Hello, I got a 1687, 1681, and 462. Where is fuel level sending unit located, and also the instrument cluster module, do you guys know much that would cost , and if so do you know cheap ones, dont have the money,

 

My instrument cluster it shows how mph im goin, rpm and how much gas i have. they do work but the ecm doesn't receive message from ccd bus, instrument cluster module, would that be poor connection?

 

The only code I see in my book is the 462. The fuel level sending unit is in the fuel tank. You need to drop the fuel tank to change it. The instrument cluster module is right in front of you (when you're in the driver's seat). Why do you want to change it?

I recently repaired an inoperative instrument cluster by disassembling it and soldering the pin connectors to the contacts. The design isn't very good, but soldering it fixed the indication problem.

 

P1687 No Cluster Bus Message, P1681 No I/P Cluster CCD/J1850 Messages Received. The instrument Cluster shows how much mph i'm goin, also shows how much rpm, and gas.
