If you find value in my videos and want to support a small channel feel free to buy me a coffee! (or not..) www.buymeacoffee.com/markalafrer
Watched 3 times and didn’t see anything about PCM ground, I have a PCM code 1518 and many sources say it could be a ground issue, would you please post the location of PCM ground? Thank you and thanks for the great video, I’m saving this one.
Thanks for reviewing all grounding points.
Wuzup, bro! Big fan of the channel, no problem supporting it. You saved me alot of $$ and time.. would a bad ground cause the ac not to come on, already checked the fuses and relays. I'm stomped
Glad I found this video great video, I'm new to the C5 world I need more videos like this I'm having some issues electrically. Lol
Great video man saves me a lot of time trying to help these guys online haha
Thanks bro you saved me a lot of time
You were so close to the areas of the grounds I could not see what part of the car you were at. It would’ve helped if you would’ve had a laser pointer or a sharp flashlight beam to be more specific.
Dude. U just saved me so much time.
Should I add dielectric grease after i clean the surfaces, before I tighten them back up?
Thank you for reviewing these grounding locations. Ground location #3( G401) is actually best accessed by removing the rear drivers side tire. It is connected to the frame rail directly behind the tire.
I need to do an updated version of this video with better lighting & showing the points (I had the car torn apart about 3 times now). I'm glad it was helpful! 👍🤙
Which ground controls the button to release your tonneau cover on convertibles ?
Thank you so much. Been having problems with Gauge cluster, radio, and wipers. Going to clean the ground on Driver side foot panel. Just cleaned the four cowl drain bladders, and think my grounds may have gotten corroded.
Where exactly is it near the foot panel?
@@timothyandemerald If your looking for the ground, it's between the door jam and parking brake release. You have to remove the plastic cover that covers the bottom of the door opening and the inside cowl.
I've went through most all of those to troubleshoot my speedometer not responding. I bought the factory service manual. I also discovered my PCM is ungrounded in the process. Troubleshooting that I find S120 and G120 are where the PCM grounds. However, I cannot figure out where those points are... The FSM doesn't specify. Ug. Any help would be appreciated.
Thanks this was needed
Which ground controls the trunk lights?
Very useful video that no one else will do.
But very hard to see because so much in camera shadow doing it alone. Need a helper to hold light and point at splice pack with a dowel.
A bit too close, so hard to understand what part of frame I'm looking at.
On my C5, the problem was grounding between the frame and the splice block just as you say.
i mustve missed it but where does the throttle control module, pcm, and bcm ground to??
What could make the gauge lights turn off as soon as the motor is on? They turn on when I unlock the car and when I turn on the ignition they are still on. So they are working. But as soon as the motor starts they turn off. 🤔 They are off regardless of whether or not I have the headlights up, but they did turn off the first time when I touched that lever. Can't remember if I turned on the headlights or cruise control or what, but I heard a short quite "beep" sound and the gauge lights turned off. Since then I can't get them to turn on when the motor is running. 🤔 I just boight it the other week. The former owner said that the fog lights stopped working the last time he washed the car, and that it keeps blowing fuses since then. But for me, everything else has worked until now, including all lights, until this gauge lights issue occured suddenly. 🤔
When I press the brakes, the radio goes into dim mode as does the car. Any ideas which ground that would be?
4:22 I would like to find this ground point.. the side panel next to footrest would need to be removed to access it? Any info on how to remove that cover would be helpful.
Curious- Radio Shack? I haven't seen one in many years. Not even on line. Good video though for the 9 most common grounds of the 13 total ground points.
you're missing the ground points under the pass and driver side headers that go to the block. Ive had fuel pump issues when the driver side ground under the header ground wire was loose.
I have 2007 C6 base and can't find the grounding point for the left turn signal. HELP ! 🙏
FYI, there are actually 13 grounding points on the C5. The two behind the radiator on either side or plugs that need to be taken apart and cleaned also.
Absolutely. Plus there are two white ground wires on the back of the drivers side rear head. You have to remove the intake to get to it. Good video but still incomplete because they’re 13 grounds not 9.
He actually mentioned the problematic grounds the one on the head unless out in a field or hood off i dont think would ever require cleaning
@StardustAutomotive
Which ground is the one for hvac unit? 97 c5 dual climate control. My hvac unit display will sometimes just die out then randomly come back on. It’s been doing this for a bit but now seems like it won’t come back on at all even after an extended period of time. I replaced all hvac fuses just incase under the passenger seat. Any help would be really appreciated!
I Think i have two electrical issues, one being the fuel gauge always reads empty, i replaced the fuel pump a few months ago and still reads E, also my DIC does not light up, it did a few weeks ago for a brief period of time flickering on and off
Good video. The battery strap and the two in the back had some corrosion under the nuts. Cleaned them up and put a few drops of conductive oil on them.
Keep'em coming.
How about the battery (brand new OPTIMA) dying every 5-6 days?? Could one of these be the issue ? No other symptoms and it seems to charge as it will restart and if I start daily - it seems to be OK. Just do not have the time...
What ground is associated with throttle position sensors?
Did I miss where the Front lights ground too? Specifcally the driverside turn signal?
Same on c6s ?
It started with clicking noise, i replaced starter because battery is good 13.2 Volts. After installing the starter I, It turns over nicely, but won't start. And I have a shit storm of codes, LIGHTS; Check Eng, ABS and Traction Control. MESSAGES; 1. Reduce Engine Power 2. Check Tire Pressure 3. Service Engine Soon. 4. Low Fuel. When I went to look up codes; all of them 40-BCM NO COMM, 58-SDM NO COMM 60 IPC NO COMM. All of them NO Communication. I pulled ground the 4 smaller ground wires, cleaned and reattached cleaned all of the ground wires associated with this issue. My questions is could it be the ignition or the PCM or PCB?
Having the issues did you ever find out the problem and the fix?
I have tail light issues. Idk what to do. Brake light works but taillights don’t ugh.
Another issue I'm having with my 03 Z06 is that under WOT, my volt meter will drop and I will get a CEL and "Service Charging System." I've always suspected it was a bad ground 'somewhere,' but where to start? Suggestions?
Service Charging System DIC message normally refers to the alternator having to be replaced. Have you already tried that?
do you have an OEM alternator?
I started getting this message after replacing OEM alternator
@@joemorales4775 I did as well. I had to exchange the new alternator for a different new one and the issue went away.
Cool...
What about windshield wipers ground?
I fully charged my battery and my dash cluster lights flash on and off, and unable to start the car. Sometimes I take the key out about 3 or 4 times and then it’s back to normal. I found one ground strap on the drivers side from the frame to the engine block is green(oxidized) it can’t be helping. I am leaning to either a security issue or a bad ignition switch. Any advice you have I greatly appreciate it.
I’m having the same issue! Let me know if you fixed it please
Im having the same problem. Did yall find the problem
@@ninadawg99 it was the ignition switch. Replaced and now works flawlessly
@@nachosilva3777 I replaced the ignition switch. No issues anymore.
okay so my issue is randomly all the lights on the dash come on, all my guagues max out and fuel goes to zero. and all the digital warning texts scroll through...reduced power/low fuel/low coolant/traction control. etc etc. im not sure whats going on but if i restart the car it could be okay for a while, or it will happen when im driving. i cleaned all the grounds inside the hood already
I’m having the same issues did you ever find out what it was and what was the fix?
@@julianramirez153 nope just been dealing with it cause it drives fine when it happens. I'm leaning towards a bad bcm
@@WillCollins95what did it end up being I’m having this issue right now except my car won’t run
@@jay2x477 the ebcm I believe. I took the ground off of it and cleaned it all up and it all went away. But yeah definitely ebcm related. Don't have to replace but it's definitely annoying with all the warning lights. Really only messes ya if if you're selling the car.
Are these near or the same for a C6 2008
since the c5's had so many grounding issues the c6's came with the ground wires soldered to the frame to prevent the same issues but yes they should be in about the same Area
Could #5 be why me Speedo does not work?
If the rest of your cluster has power most likely not not unfortunately as they all run off the same ground. I read somewhere some time ago that the speedo's on these tend to go out. Throwing in a new one isn't terribly hard though.
my whole car shuts off and has to have a jump to turn back on, then it will shut off again after a few feet of driving. Ground problem?
Alternator? Ground cable from battery loose perhaps? It culd also be you need to sand down your grounds to get a better connection. Fuel pump maybe…
It could be ur security lock doing it..if u take out the battery for a good while it will have to relearn ur key..it will say take key off for 10 secs..sounds familiar
Hola happy Monday
Same to you man. 🤘👍
Thanks.…Should have used a laser pointer.
Yeah, I need to revisit this video with better production value. Good input.
What are those seats?
Amazon specials. I have a few videos on them in my library if you take a look. Not very expensive
I appreciate the effort, but it would've been better to use a laser pointer/flashlight. The locations you mentioned are very vague without a pointer. Nice try, though....
I just can’t get my c5 to start ... fuck me im going through tall the hoops
Check your vats
Went through the same issue a few months ago. The problem was in the ignition tumbler. The 'chip' in your key is actually a resistor. Take your key and measure on the ohm setting of your multimeter. There are 15 different keys for your Vette. Figure out the resistance your key is supplying to the VATS. The fix for me is pulling the VATS connector off the back of the ignition tumbler. I went to Radio Shack (yes, we still have 2 in New Jersey) and purchased 2 resistors that equalled the amount of resistance needed for the VATS. I soldered them together and 'plugged' them into the plug for the VATS harness and taped the shit out of it with electrical tape. Put the key in the ignition and it fired right up. Total cost of the fix was around $4. LOL
Heads up yall: I tried doing the "accordion jiggle" at first and it wasn't working for me. you need to pull the accordion out and to the side, and shake the fuck out of the cable itself and it should fix - at least temporarily
Show me don't tell me
Dont be afraid to break a nail
Dude don't you own a flashlight. It's like you filmed it in the dark
Can't find the one behind the plastic on the driver side kick. Well. That's because you're just reading the wiring diagram and not actually doing it. You've never actually seen these in real life, have you?
Take the plastic trim over the seat belt off and you can't miss it. It is a black box screwed to the frame. 👍👍
13 grounding points, not 9.
