    D6N ECM fault no start

    I have a vague idea how to do this but honestly I'll take any instructions you're willing to give. TIA

    D6N ECM fault no start

    Well I've been crawling all over this thing, I think I've disconnected and inspected all of the main ECM plugs. The bolt on one of the connections was only finger tight but I still think it was tight enough to be making the proper connection. I've been testing the ohm reading on all of the CAN...

    D6N ECM fault no start

    Good afternoon, just jumped on this thread again as I have the dozer in the shop and have been digging into this some. I have not got very deep into it.And have not come to a conclusion on it. It looks a bit overwhelming trying to track this down with the amount of space You have to work with...

    D6N ECM fault no start

    Ok, It does sound like my only option at this point is to start tracing wiring. It still seems a bit perplexing that once running these codes never come back up. It would seem like if it's a faulty connection they would pop up occasionally?

    D6N ECM fault no start

    I have a D6N dozer serial number CAT00D6NJMG500913. Occasionally when I start it, it will crank but not fire. Acts like no fuel/dead ECM. So far if I cycle the key a few times it has always eventually started. It will flash a few codes while this is happening, but once it starts the codes go to...

    D6N hard shift reverse to forward

    I bought this dozer on an auction, and it's been shifting hard like this since I purchased it. It was shifting so hard, that whenever I would shift from reverse to forward I would brake to a complete stop and the deaccelerate completely before I shifted to forward, I replaced the temperature...

    D6N hard shift reverse to forward

    Serial number: CAT00D6NJMG500913 Oil type: Cat 8T-9572 SAE 30 Transmission and Drivetrain Oil (TDTO 30) Engine coolant temperature is typically around 180° f. I've been running it all day, torque converter outlet temperature is reading 175-180° f. Transmission temperature is reading 130-135°...

    D6N hard shift reverse to forward

    I have a D6N that shifts very hard from reverse to forward whether it's cold or hot. Cat mechanic did a transmission fill calibration, he had a difficult time getting the transmission oil hot enough for the computer to do the calibration. The required temperature is 167° f. Once he was able to...
