If you’re working on a John Deere skid steer repair it probably didn’t take you long to notice that these machines have Yanmar engines. These engines do not use the proprietary Yanmar data link to communicate. Instead, they use the standard 9-Pin typical of other John Deere equipment.
By using the John Deere Diesel Laptop Kit we are able to easily connect to look at fault codes, view around 120 parameters, diagnose them with the correct repair information and run many bi-directional commands including:
* Perform Regens
* Code Injectors
* Code the DPF
* & Much more!
Derates on John Deere Skid Steers
Anytime a Yanmar engine, like the one found in John Deere Skid Steers, has an extremely high soot load fault it will throw a derate fault code for “Backup Mode”. This is a derated condition. In order to correct this issue the first step of the procedure is to run a “Recovery Regen”. During this recovery regen you may notice after an hour the machine stops the regeneration. This means it is not going to clean the filter and we need to replace it.
With the Diesel Laptop Diagnostic Kit we are able to run all four types of regenerations associated with Yanmar engines and code the DPF or let the ECM know you have cleaned it. Of course, if you were having a high soot load we need to investigate what caused the issue. This may be due to a bad injector.
