    Genie Z-45XC Boom Lift No Crank No Start error code 7617

    Thank you so much for that information. It was only that code about it needing calibration. Guess we will need the software as well cause doing it as per the manual, we are not hearing the beep it says it needs to make.

    Thanks for the response. I was not at work the day the guys came to hook up the pressure gauge to say that it was the converter that is losing pressure. Apparently they did not specify if it was the lock up or back pressure. The thing is, the truck is still running without any issues so far.

    Due to the adapter for the scan tool taking a while to come, we had someone come to test the pressure of the transmission and it turns out that the converter was losing its pressure.

    I will attach the TCU info. I wasn't able to get a scanner as yet to pull the codes. Should be getting one later this week. So if it is the output speed signal, the entire transmission has to be taken out to get access to it?

    Doosan DA30 with ZF 8EP 320 Transmission goes into neutral whiles driving.

    So something is telling the tcm to go into neutral while driving. I've already checked from the gear shift and everything is good from that end to the vc3. I will check the wiring from the vc3 to the tcm and transmission. Is there anything else that can cause the transmission to go into neutral...

    Alright I will have to raise the cab and check the wires to the transmission. Is the neutral power from the gear shift converted over to can bus data to the tcm?

    Yes, swapped gear shift, tcm and even ecm and still getting the same neutralising during driving. Even swapped the vc3 lol

    It just drops into neutral like that. No bumps are anything like that to cause it to. Even when you have it in manual mode, it goes into neutral. At first the operator thought that when it reaches 4th and higher gears, it goes into neutral but it does it in all the gears. Had a meter hooked up...

    Thanks for the response. I checked the wires from the gear selector to the VCU3 box and they are all good. Is there another way it could get a neutral signal?

    Yeah I recall they have specific codes for almost everything. So the problem came back again. This time it has a transmission error code that doesn't stay on for long, SPN 523650 FMI 0 OC 31

    Thank you guys also for your input. Oh so that is why it would affect the transmission. Though the funny thing is, we have another truck that has the same exhaust error code and it drives without any issue. Then again that one actuator wires weren't damaged by the heat.

    The ECM was not exchanged but the TCM was exchanged to see if that was causing the issue but it did the same with the other TCM. So checked the exhaust brake actuator and the wires were damaged from the heat. Repaired the damaged wires and it stop doing that. I honestly cannot understand how...

    Sadly we do not access to those at the moment to get the readouts

    Yes there was a fault code for the exhaust brakes being out of calibration. How can I go about to get the fault memory of the tcu without a scanner?
