ECU 003720.16 – Calculated Ash Level Moderately High. John Deere System Advisory.
ECU 003720.16 (ECU 3720.16)
Code: 003720.16
Shortcode: 3720.16
Description:
This diagnostic code indicates that the calculated ash level in the Diesel Particulate Filter (DPF) is moderately higher than expected. Elevated ash levels can reduce the efficiency of the DPF and may necessitate more frequent maintenance.
Reaction:
The ECU may adjust regeneration strategies, limit engine performance, or issue warnings to prompt maintenance action, potentially impacting vehicle performance to manage ash levels.
Recommendations:
- Regular DPF Maintenance: Schedule routine maintenance to monitor and manage ash levels, including cleaning or replacing the DPF as necessary.
- Optimize Engine Operation: Ensure the engine is operating efficiently, with good fuel quality and proper combustion to minimize ash production.
- Manual DPF Cleaning: If the ash level is high, consider a manual cleaning or replacement of the DPF to restore its efficiency.
- Reset ECU and Monitor: After addressing the ash buildup, reset the ECU to clear the fault code and monitor the system to ensure ash levels remain within acceptable limits.
Note:
Regular maintenance and monitoring of the DPF are essential to prevent excessive ash accumulation, ensuring the effective operation of the emission control system and compliance with environmental regulations.
