How to diagnose and program B family excavators like 320B,330B by caterpillar ET. they have five pin service connector. thanks
U can't use ET on B series
so what can I use
Monitor
my question is how to program a new engine / pump ecm. I want to replace a faulty ecm and the new comes unprogrammed
Ecm on b series is always programmed Whats your serial number ?
thanks for your reply. machine serial number : 9HN00590
Do u have a part number of the ECM ? Is it a 330B u working on ? If yes they don't have engine ECM .
I am replacing this control 164-8255
I am just curios as to WHY you are replacing the controller on a 330B ?
there is no power going to the swing solenoid. checked the wiring and I put another ecm from another machine, it works fine.
Plug and play just need to do two calibrations
how?
how ?
Like this ……….. see Steps 9 & 10 below.
I just did it on the 312b but I couldn't for the life of me remember what they where for.
I tried to calibrate but the monitor not allowing me to enter to service mode by pressing the three switches simultaneously ( fine control, user and alarm cancel switches? but do you think calibrating governor and proportional reducing valve will fix the swing problem. it is 0 volt for the swing solenoid at the controller. thanks
Calibrating won't correct "swing issue". You said controller from another machine solved it. So, you're now telling us it's a controller issue, yet, your new controller doesn't output voltage. Are you in fine swing mode? I can't recall, but is there a swing brake switch to leave the brake off on B machines? Could you have inadvertently rocked the switch?
when I install ecm of the other machine I don't touch any switch. swing works fine. I don't think so because of some switches or some settings.
