Cummins ISME 420 Software Update

🚚 Here we had a Foden running a Cummins ISME 420 engine with customer complaint of heavy fuel consumption.

πŸ”Œ A scan using our Cummins Insite tool showed no fault codes but did show us that The ECM software was 12 and a half years out of date. ECM upgraded from version 15 to version 21.

πŸ’· Vehicle road tested with customer and found heavy boost leak from front end. Further testing revealed large hole in the intercooler. Customer advised to have intercooler replaced.
