HELP CHEVY CAPRICE L99 TROUBLE CODES

[mastermind]

Greetings forum, I not long registered and poorly understand on-English. Today I decided to diagnose my car- chevy caprice 94 l99 through the eehack program and got 3 errors in the main body:

ECM TROUBLE CODES:
MALF43A (MALF 43A ACTIVE)
ERR43 (ESC FAILURE)
ERR95 (OIL LIFE LAMP CIRCUIT FAULT)
further I saw in diag that there is no information on 47 components and was in of shock !(see photo).I also want to say that there is no EGR, it is completely removed, 2 fans work and the check is lit. Guys write, I want to cut the EGR out of the brain machine, just don't know how, please help me!

The “No Data” in the Diag tab is because you have not enabled the tab. While connected, click either the “Stream” or “Snapshot” buttons on the right side of the screen to request the data for that screen. Since these are just error codes, “Snapshot” should work just fine.

ESC Failure is likely because the resistor in one or both of your knock sensors has failed. You can either create a BIN for your vehicle that disables this error code using TunerPro, or you can replace the knock sensors. 99% of the time this error does not actually mean the knock sensor has failed, but just that the detection circuit has failed. It is up to you how you want to solve it.

Oil Life Lamp Circuit Fault is easy, Check to make sure the bulb is not blown for the “CHANGE OIL” light.

Good luck.

Hiya
I've had the ERR43 & MALF43A codes on my '95 Z28 occur when the headers melted the knock sensor cables.
Very intermittant and hard to diagnose as cables all test OK.

Do you mean that you had normal knock sensors, wiring problems?

Who can write how to remove egr or these sensors, who has stable firmware for l99 94!

what language do you speak? maybe someone here can help translate for you

we call firmware 'bin'

you have stable firmware already. flash -> download bin from ECM

if you want to remove EGR or knock sensors use tunerpro. use eex definition from my site.

Sensors were new. cables tested ok. Knock circuit tested ok many times.
The cables were occasionally rubbing on the frame causing a short.

Guys, and anyone has a good and qualitative firmware on l99 caprice?

We keep trying to tell you that you already have it. Download the BIN from your L99 Caprice, then modify it yourself using the free program TunerPro.

Or upload the BIN file here and I can make the changes for you to disable the errors.

I understand, but I want to adjust my l99 to the correct values and am looking for a person who knows, for example, how many of me.t have his lt1 parameters for what would the car go better ! Well if I'll give you the bin file you will be able to configure the l99 and clean EGR?

If you have many any other changes to the L99 besides deleting the EGR, I can’t help you; I’m not qualified to be a remote tuner. But if you upload your BIN then changing things like knock sensors and EGR is very simple.

But I would do the exact same thing you would, I am not doing anything special only I can do. I really do suggest you install the free program TunerPro and use the XDF definition steveo provided above to open your BIN and edit it yourself. It will make you much more useful if you take a few hours to learn to do it yourself than to constantly post on forums asking other people to do it for you. Please do consider it.

[mastermind]

Well, I'll send you bin, I hope you show me what to do for cleaning the egr)

Everything turned out, the machine worked without errors !thank you all, guys, and one more question, there was an accident: the pillows worked, later the pillows and sensors were replaced, but the air BAG shows all the time on the appliances what is the reason ?

I downloaded the firmware, where do you throw ? And still the speedometer shows all contrary kilometers in miles, and miles in kilometers this itself the speed and mileage!

I assume by “pillows” you mean airbags went off. I don’t have any experience with the SRS computer and what it expects, but I would guess that your replacement airbag is not sending the right signals. Hopefully someone here has experience with repairing an airbag system.

To upload the BIN, you can attach it to a post. Click “Go Advanced” below the text box, then click “Manage Attachments.” In the new window, load your BIN file then click “Upload.” Once it is done you can close the Manage Attachments window. Then just submit your post!

As for your speedometer issue, the fact that your airbags deployed and you had someone “repair” them makes me think they have messed up some wiring in the dash.

CAN'T THE SPEEDOMETER BE CHANGED IN TUNER PRO?
