Description:

This diagnostic trouble code, ECU 000612.04, is triggered when the circuit of injection valves 4 to 6 is shorted to ground. This can impair the electrical function of the injectors, potentially leading to engine misfires or reduced engine performance.

Reaction:

The ECU may shut down the affected injectors to protect the engine and prevent further electrical damage.

Recommendations:

• Inspect Wiring and Connectors: Examine the injector wiring for shorts to the vehicle’s frame or other grounded components.
• Test and Repair Electrical Circuits: Use electrical testing tools to pinpoint the location of the short and repair as necessary.
• Confirm Injector Operation: After repair, ensure that all injectors are operational and receiving the correct voltage.
• Clear Fault Codes and Reset ECU: Clear any related fault codes and reset the ECU to ensure all systems are functioning normally.

Note:

Maintaining the integrity of the injector’s electrical circuit is essential for optimal engine operation.
