Hi MyanRagahis,

I mentioned pulling the "Short-pin" "TO-RESET" the Main body ECU Compu Network just in case your problem isn't as sever as mine was; after all, I lost my Speed-o-meter and the Tach-o-meter, as well as the instrument cluster, the Instrument panel, and EVERY (False) warning light was staying on!

This before the trouble spread through the CAN-bus network, and caused the alternator to shut down. It didn't cause any damage to anything, but the inconvenience was horrific to say the least! I realize that you can't drive the vehicle with the short-pin pulled, but don't know how many of these trucks have needed a simple ECU Master RESET!

I have the Tech-Stream cable cable set-up, but when the OBD-ll stops communicating the cable won't do you any good; which I've had happen as well! but there are ways to clear the DTC's without the Tech-stream cable tool; see below:

YouTube There are a TON of these you-tube vids that will show you the proper way of clearing DTC's w/o a scan tool! Just take note: The DLC3 is shaped like a this \__/ with the top part closed. Mine is up-side down like this: /___\ so my number 16 is in the upper left-hand corner and the #1 is at lower right-hand side.

It can be confusing if you're watching you-tube and there's is the opposite than yours; so be careful! Post again if you need any help; there's NOTHING that you will encounter that I haven't either been through or seen, lol!'Best to you',

rig, cheers!
