System

Sany LMI

Symptom

Load reading is erratic or "flashing" 0.0t.

Diagnosis & fix steps

Pressure Transducer Fault. LOGIC: E12 (Rod side) or E13 (Piston side). The LMI cannot calculate the "Moment" because it lost one of the two pressure inputs.

Red Seal field insights

These transducers are located on the main lift cylinder block. If you have E12/E13, swap the connectors between the two sensors. If the code changes from E12 to E13, the sensor is dead. If the code stays E12, the wiring harness is broken.
