Symptoms

  • One or more suspension/chassis warning lights are illuminated
  • Complete disabling of the Active Chassis Control system
  • Significant deterioration in ride and handling
  • The suspension is fixed in a hard or soft position without the possibility of adjustment
  • Possible knocking or vibration from non-working actuators

Causes

  • Simultaneous failure of several landing gear system actuators
  • Loss of power to the actuator bus (blown fuse, relay)
  • Short circuit in the common power supply circuit of the actuators
  • Internal failure or failure of the chassis control unit
  • Lost communication via CAN bus between the control unit and actuators

How to Fix

  1. Read all fault codes - C2300 is often accompanied by more specific codes for each actuator
  2. Check the fuses and relays of the chassis system actuator circuit
  3. Measure the supply voltage at the connectors of each actuator
  4. Check the grounding of the chassis control unit and actuators
  5. Diagnose the CAN bus for communication errors
  6. Sequentially check each actuator for functionality
