DTC Eraser / Error Code Cleaner
Professional Standalone Recovery for Liebherr R-Series (ECU2-HD)
 
The Liebherr R-Series Error Code Cleaner is a specialised, standalone diagnostic tool designed for crawler excavators equipped with Tier 4 Final engines. Engineered for rapid trackside recovery, this tool communicates directly with the ECU2-HD Engine Control Unit, allowing you to clear critical faults without the need for a laptop or expensive diagnostic software.  When your Liebherr enters an "Inducement" state (SCR-related power reduction), every hour of downtime counts. This "Plug & Go" interface allows operators and fitters to reset the system and restore full engine torque in seconds.

Reset SCR Inducement: Automatically clears power reductions and "Limp Mode" restrictions caused by emissions faults.
