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. 2005 4.4 N62 LHD Sent from my BBF100-6 using Xoutpost.com mobile app |

I do indeed have inpa. How do I check the level of the sensors in INPA? |

2 axle air suspension EHC Read Status Analog F1 this showed me that my height front right wasnt getting any reading. Sent from my BBF100-6 using Xoutpost.com mobile app |
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 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. |

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. Quote:

I’ve been reading and studying like crazy. That line in Clavurion’s post is the line that deletes the EHC? This is done in text editor? You had mentioned you had to recode the truck from 4.8 to 4.4. Was this necessary to get the ehc module delete to stick? After I get this done I will compile a diy write up for all of the future peeps that will need to do this mod. |
Hi guys -
without rushing this, I switched to coilvers some months ago and am gradually putting together the mental picture of how to go about sidestepping the EHC to avoid the dash warning.... Might you perhaps have time to give us a step-through for myself and a friend to succeed at this too?? |
I started to put together a diy and had to stop unexpectedly. I’m happy to post the screen shots and directions as far as I got when I get back from out of town next week. It’s complicated and scary but if you follow along with this thread and the info Clavurion and Crystalworks give throughout it, you can be just about ready to tackle the errors. You have to know what you’re doing. Read through as much as you can. Crystalworks and Clavurion are super helpful but know in advance what you need to ask. That was the challenging part for me. You’ll get it and you’ll be fine just put in the work.

That would be amazing - I am full of trepidation about it since I have only used INPA and not even NCS Expert/Dummy before, and my friend is gonna do as much homework as possible on the checksums and everything cos he is that kind of perfectionist!! :stickpoke:rofl::rofl::rofl:

Okay - I'm feeling fairly confident to do this - I just did a dry run on opening some module output in NCS Dummy, but one weird thing is that when I went to edit the FA in NCS Expert, there was nothing in the list!!
Also it gets the correct last 7 digits of my VIN from the KMB, then adds a number 9 to the end... :shrugs: |
