Self leveling error coding help
 

I have a 2004 4.8 that I bought with coilovers already installed and the air suspension removed. I tried coding out the warning light with PA Soft by unchecking the box that displays “Self leveling suspension” errors but the warning message keeps coming back. Does anyone have any other insight on why this might be happening? What other steps can I take to get this warning light off of my dash? I have searched for a week online and have gotten nowhere. Please help!!!

Hi.

I did the same in PA Soft; however. warning also returned for me until I replaced a bad height level sensor.

The level sensors can be good, but positioned incorrectly and I would get the warning, or even when jacking up car high.

The levels of each sensor can easily be checked in INPA if you have.

Thank you!!
I do indeed have inpa. How do I check the level of the sensors in INPA?

Chassis
2 axle air suspension EHC
Read Status
Analog F1

this showed me that my height front right wasnt getting any reading.

The only codes that are popping up all involve height supply pressure exhaust valve. 3 of them. Supply height. Height pressure. Exhaust-valve. I have no idea where to start with those.. any suggestions?

You have to code the error out of the lkm. Or even better, use ncsexpert to delete the air suspension (by editing the zcs). Details are found in my bc racing coilovers thread.

I have everything I need to start coding but I have never done any coding in this car or ever. Do you happen to have a diy for us peeps who have no idea where to start to code out the ehc? I read the entire thread at least 4 times but I don’t even know enough to know what I don’t know... 🤷🏻*♂️

I was in the same boat. I've been wanting to get to a DIY but haven't had the time, sorry. I'll do it eventually but homeschooling our daughter, caring for our son, remodeling my in-laws restroom, and a host of other things have kept me from having anything even closely relating to "free time."

Editing the ZCS is a pain. Clavurion gave me clues and aid, but piecing the actual adding and subtracting was a learning curve experience that had me reading multiple coding sites and forum posts. I plan on doing a step by step eventually. I know that doesn't help you now though.

Were you changing the VO to remove the EHC module completely or did you go in and manually remove the ehc module. If it’s the latter, what command/code removes the module or is it just a matter of removing a line of code?

E46, e53, and I believe e39 all use ZCS codes rather than VO coding for options/build specs for the modules. You would have to edit the zcs for your truck to reflect removing the ehc system. In ncsexpert when you edit the zcs it will code pertinent modules to reflect the deletion of ehc.

It's confusing. And complicated. I feel your pain. I did at least a month of reading before attempting to clear the errors via editing the zcs. Even after all that reading clavurion was a big help in dealing with the special circumstance of having a 4.8is and coding out ehc2.

Edit: From my thread I linked.

This thread was helpful.

And this website was SUPER helpful in illustrating what Clavurion is talking about.
