2010 Silverado Instrument cluster issues

[getgoosed]

I have a 2010 Silverado 1500 LTZ with intermittent instrument cluster issues. Under normal driving, all of the gauges drop to zero and all of the warning lights come on (Service Air Bag, Service 4 Wheel Drive, Service Trailer Brake System, Park Assist Off). During a recent drive, this had occurred multiple times within 5 minutes going from fully functional to not. The climate control system also locks up and radio shuts down during the failure. When the gauges resume working, the radio comes back on, but the climate control sill not work until the truck is turned off and back on.

 

The dealer had hooked the truck up to a scan, but did not find any issues with it. They could not find any stored codes.

 

Any ideas of where to start looking?

 

thanks

Don't know what your warranty is like up there in the north country. Hope you still have some of it ....

 

Looks like a bad connection somewhere ... but WHERE in 100k km's of wiring ....

 

First check I'd do would be the battery connections, then any grounds you can see around the engine and frame .... after that ... ????

First place to start is the battery connections. Make sure the terminals and battery cables are clean and no corrosion.

The battery terminals are good, but I will check the grounding just to make sure. Is there a wiring harness somewhere that may be common to an area where are the sensors would be sending to the cluster? One thing the dealer did do was to remove the junction block and reseat it. After this, it did not occur for approx. 3000miles leading me to think it was a connection issue or corrosion of some sort.

have battery tested ,

 

as you can see ,there are no direct connection to any sensors ,,,,its all done by modules

I am also having the same problem in my truck, my gauges work sometimes and I am getting the service air bags on the notification screen. I have no clue what is wrong and I am guessing the dealership will be killing me if I take it in and have them try to find the problem.

air bag message means your SRS has a code in it and is DISABLED ,,,,,,,,,you have no SRS system while active code is present ,,,,do not use the truck ,take it in ,,,if you have a family ,,,no brainer

A late add to this thread...

 

I have taken the truck to a Chevy dealer where it was scanned. I had showed them the video of what was happening, but they were unable to reproduce the issue and the scan came up with nothing. The only thing that really was done was remove the under hood fuse box and reinserted. The issue had not occurred for quite some time after. Recently, the issue has occurred more frequent, but still unable to reproduce. The only time it seems to happen is after many short in town trips (less than 2k 3x daily) and then occurs within 50 to 100km of driving at hi way speeds and never at slow speeds.

 

This week while getting other work done at the dealer, they ran an avr test and found the battery and alternator to be in good order. Results are as follows:

 

10.8v under load

220amp output

Alternator 120amp

.006a parasitic draw

 

Yesterday on a highway trip, the issue occurred again. This time when slowing down to an approach the gauges, sensors and cabin controls turned back on. After seeing this, we didn't stop but continued, and immediately turned back off. At the next approach we stopped and turned off the vehicle... And it did not start. No clicking, hazard lights would not even turn on, but dash lights were on. After multiple attempts to start the vehicle, no joy. After the vehicle sat for around 5 minutes, the hazard lights started flashing and the truck started!

 

Today I used a snap-on micro vat battery tester and it initially showed charge and retest, but then pass a on further tests. It did show 720cca capacity.

 

I still am not 100% convinced that the battery is good on a 4 year old battery but I would think the tester is smarter than my hunch.

 

Anyone have any guess as to where next to look, what to test, or replace?

 

Thank you very much in advance.

To further the saga...

 

Right now the truck will not move again! A multimeter is showing 12.2to 12.54v fluctuating quite a bit. The key will not start the vehicle or turn off the factory theft alarm, remote fob does not function, and all sensor warnings are going off on the cluster.

 

Before my neighbours get pissed at hearing my alarm go off every time I tough the vehicle, does anyone have any suggestions??

 

Thanks

Check your negative battery cables, particularly on the frame in the engine bay.

Ok, will have to check in the morning. From what I recall looking at before they were good but I will definitely check. Is there a specific spot that you can think of that I should pay attention to?

[getgoosed]

Kinda sounds like this older thread may be very similar. Thoughts
