We bought a used zx180 and it has two codes we wanting to address. They are 11458-02 and 11307-03. This machine has had a hammer on it for quite sometime also. 11307-03 says: Front Pilot Pressure Sensor Circuit High Input. 11458-02 says: (Auxiliary) Discontinuity of Selector Valve. Any insight on these would be greatly appreciated. Thanks in advance !
BTW.. Machine serial # is: 1FFDBD70KCE530014 The model is a zx180LC-5N
Looking up through the whole under the control valve towards the cab side, there is a solenoid valve (I think it is the one pictured below). The code you have says the solenoid is disconnected or not present. The pressure sensor is mounted on the swing motor. The code says the signal voltage is over 4.5 volts. So there is a short to power somewhere, or an open signal wire (if it is a pulldown circuit, I can't recall which it is). Try disconnecting that sensor to see if the code changes. Short the signal wire (center wire)(violet wire w/red tracer) to ground to see if it changes the code.
Will do MG. We sure appreciate your time and input. We will have machine in our possession next week and take a look. Again thank you and have a great weekend !
