Trouble Codes After Stage Reflash
It is possible to get a “false†trouble code, such as PO603, after reflashing a
Stage calibration into a Delphi ECM (2001 and later Softail, 2002 Touring).
If you encounter this situation:
Turn ignition OFF – this will move the code to “historicâ€.
Turn ignition ON and clear the code.
Turn ignition OFF for 10 seconds and the “false†code will be gone.
