HELP CHEVY CAPRICE L99 TROUBLE CODES

[mastermind]

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.

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?

[NomakeWan]

It can be changed--but what is changed is the ratio to calibrate the speedometer for different rear axle gearing or tire sizes. It is not for switching between metric and imperial measurements. That's controlled by your CCM and the dash switches.

I have attached an updated version of your BIN to this post. In this version, I have disabled the ERR43 code but left your knock feedback intact; this assumes your error is coming from the resistor in the knock sensor and is not actually a knock sensor failure. I have disabled the EGR codes and have set the minimum speed for the EGR diagnostic to 255, which it will never hit so the EGR will never try to actuate. I have also disabled the diagnostic code for the oil life lamp.

You can do all of these things yourself, very very easily. Get the free program "TunerPro" and install it. Get the XDF definition file steveo linked you earlier in this thread, also free. Run TunerPro. Click XDF->Select XDF and open the XDF file steveo linked you. Now open your BIN file in TunerPro with File->Open Bin... and voila, you can edit your own cars all on your own. It will also help to change the "View By:" on the left to "Parameter Category" to make things easier to edit.

Best of luck.

Error err43 I fixed it. There was a broken wire on the sensor! You fixed all the constants on the name of the Egr? Simply I need only to you removed EGR) thank You you!

[NomakeWan]

Glad to hear you fixed it! Congrats!

On the EGR, I disabled the error codes, plus disabled the EGR diagnostic procedure by telling the computer to only run the diagnostic if vehicle speed exceeds 255--which it can't, effectively disabling it. Go ahead and give it a try, it should work. :)

did the knock sensor , but didn't go anywhere! today went I include D and LIGHTS up CHECK, I carry out diagnostics and I see an error: ERR34 (MAP SENSOR LOW) pressure small! see the photo below, the sensor died ?
