Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
More than likely you have a bad instrument cluster but to be sure you need a scan tool to check for codes and also to do a gauge sweep test and indicator light test. But I believe replacing the cluster will only fix some of your problems but to be sure you'll need all the codes read with a scan tool. Thanks
Cool and thanks for the reply. If you have a genisys scanner please a accept a live call so I can help walk you thru this because maybe some thing is wrong with truck communication system.
No problem. At the DLC key off you should have less than 5 ohms between 4 and ground and 5 and ground, you should have power between 16 and 4 and 16 and 5. Between terminal 1 you should have a toggling voltage between terminal 4 and 2 between 0 and 7 volts DC.
It's possible that the reason the cluster isn't working because the readings at the DLC so I'd focus on getting the scanner to communicate first then diagnose the cluster. Even though I'm able I'm going to open your question back up so some other guys can help you get it fixed. Thanks
Hello, do you still need some help with this?
Is it the 2 or 4wd and what's the 8th VIN character? ALso have you verified the scanner works on another vehicle?
Thanks, ***** ***** double check your readings against this trouble tree to begin
16 should be 12v 5 should have continuity to ground. Is there 00-5 ohms between 5 and a good ground? I'll post diagram below.
Yes, the dash and dlc share a ground if I remember correctly.
