JRZ & EDC Delete - Warning Lights Galore

So, installed the JRZ RS Two Coilover Setups a few weeks back along with the JRZ EDC Delete Modules. Since install, I get a chassis restriction message everytime I crank the car. I acknowledge it and it goes away besides leaving a yellow hazard triangle illuminated in the gauge cluster. Apex asked me to check the resistance in the delete modules and they seemed fine. Just the other evening I got all sorts of warning lights - see pic. I parked it and two days later after cranking the car, these warning had gone away. This evening while driving, they all came back on again and while stopped at a red light, my car died and had to be restarted. Any ideas? Could the edc cancellation modules be causing these issues? Maybe low battery voltage as my car sits a good bit?

I did remove the plugged in sensors that are mounted on the stock dampers as the jrz rears did not have a means of relocating these sensors to the new dampers. Could that be a problem?

do you anyone that can code out edc for you? I also installed jrz with deletion modules and wasn't able to use them bc the connector was different and wouldn't plug in. so I had a shop code it out, make sure you unplug the edc in trunk by battery also.
I also had a whole list of codes, I cleared with bm3 and they never came back

You have to code out EDC or plug one in of the relays to trick the system at each damper (ie 4 EDC delete relays needed).

Edc connection in the trunk?? Did not know about that one. I'll do so today and see if that helps. Thanks

I know of one shop here locally that may be able to code it out for me. Would prefer to use the cancellation relays from jrz as I paid for them though

The JRZ cancellation boxes will have more issues than coding them out. Coding them out will take 5 minutes and can be undone in the same amount of time btw.

Return it for that itself could pay for most of your labor.

Chuck the modules and get the car coded correctly. They're literally giant resistors.

Thanks for the replies. I'm going to disconnect thr wiring in the trunk and see if that does the trick. If not, see about simply returning them.

Think that may be causing all of the other issues??

Sorry about your car issues. How old are the dampers? There should be a manufacture date on the bottom of the shock.

The dampers are brand new jrz rs twos.
Taking it to a shop next week, going to trouble shoot the Chassis restriction error message. Since I unplugged the Edc module in the trunk, I have not gotten all of the other error messages.

All of these warnings just illuminated again. Taking it to a shop this week to clear it all and then see what pops back up and diagnose from there. Apex has been nice enough to offer a refund on the JRZ's Edc delete modules if they are not doing the job

The JRZ emulators are emulating each of the OEM struts (4), the EDC module needs to remain plugged in if continuing running this type of system.

Coding changes the VO to a non-EDC type enviroment (obviously, EDC system isn't used).

Shop checked it out, looks like the culprit may be a faulty wheel speed sensor. Going to drop off with them to tear into it tomorrow. Will report back

All good! The multitude of codes that came and went a few times were caused by a faulty wheel speed sensor. Replaced that and cleared the codes. The Chassis restriction code I originally had trouble with was due to the vertical motion/load sensors that attach to the stock dampers with edc. I had removed them as the Jrz units only have mounting points for them on the front dampers. Turns out the ecu is still looking for the signal from those sensors. Plugged them back in and tucked them away and everything is good!
