1. 1

   Connect the CNH EASy diagnostic tool to verify the code and check for the underlying FPT engine code (DTC 171)

2. 2

   Thoroughly inspect the wiring harness leading to the Bank 1 fuel injectors for a short circuit on the high-side to the battery or a short to ground

3. 3

   Verify the injection signals at the harness connectors to rule out a wiring break or short

1. 1

   Repair or replace wiring

   If a short circuit to the battery or ground is found during the diagnostic checks of the Bank 1 injector harness, repair the damaged wiring or replace the injector harness.

2. 2

   Replace ECU

   If the wiring and injection signals test perfectly fine and no external short is found, the defect is an internal ECU problem. Replace the ECU.
