Description:

This code, ECU 000611.03, occurs when the wiring of electronic injectors (specifically for valves 1 to 3) is found to be shorted to a power source, typically 12 volts. This electrical fault can cause uncontrolled injector operation, leading to engine misfires or over-fueling.

Reaction:

The ECU may limit engine power or activate other protective measures to prevent damage from uncontrolled fuel injection.

Recommendations:

• Inspect Injector Wiring: Check the wiring harness for damage or corrosion that might cause short circuits.
• Repair or Replace Wiring: Repair any damaged wiring or replace the harness if necessary to ensure proper electrical integrity.
• Test Injector Operation: After repairs, test the injector operation to ensure they are receiving correct voltage levels.
• Reset ECU and Clear Codes: Reset the ECU to clear the fault codes and restore normal injector control.

Note:

Proper maintenance of injector wiring is critical to prevent electrical faults and ensure consistent engine performance.
