1 u2360 control module communication failure

What it means:

Control Module Communication Failure

• P0300: Random/Multiple Cylinder Misfire Detected – This code indicates that the engine’s computer has detected random or multiple misfires in the engine cylinders.
• P0171: System Too Lean (Bank 1) – This code means that there is too much air and not enough fuel in the combustion chamber of Bank 1.
• P0420: Catalyst System Efficiency Below Threshold (Bank 1) – This code suggests that the catalytic converter is not functioning efficiently on Bank 1.

Common Causes:

Control Module Communication Failure – Common Causes:

• P0600: Serial Communication Link Malfunction
  • Faulty wiring or connectors
  • Defective control module
  • Network communication issues
• P0601: Internal Control Module Memory Check Sum Error
  • Corrupted memory in the control module
  • Failed control module
• P0602: Control Module Programming Error
  • Incorrect programming of the control module
  • Software update required
• P0603: Internal Control Module Keep Alive Memory (KAM) Error
  • Batteries disconnected recently
  • KAM circuit issues
• P0604: Internal Control Module Random Access Memory (RAM) Error
  • Control module hardware failure
  • >Corrupted RAM data in the control module>

    Common Misdiagnosis:

    html

    • OBD2 Code: U0100 – Lost Communication with ECM/PCM “A”
      
      Description: The control module has lost communication with the Engine Control Module (ECM) or Powertrain Control Module (PCM).
      
      Common Misdiagnosis: Replacing the ECM/PCM without checking for wiring issues or connector problems.
    • OBD2 Code: U0121 – Lost Communication with Anti-lock Brake System (ABS) Control Module
      
      Description: The control module has lost communication with the ABS control module.
      
      Common Misdiagnosis: Replacing the ABS module instead of addressing a faulty connection or damaged wiring.
    • OBD2 Code: U0155 – Lost Communication with Instrument Panel Cluster (IPC) Control Module
      
      Description: The control module has lost communication with the instrument panel cluster.
      
      Common Misdiagnosis: Assuming a defective IPC when the issue may be related to a poor ground or network problem.

    Common Diagnostic Steps:

    Control Module Communication Failure

    Common Diagnostic Steps:

    • Check for any other stored trouble codes that may indicate a specific issue with a particular module or circuit.
    • Inspect the wiring and connectors related to the control modules for signs of damage, corrosion, or disconnection.
    • Verify the integrity of the CAN bus network by checking resistance values using a multimeter.
    • Ensure all control modules are receiving proper power and ground signals.
    • Use an OBD2 scanner to attempt communication with each module individually to identify any non-responsive units.
    • If applicable, update the software or firmware of affected control modules as per manufacturer guidelines.
    • Consult vehicle-specific repair manuals for additional diagnostic procedures tailored to the make and model in question.

    Please note: These steps are general guidelines. Always refer to the vehicle’s service manual for precise instructions and safety information when diagnosing and repairing automotive issues.
