I respect you C5 knowledge also! You have posted lots of good stuff.

You know, sometimes,, its NOT what you know but just how you go about saying it. There are forum members that know a LOT more than I do. I try to be fair with everyone and seldom slam or attack people.

I frequently give people my phone numbers and have even invited them over or even go to their house to help them fix their Corvettes. I'm not limited to C5's.

I take lots of pictures of my car and lots of pictures of cars that I have worked on and I have used some other members pictures (with permission) and I take lots of pictures of parts at Carslile. When you provide someone with a picture of the problem or a component, it really helps. Sometimes people just cant find those damn pesky ground points!

Thanks for the back up!

Internal power relay, huh. That doesn't sound too bad. Is the relay available somewhere? Is it easy to replace? Many guys on this forum have basic electronic skills and can solder a new relay on a printed circuit board. Is there a how-to?

 

Just about Everything is repairable. It all depends on how much experience you have and, time and money you want to spend or don't want to spend if your willing to break it down and repair it your self. There have been a dozen or so people on the forum that have ripped modules and components apart and figured out work around and repairs. There are post on repairs to the Door Control Modules, Instrument Panel Cluster, HVAC Control Panel, Wheel Speed Sensors, Tire Pressure Sensors and there are probably a few more.

I have personally ripped the EBTCM apart.







2001-2002 EBTCM

















As you can see, the module is potted in RTV and yep,,,it was a royal BITCH to separate the case from the module.

ABS fixer has researched this module and has perfected it's repair. He installs better relays and gives it a WARRANTY! There are certain EBTCM's that have issues that not even he can fix! The module contains a micro processor and I believe that if that it has an issue, "stick a fork in it,,it DONE!"

My module; once disassembled and closely examined, it had numerous cold solder joints. An 8 year old could have done a better job!
I took the module to work and using a microscope repaired all the crappy solder joints. I have not tried to reinstall it into the car to see if that was the issue. (Too busy driving it and having a BLAST! )

DELPHI uses **** poor relays and poor soldering techniques! GM needs to re-evaluate Delphi's quality control.

Hell, give it a try, what have you got to loose?

Wow, didn`t mean to start a war. Think I`ll send it out. Even if the problem is a ground or something, the module is going to go sooner or later. Might as well do it while I have the cash. Think I`m gonna send the climate control unit as well. $200 to fix both...can`t hardly go wrong. Thanks for the info. Now to find the instructions to remove both tumors!!

 

If I keep driving it til I get a chance to fix it, is there a way to stop the display from flashing the "service abs" message?

 

Push the RESET key on the DIC control panel.

I just noticed your from Baltimore. I was born and raised there. I lived in Dundalk. Went to Dundalk High. What part of Balto do you live in??

Until you get the module fixed, you stuck with the DTCs and DIC messages. Sorry, If you clear the messages bu pushing the RESET BUTTON, it will go away until you do the next ignition cycle. If you want to check the Grounds, look at G-101 and G-104/108

G-101 is aft of the drivers side headlight:





G-104/108 is next to the battery:



ALL Grounds:



Hope this helps and never be afraid to ask for help!

Steven! What are you doing up so late?? I agree Reset button will get rid of the messages. I posting minutes behind you.

Bill, small world. I live in Sparrows Point. My wife and her sister graduated from Dundalk. I just started talking to the guy who runs the corvette performance center on Philadelphia rd. Gonna have him check out my non functioning washer pump as well

 

Ah,,spent lots of time in Sparrows Point. Father owned a boat and we had it docked down there at Rudy's Marina. My dad and mom also worked at the steel mill for 35 years!

As for your washer pump, first check the instrument panel fuse center, Fuse # 10 (WSW) 25 amp. Most likely it is good if your wipers work. If it's just the pump, the button on the end of the stalk could be bad or the motor it self could be bad. Just remove the washer pump from the tank and either ohm it out or just attach 12 VDC to it to see if it runs.

Check the connector that plugs into the motor and the washer motor.

Oh by the way, the ground for that circuit is located at G-101 & G-201.

Hey,,,,G-101 is also associated with the EBTCM. LUCKY might be on to something!!!

Maybe a little luck for me. My grand father, father and father in law all worked there for a long time. That whole area by Rudys (lynhurst) is all houses now and Rudy`s was sold a few years ago. Haven`t been there since it changed hands. I`ll check out those grounds tomorrow.

 

Interesting. So the number of posts one has on the forum somehow elevates them to "God like" status. I'll have to remember that. Like I said, while it very well may be the EBTCM, there is a procedure to be absolutely sure. I'm not into "shotgunning parts", even if they are common failures. That train of thought works just fine if you have another part lying around, but if you don't and your dealing with someone else money/time/car, than I think it's better to take them through the steps. Moreover, if the OP goes through the entire procedure, and finds out its the EBTCM, then he has learned how to troubleshoot the system, and can help other members in the future.


Perhaps it's just because I have worked in an industry that is not tolerant of just changing parts. If I sent out a part for repair, having not troubleshoot the system to said component, and the got it back from repair finding that it did not fix the problem, I would be in a pickle. Now, I have to re-troubleshoot the system, costing the company more time(not to mention the cost of sending a good part for repair) and do what I should have done in the first place. I just don't see how another hour of time is worth not being sure.

Sorry I stepped on your toes Bill, but I'd rather be thorough than make a mistake any day of the week.

 

Well, unfortunately I don`t own a shop manual yet, so I don`t know the troubleshooting proceedure. Is it posted on here. Hey, I`ll give it a shot. Whats the worse that can happen, I`ll learn something! Thanks for all the tips. Being new to the corvette world, I feel kinda stupid asking some of these questions. Thanks for taking the time to help.

 

There are no stupid questions. Keep asking, and keep learning. Get a service manual when you get a chance. In the interim, there is a wealth of info on this forum to guide you.

 

Well, just took G101 apart. everything was very clean. Cleaned it anyway to be sure, and still same problem.

 

i second that

 

Hmmmm. So, you would rather just have someone tell you to change a part on your car, than cover all the bases to make sure it's bad. Ok, well..... I guess to each his own. I just like knowning what's in the kool aid before I drink it.

 

Lucky131969,

Don’t even think about going up against Bill. He knows what he is talking about and has helped more people on the forum with electrical problems then you can imagine. Besides, he also builds atomic bombs.

Yes, you are right I just feel sorry for the poor bas--rd that owns that black 1998 now, hope everything was put back in the right place



the evidence

 

I will certainly keep that in mind LV Vette. I had know idea I was guiding the OP down the wrong path......until now. I feel......so........ashamed.
