Terex TA35 (Serial #A7761012) Machine throttle intermittently cuts out. The throttle will not come back until key is cycled off and back on. Diagnostic Link and Machine Dashboard will not read wheel speed. When the problem exists, the dash will flash code number 54 for a wheel speed irregularity. Things that have been done: - Throttle pedal position sensor was replaced twice - Engine speed sensor was replaced - Output speed sensor was replaced - All wiring from Output Speed Sensor to TCU test good. - All wiring from TCU to ECU test good. Not sure where to go from here, but any advice or resources will be greatly appreciated!
Was the wiring tested under load with for example a 5 or 10 amp bulb to ensure it could handle load like after 10 to 20 minutes. Once wiring gets warm it can easily fail if it is compromised somehow. Just for info, a 10 gauge wire can handle 50 amps all day at minus 30- 40C , but can only handle 30 amps inside a hot engine area. Just something to be mindful of. Simon C
I have not yet load tested the wiring, I will absolutely do that and see what happens. Thanks for the reply
