Description:

Error code ECU 001761.01 is triggered when the ECU detects an extremely low fluid level in the Diesel Exhaust Fluid (DEF) tank, which is crucial for maintaining emissions control in diesel engines.

Reaction:

The ECU may limit engine performance or initiate a shutdown procedure to comply with emissions regulations and prevent damage due to insufficient DEF levels.

Recommendations:

• Inspect DEF Tank: Check the DEF tank for leaks or damage that might cause fluid loss.
• Refill DEF Tank: Refill the DEF tank with the appropriate type and quality of diesel exhaust fluid.
• Check DEF System for Blockages or Faults: Inspect the DEF system for any blockages, faulty sensors, or pump issues that might interfere with fluid delivery.
• Reset DEF System Sensors: If the DEF level was correct but not detected, reset or replace the DEF tank level sensors.
• Reset ECU and Verify System Operation: After refilling the DEF and addressing any system issues, reset the ECU to clear the error code and ensure that the DEF system functions properly without triggering further alerts.

Note:

Maintaining a sufficient level of diesel exhaust fluid is essential for the proper function of emissions control systems in diesel engines. Regular checks of the DEF level and system integrity are critical to avoid emissions-related performance limitations.
