dampers. I may have to try again with the OEM one

 

as far as i know all s type r vehicles came standard with cats suspension. You may be able to configure the car in the ccf files as being non cats is what i meant. Being that cats was a standatd feature and not an option it may not be possible. You might try the xjr forum and see how members there put on coilovers and deleted the air suspension. I would think eliminating cats would be similar

 

Ok, much appreciated. Thank you for the advice🤝
