So,,,analyzing everthing that your telling me,,,,lets try this. Open BOTH doors. Find the rubber accordion tube between the door and door frame. Pop the tube out of the door and door frame (is easy) and fish out the TWO connectors fo the door wireing harnesses out the door frame.





seperate the connectors, inspect, clean and repair as necessary. Look for bare wires and seal as necessary See if that helps.

Im having this same issue as VetteDawg, i found the first connector had a bare wire on each side (of course the one with the clear cover), i wrapped either side with electrical tape, so if that doesn't work i'll have to check the second connection. Its tight quarters working in between the doors, if the tape doesnt work can anyone recommend a better method for sealing off that wire? Perhaps some well placed silicon or something like that?

Thanks,
Alex

 

thanks Bill for the suggestion. I just tried that to no avail, any other suggestions are greatly appreciated. I'm not so concerned w/ windows, but if you think that could cause it to not start after 20 mins...

Some of the error code's might have been helpful in my previous post-- P0418,C1214,B2282,b2283,b3384,b2285,b226 ,b2264,b2605,u1215.

Most of those code are "H" except P0418, C1214 are current codes.

 

Right next to the BCM (to the left of it) are TWO skinny Grey connectors. Those are the STAR serial buss connectors. All of the modules communications combine here.

Find the one that has the least amount of wires in it. There should be four wires in the correct one. The top of the connector is actually a shorting bus. Pull the TOP of the connector off and then see if that corrects your issue.

NOTE. This will temporally disable your remote door functions (windows,locks etc) and the seat remote functions (memory movement). With that portion of the serial buss disconnected, see if that helps. Once you finish the test, reconnect the STAR connector and clear those codes that disconnection the star buss caused.

Bill

 

still no crank after 20 mins. dis/reconnect batt and fine for another 20.

just an observation, but it appears as though the previous owner spliced into the BCM wiring, jumped some wires together (still that way) and all sorts of whackiness. i checked a few and they were soldered, then elec. taped. Since it's run for past year that i've owned it, I would assume it's correct.

 

Please post some pictures of the butchered area.

BC

 

The first image is of the pink connector that mounts to the end of the BCM. The light green wire (held back by thumb) is connecting the bk/wh and gr/wh wires as well as that dark green (from under dash.)


The middle connector is in the next picture and has a red wire (from under dash) spliced into the light blue wire (sand paper is for contrast.)


Another observation, when I reconnected the BCM, interior lights lit up and car started without having to disconnect the battery (oops, I left battery connected throughout dis/reconnecting BCM, dunno if that hurts anything) 20+ mins later, no crank.

 

Holy Crap

The person who BUTCHERED the BCM wires needs an *** kicking. Find out where the spliced in wires go and see if they can be removed.

Get the connections back to as close to OEM as possible and see where you stand. YES there are some BCM issue that discribe what your expierencing. Get the wires sorted out before you replace the BCM.

Read with interest EVERY post on here about the vast electrical issues with our cars yet never ran across anyone having the high voltage issue I do.Displays Traction control,anti-lock,air bag,high voltage, headlights flicker. Been thru the grounds, door jamb repairs as noted so well by Bill here on this forum. Sent car to "stealership" for help and was told it needed an alternator for $800.00. Ran like hell and paid the $128.00 diagnostic fee to get my car back. Changed the alt to no avail.Thinking the ign switch might be the issue as the bcm(or whatever tells alt how much to charge) is seeing a lower voltage than the alt is really putting out. Had a Suburban overcharge one time and the voltage signal to regulator was way lower than the battery voltage. Any ideas? Car is a 2004 roadster with no mods at all! Thanks. New member Mike Hayden

 

Mike

Do you have an DTCs associated with the high voltage warning???

With the engine running:

Get a digital volt meter and read the battery voltage directly on the battery terminals. Note that reading.

What reading do you note on the Dash Volt meter and DIC digital voltage reading Note those readings.

Then read the terminal on the back of the alternator (BATT Terminal) under the rubber boot to ground. Note that reading.

The two reading should be very close to each other. The goal is for the readings to be the same. Then read the positive battery terminal to the alternator BATT Terminal. Note that reading.

The reading from the positive battery terminal to the alternator BATT Terminal should be ZERO or very close to it. The wire from the BATT terminal goes to the starter solenoid and from there it goes to the battery terminal. If that reading is high, you have a BAD connection between the the positive battery terminal and the alternator BATT Terminal



Next. Pin D (small red wire) in the plug on the alternator also goes to the starter. Read that voltage to ground. It also should read battery voltage. If there are major differences between these test points,, there are bad /compromised connections in that wiring run (most likely at the starter solenoid.

If the Pin D (small red wire) reads low, it could cause the alternator to output a higher than normal voltage.

Please post the readings that you get.

BC

 

Checked for codes with a Snap-on scanner and got no codes in engine section and only a high voltage code in the abs section. Voltage reads normal till the dash goes crazy, then it bounces around between 13.0 and 18. Went for a drive yesterday(Saturday) and all was well for 5 miles or so then it went crazy, got to my destination and shut car off for 20 minutes and came back and started up and all was well again. Drove home with no issues. (The car always drives well when this happens, no power loss or miss or anything).I do not have access to anything but the Snap-on scanner with OBD 2 generic setting because the cartridge only goes up to 2001. Will check voltages as instructed later today and report. I did look at the starter wiring during my inspection and noticed the wiring at pos post was tight but the whole post could be wiggled a little. No other issues. I can draw the battery down with a load tester and get 100 amps plus output from the alt with no heat at that connection so ruled out any problem there. I have a full shop at my house with 3 racks and good test equipment. I will report back. Thanks for your help here. And another question I have is I want to know what tells the alt how much to charge? Seems the alt is controlled by one of the computers and not internally like the alts I put on the rods I build. If so is the voltage adjustable somehow? Mike 949-690-4995

 

Have you pulled the battery and checked the wiring beneath it for damage? Battery acid leaks are sometimes a problem and while this is a long shot, it's worth taking a look because the loose terminal needs to be addressed anyway.

Do you realize that you can pull and read the codes without a scanner??

READING YOUR Engine Diagnostic Codes (DTCs)

The Diagnostic Display Mode is entered with the following procedure:
1) Turn on the ignition but don't start the engine.
2) Press the RESET button to turn off any warning messages. (i.e. door open, trunk open etc…)
3) Press and hold OPTIONS
4) While holding OPTIONS, press FUEL four times within a 10-second period.

Initially, on-board diagnostics go into an Automatic Mode which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each. ( i.e. PCM = 4 codes)
If none are present in a given module, you will see No More Codes on the display.
There are two kinds of diagnostic codes, Current and History designated with a letter suffix, C or ;H. A current code indicates a malfunction is present in the module displaying data. A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes.
More likely it's an indication of an intermittent malfunction.
Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.
Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except E/M. Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present;
press GAGES to go forward or FUEL to go back.
To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press RESET
To reset the codes once in manual mode, press and hold RESET until it displays NO CODES Press OPTIONS to go to the next module. Repeat the steps until you have reset the codes in all the computer modules.
NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles.
Once you have the codes, the next question is: What to do with the information?
First, consult the factory service manual. Any serious C5 Do-It-Yourself owner should invest in the Corvette Service Manual of the appropriate model year. The Service Manual is really a requirement if you want to understand and work on your C5.

Here is very good site of DTC definitions:


http://www.gearchatter.com


Make sure to include the H or C suffix!!

 

too the words right outa my mouth! of course i learned them from you!

Bill is the Main Man!

G/L

 

Man...why do I feel so stupid? This is killing me! Just for sh**s and giggles I pulled the DTS'S from my wifes 2001 convert (operates perfectly)as instructed and got a long list. Cleared them and went to the gearchatter site and none of the numbers were there. My codes were like "B0516H" and all thier codes were "P" prefixed. Checked the other years and didn't find any with the "B" prefix. Will head down to the shop after work and pull DTS's from the 2004. Do I need to get the manual to get the DTS descriptions? Will one manual cover both 2001 and 2004? Mike

 

There can be a number of reasons why a c5 will set a DTC. If there history, clear them and monitor. If they continue to come back,,,investigate.

There are code differences from year to year but,,,this list should be pretty complete. Something as simple as a low battery can cause codes to pop. Just disconnecting and reconnecting the battery will set DTCs

BC

 

I checked my 01 against the list and got battery circuits...no biggie. However there were several codes that started with "U". I got U1255H,U1064H,U1016H,U1096H all in the LDCM section. Got U2285H,U1255H,U1016H,U1096H in the RDCM section. Car runs fine, no issues. Cleared it and will check it again soon.
Equipped with my new knowledge,(dangerous I know) I checked my friends 97. He has tons of codes...3 current. B0502 rh drl relay circuit, B0507HC lh drl relay circuit, and B2482HC back up lamp relay circuit. Will ck the BU lights but not sure of the others. Guesing door locks. He did the door jamb repair as explained here. Will check the 2004 in a few minutes and report.
And Bill, I hope you didn't have to type all those codes...that would have taken me all day! Thanks for your help! Mike

 

Mike

I typed EVERYONE of them! I have blisters. Na,,,PDF files are great!

"I checked my 01 against the list and got battery circuits...no biggie."

Battery codes are a big deal. Please LIST those DTCs.

Bill

 

In the 2001 I got the "U" codes previously mentioned and B2282,2283,2284,2285. All battery codes. Figured since it runs perfect must be nothing. Any info on the U codes. All three cars I checked had these. Mike
