SO you changed the BCM? How did you program the options the car has into it?

ZeroGravity

. Yesterday I planed to check will 2001 EBCM work with 99 BCM. I confused the 2001 BCM with a 99. And right now installed 99 BCM and it WORKS. Then I tried to replace 99 BCM with 01. Security light is flashing and nothing happens. Starter doesn't throttling.

My main car is 99 hardtop poor packaging. Two years ago I bought another one whole 2001 Vette. It was a convertible with all options. . Car was partly incomplete. Custom cleared as parts not a whole car. Not a criminal but not available to drive for law reasons. It wasn't cheap. But it was a great warranty to complete a EBCM swap anyway.
Also I swaped telescopic column but not adjust it yet. I need a Tech 2 and gonna buy a Chinese clone. Sport seats and HUD was swapped to.

I know that 97-2000 Vette's brake issue is a butt hurt for lots of people. I'm working a lot so cannot spend many time with my Vette. But I promise that someday it will write a full topic about solvation of the problem

ZeroGravity

No, I didn't. Thank you for info. Telescopic column is a 01+ option so I need later model BCM anyway.

Something tells me he's got a lot of issues now and some he doesn't know about yet with this "conversion" . I wouldn't get too excited till he got it on the road for a while to see what the system actually does. I'm betting the "butt hurt" is far from over.

please please please keep us updated on what you have done and are doing!!!

I am desperate for this to work!!!

I remember your thread but it just died.

Did you drive the car yet?

If no, did it start and not give any errors or light the ABS or traction lights?

If no errors or lights, could you turn the traction control off and back on with the button?

Did you try holding the button for 5 seconds to see if the car would go into competition mode?

ZeroGravity

Thread died. But idea never.

Yes I drive it. Now I DIY some body works (flared fenders, hood with blister for Magnacharger), and I have no insurance until the car is fully completed. So now the car is without fenders and hood. But twice or bit more a weak I doing a test-drive at a sduburb road without police.

Yes.It has only traction light. Eror is C1288. I am 99% sure that the reason is wrong installation of a used SWPS from salvaged car. And when the re-calibration will be done everything will be OK.


I didn't all of this. Now cabin is disassembled. I'll try to do it after SWPS issues will be solved.
Traction is enable. ABS is enable too.

Please wait a bit. A weak ago I had a new fault. C1255 H C. That is a WSS. So when I'm driving faster than 20mph lights are on. ABS does not have time to work. But traction have it. So I cannot show you full functionality.

Please give me a time. Solvation of WSS and SWPS errors is needed. After that I could show you a video.

Also I need a remind of all wire connection. Which wire from old EBCM going to new EBCM.

grasshopper645

Sounds promising! ! Post a video when you can, you have no idea how much help you will have been if this works!

lionelhutz

It sounds like you are close.

The SWPS and wheel sensors are direct wired to the EBCM so there should be no reason the car model year affects them working.

I'm not sure what recalibration you are expecting to do for the SWPS though?

ZeroGravity

Briefly, absolutely new sensor "from box" is already calibrated. It has a special pin for this.

But used one requires proper installation (calibration). A Tech2 is needed, but people figured out how to do it using just a voltmeter.

I didn't know that when instaled SWPS from salvaged car.

grasshopper645

OK so what year is the swps from? its a '01+ right? the pre '01 swps is discontinued. And yeah if the locking pin isn't installed you will need to calibrate it to centre position.

ZeroGravity

It is 2001 year SWPS of course. For 2001 EBCM. Removed from 2001 convertible.

grasshopper645

OK cool so what is next step?

Callibrate swps

Then what?

ZeroGravity

Next step is check WSS wiring. Calibrate SWPS is last step. ABS and TRC already works fine. But I cannot show it until WSS issue is gone.

lionelhutz

I doubt the voltmeter calibration, which is really centering the sensor and not a calibration at all, will work on that sensor. The older sensors had an analog voltage you set to 2.5V or so to center them. The newer style doesn't have that output.

lionelhutz

Check in the WSS connectors for damaged pins.

ZeroGravity

lionelhutz
Of course. First step is check connectors and wiring of left front sensor.

So it is impossible to adjust used 2001+ sensor without a Tech 2?

lionelhutz

You found information that said to measure the DC voltage, right? Well, the analog DC voltage output doesn't exist on a 2001-2004 sensor so that method won't work on those sensors. All that exists are the phase A and B signals, which are basically digital on-off signals.

grasshopper645

What are the chances of the 01+ sensors being discontinued?

Almost zero in the next few years....
