Help please!! Instrument cluster
Hi, I’m in the U.K. and imported a 17 GS, having some issues with my car and the corvette dealer in the U.K. is a million miles from me it is going there for software updates etc but not yet. In the mean time om
trying to get thing working.
So... my instrument cluster, I get no corvette welcome message when I power the car up it shows only the EML light then once started a few seconds later the lcd will power up but I’m getting no data, no rpms when running no fuel gauge nothing. Also a lost communication fault code regarding cluster and LIN bus communication codes??? I have just replaced my Bose amp as this was stolen in the docs before getting to me, I know this needs coding and it will be done at the dealership but could this affect my cluster from working.
Sorry for the huge message I am out in Florida in 6weeks and was going to buy a new cluster and bring one back but it’s a big gamble at $600 and I’d be shocked if a 5k mile car a cluster would fail.
I also believe there is a 5v data line? Just what I’ve been told but if anyone would have any wiring diagrams or advice I would be extremely grateful.
Thank you in advance for any help.
i have the fault codes if anyone requires them.

Hi, battery seems good, freshly charged and conditioned and cracks no problem at all, loads of life I’m just wondering where the cluster gets it data from? Because if I plug me reader in I can watch all of the data on a live feed that I should be getting through my cluster.

What are the fault codes?
From the schematic, there are two 12V power feeds to the instrument cluster. Check fuse#25(15A) and #51(5A), both located in the engine compartment fuse box. Fuse 51 is an unusual fuse, it has two 5A fuse elements in it, check both.
All the data displayed by the instrument cluster comes from the Engine Control module, thru the serial data bus of the vehicle. Many, if not all electronic modules in the car are also connected to this databus, including the Bose audio amplifier (located under the rear cargo floor). Perhaps the new Bose amp is corrupting the databus. Unplug the Bose amp and see if the instrument cluster works properly.
The other data feed and wake up control of the instrument cluster comes from the BCM (Body Control Module). Perhaps the BCM is not sending the power wake up mesage to the cluster, which I believe is what triggers the cluster welcome screen when a door is opened.

Hi buddy! thank you for your reply!
All fuses are ok, including the double fuse that you mention, the fault codes I’m getting are U0155, U0184, U0198, U1510, fault is the same with or without the amplifier fitted, BCM would make sense,but there’s a lot of lost commutation faults there and I’m out of my depth! So I really appreciate you taking the time to help! 👍😁

U0155 = Loss of Communication with Instrument Cluster
U0184 = Loss of Communication with Radio
U0198 = Loss of Communication with Telematics Interface Control Module (OnStar)
U1510 = Loss of Communication of LIN Bus (various modules)
Based on the above DTCs, I doubt your Instrument Cluster is the root of the problem....maybe your BCM or Serial Data Gateway module.
Is there anything plugged into your OBD-2 diagnostic port, located in the drivers side footwell, next to the hood latch lever?
When they stole your Bose Amp module, was there any damage to the wiring harness or connectors at the Bose Amp? Any other damage to the vehicle?
I am continuing explore the Service Manual/schematics for more info.

Hi, very sorry for the delay I thought I check to see if there were any new posts and for some reason my reply hasn’t been sent.
so a lot of the commutation faults would be there because I had strip the dash to get the cluster out that I’ve sent to a friend to check in his c7 to determine whether or not the cluster is at fault.
but now your mention the data module and bcm they do in fact sound more likely.
All the wiring seems good doesn’t seem to be any visual damage anywhere, is there anything else you can suggest or and wires to trace that would cause the cluster not show data.
orignally I was convinced it was the cluster because when you power any clocks up the analogue needles should normally do a sweep? Correct me if I’m wrong as I say I’m new to the Corvette’s.
Thanks again for your your time and sorry for the delay.

So, which DTC codes are due to the original problem, versus after you disconnected modules when you took the dash apart???
And, is there anything plugged into the OBD2 diagnostic port (next to the hood latch)?
Also, check that the connectors are properly seated into the Gateway module, located in the drivers side footwell, next to where the steering shaft passes through the firewall.

Thank you for your reply.
No nothing plugged in to odb plug, let me get the cluster back and I will erase all faults and start again.
This will probably be Wednesday at the earliest by the time I get them back. I will update the thread as soon as I get the car back together

With the ignition OFF, does the center LCD screen turn on when the radio power button is pushed?
I am confused. Was your radio module stolen too? (Why does it need recoding?)
The radio module is located in the passenger side footwell.

Hi, I’m Sat in the car now and the stereo won’t power up with ignition on or off, but it was coming on before I took the cluster out I guessing/hoping this will be working again once I get the cluster back in?
It’s the Bose amplifier in the boot that needs coding apparently. I have booked the car in with a corvette specialist 12th March.
I was just hoping to get a bit further on myself so I could at least get it ready for a IVA so I can register it here.

Cluster, amp and radio are all tied together and effects each other. You'll need the amp re flashed first then the cluster and possibly the radio or any module you have replaced. I bet you have no warning chimes.

Hi dale,
thank you for you input I really appreciate it.
that would make a lot of sense. I’ve booked the car in, there’s nothing more I can do with out the correct software.
Thank you all for your help and I’ll keep you posted.

Absolute legends! Wouldn’t get help like this of brits I know!!!
Thank you all for your help! I really really appreciate it, it’s an absolute ball ache to get people over here to do the work but I have found a specialist a few hours away and shes booked in to get sorted. Got everything crossed because I’m itching to get this beast out!!!
Getting very impatient now because all I can do is look at the car.... this has been going since August!!!! 🤣🤣
learning curve so next time I import anything I will know
what to do and what not to!!
Thank you all again so much and hopefully lll have some good news in a couple of weeks!!

It really sounds like the problem is in the amp. Hope you got the right one and then you are able to program it. I think that will sort things out for ya. If you were a million miles closer I would program it for you. I'm learning how to program these module on my own and just recently did my amp. Everything came to life then. Let us know how it turns out.
