Description:

ECU 000611.04 is set when the wiring of electronic injectors (valves 1 to 3) is detected to be shorted to ground. This can lead to inadequate fuel delivery, resulting in engine performance issues such as rough idling or failure to start.

Reaction:

The engine control unit may disable affected injectors to prevent erratic engine operation or further electrical damage.

Recommendations:

• Thorough Wiring Inspection: Examine the injector wiring closely for shorts to ground, focusing on insulation wear or damage.
• Correct Wiring Issues: Replace or repair any compromised wiring to eliminate grounding problems.
• Verify Injector Functionality: Ensure all injectors are operating correctly after repairs are made.
• Reset ECU: Clear diagnostic trouble codes and reset the ECU to ensure all systems are functioning as intended.

Note:

Maintaining electrical integrity in fuel injector circuits is crucial for reliable engine operation and to avoid potential misfires or power loss. Regular checks can help detect and resolve such issues early.
