Questions On C5 EBCM Module Issue
I understand that a new Electronic Brake Control Module is difficult to find for C5s 1997-2000.
1. Is this because it was made in Germany by Bosch and is no longer made?
2. Is the ECBM more readily available for C5s from 2001-2004?
I am trying to learn from you guys so I can purchase a C5 more intelligently.

The 2001 and up EBCM can be rebuilt in some instances from several sources and at my last check was still available from GM.
The modules for the early cars 97-2000 are no longer manufactured and used ones go for a premium price. More than I would want to pay IMHO.
It is just a matter of time that the newer EBCM will no longer be available new. The other side of this is the newer ones can be rebuilt in some cases.

Jim,
Not to rain on your parade but Steering Position Sensors are no longer made or available for 99-00 C5's either. Just another sought after,high $$$$ used part like the EBCM.
I can understand your concerns on parts availability for 97-00 C5's.
If your on a budget then that's a huge factor in purchasing a C5.
On the other hand, if your not in a rush save your hard earned $$$$ and consider looking for a 2001 and newer C5. Parts are still available , to a degree and much better refinements were made to the later year C5's.

Thanks for confirming my conclusion.

There were a lot of platform updates made in the ‘01 model year and some after that.

Has anyone looked at other gm vehicles to use or modify for those parts that are no longer made? I know the Cadillac Eldorado uses awfully close headlights to a c5.

Jim where are you located? I have been thinking about selling my Z51 auto '04. Beautiful car being black on black. Pm me for pics and info if you are interested. Just don't drive it much since the divorce.

It looks like EBCM is no longer available for the 2001.

That is not 100% accurate..... 
The upgrade process to the later year EBCM ONLY applies to mid model year 98's through 2000 that also have the then optional Active Handling RPO (JL4). So far no one has reported retrofitting the later year (2001 - 2004) EBCM into a NON Active Handling early year C5. The later year EBCM had the functionality for Active Handling built into it as a standard feature so using it on a NON Active Handling C5 adds an additional challenge. AH was a standard feature on 2001 and later year C5's.

If a resident computer/electronic wizard could come up with a fix that would turn off the warnings, lights, bells and buzzers it would make a lot of people happy. I really don't need ABS, active handling or traction control.

A prevailing issue that attributed to the elimination of stock is that many C5s when still relatively new suffered from EBCM issues and had them replaced under warranty. As there was such a large differentiation in styles used pre-2001 - cars with or without AH, 97-mid 98 having different location than late 98-04 cars, etc, etc - it effectively dwindled stock. 01-04 are more streamlined as some things like AH became standard equipment by this time, which eliminated the need to say have two different types of EBCM based on if the car carried AH.
I will say though keep in mind that many - including myself - are still driving pre-01 C5s, have had or are having EBCM and similar issues, and still drive the cars just fine. They still start, move, turn, stop, just like normal. It's also just one of those things you deal with when you own an old car like a C5.

Until recently, a company was advertising rebuilt early EBCM's, but only for the ABS only, pre-AH cars, i.e. '97's and some '98's. Last time I looked I could not find any trace of anyone still offering those rebuilds.
Does anyone know whether having to clear the warning you get if ABS is not working would cause a fail on various state inspections? I know Maryland where I used to live is very picky, but where I live now is pretty much lights, wipers, horn and indicators/brake lights, plus a quick tire tread "look see". They don't even get in the car, just give the driver instructions as to what to turn on or off.
