Common Issues & Fixes

DEF System Faults or Derates: Caused by aged DEF or crystallization at the injector—use only fresh ISO-certified DEF and clean DEF lines and tank screen regularly.

Cab Display or Sensor Fault Codes: Loose wiring behind the operator display or corroded CAN connectors—reseat and clean terminals with dielectric grease.

Transmission Hesitation: Software-related shift logic issues—update TCU firmware and inspect pressure solenoids.

Hydraulic Drift or Slow Response: Often due to worn rod seals or contaminated hydraulic oil—replace cylinder seals and change filters.

Coolant Temperature Spikes: Caused by blocked radiator fins or weak fan clutch—inspect and clean cooling stack thoroughly.

Ride Control Not Engaging: Check solenoid control wiring and pressure switch calibration—adjust settings via in-cab display.
