Error code ECU 000676.14 is triggered when the ECU detects that the cold start aid relay output voltage is high even though the ECU has not energized the relay. This indicates an unexpected activation of the cold start aid, which could be due to a wiring issue, a stuck relay, or unintended electrical interference.

This error code, ECU 000676.05, is set when the ECU detects no output signal from the glow plug relay despite energizing the relay supply lead. This condition indicates a circuit problem, such as an open circuit at the glow plug relay or a defective relay (K02/01). The ECU uses manifold air temperature to determine the…

Error code ECU 000676.03 is triggered when the ECU detects an output signal from the glow plug relay when it has not energized the relay supply. This indicates an unexpected high voltage in the glow plug relay circuit, which may be due to a wiring issue, a malfunctioning relay, or an unintended electrical path.

This error code, ECU 000656.13, is triggered when the ECU detects that an incorrect QR Code was calibrated into the ECU for the electronic injector in cylinder no. 6. Incorrect QR Codes can lead to improper injector calibration, resulting in inefficient fuel delivery and suboptimal engine performance.

John Deere error ECU codes
Error code ECU 000656.07 indicates that the ECU has detected a mechanical failure in the electronic injector for cylinder no. 6. This is identified by the lack of a drop in fuel rail pressure during the injection process, suggesting that the injector is not delivering fuel as expected. Mechanical issues can arise from blockages, internal…

Error code ECU 000656.06 is set when the ECU detects a short circuit in the electronic injector circuit for cylinder no. 6, resulting in resistance that is too low. This condition typically indicates a short to ground, which can cause the injector to malfunction, leading to misfires, inconsistent fuel delivery, and potential damage to the…
