Code: 000109.18

Shortcode: 109.18

Description:

This code, ECU 000109.18, indicates a moderate deviation of coolant pressure from the desired range. Such a condition can indicate more significant issues like a failing coolant pump, substantial leaks, or blockages in the coolant system.

Reaction:

Moderate drops in coolant pressure can lead to inadequate cooling of the engine, which might increase the risk of overheating and engine damage.

Recommendations:

  • Comprehensive System Inspection: Thoroughly inspect all components of the coolant system, including the radiator, hoses, and pump.
  • Pressure Test for Diagnosis: Conduct a detailed pressure test to identify any drop in pressure and pinpoint leaks or faults.
  • Resolve Cooling System Issues: Repair or replace any defective parts found during the inspection.
  • System Reevaluation Post-Repair: After making necessary repairs, reevaluate the entire cooling system to ensure it meets the operational specifications.

Note:

Preventative maintenance and early detection of symptoms can significantly reduce the risk of engine overheating and related failures.
