Rework Procedure

Show/hide table

Technician will need a laptop with latest version of CAT ET and a communications adaptor. This will require the ECM to be powered and factory passwords (reason code 1) will need to be generated.

After flashing the new software file 308-4227 to the engine ECM, new FLS / FTS values will need to be entered into the ECM based on the table below which references engine serial numbers and corresponding FLS / FTS values.
