ECU 000656.13 – Cylinder No. 6 Electronic Injector QR Code Invalid. John Deere System Advisory.

ECU 000656.13 (ECU 656.13)

Code: 000656.13

Shortcode: 656.13

Description:

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.

Reaction:

The ECU may limit engine performance to prevent potential damage due to incorrect injector calibration, leading to reduced power and efficiency.

Recommendations:

  • Verify QR Code: Ensure that the correct QR Code is used for the injector in cylinder no. 6. Check the QR Code on the injector and compare it with the calibration data stored in the ECU.
  • Recalibrate Injector: Use the correct QR Code to recalibrate the injector using appropriate diagnostic tools to ensure accurate fuel delivery.
  • Check for Software Updates: Ensure that the ECU software is up-to-date to prevent compatibility issues with the injector calibration.
  • Reset ECU and Verify Operation: After recalibration, reset the ECU and perform tests to confirm that the injector is correctly calibrated and no further errors are detected.

Note:

Accurate injector calibration is essential for optimal engine performance and fuel efficiency. Proper QR Code entry during the calibration process is crucial to ensure the injector functions as intended.
