314-5453 Electronic Control Module
314-5455 Electronic Control Module
325-3316 Electronic Control Module
262-1408 Electronic Control Module For assistance with troubleshooting machines containing ECM part numbers: 172-9389 Electronic Control Module or 161-2355 Electronic Control Module , reference Service Magazine, SEPD0741 and Service Magazine, SEPD0754 for more detailed information.Make sure that the part number of the ECM, which will be used in the machine test procedure, is the correct service replacement.Description
This procedure is to use a new or previously used and blanked ECM to determine if a machine malfunction is caused by the ECM. The definition of "blank ECM" in this document applies to an ECM with no flash file installed.The ECM can be blanked by interrupting the flashing process on the machine or on a bench. The reason for blanking of an ECM is to remove software interlocks, which could prohibit an ECM from being flashed on the machine. Refer to "Blanking a machine ECM" steps described below.A new or fully functional used ECM can be utilized for the machine test procedure. There is no need for any special flash file, "ECM test mode", or wash file. The only required conditions are: use a blanked or new ECM, follow the ECM replacement instructions, and run the appropriate calibrations. In addition, as always, all safety steps must be followed as described in the Operation and Maintenance Manual for the machine which is being serviced.There may be an advantage to flash the ECM with proper flash file on a bench before the machine troubleshooting procedure is started. Flashing the ECM on a bench can avoid some potential machine or harness-related problems.When an ECM is flashed on a bench, use bypass harness 317-2652 Control Harness As (ECM-specific adapter for Main Harness) and 217-0113 Wiring Harness . Refer to Tool News published on 11July 2008 for more detailed information.Limitations when Using a Machine ECM for Machine Testing
The ECM, which will be used for the machine test procedure, should not have previously installed premium software features. Because, an ECM with installed premium software features can only be flashed with a flash file containing equivalent premium software. Therefore, using such an ECM for the machine test procedure is not recommended.When attempting to flash over an ECM with software that does not support equivalent premium features, the following pop-up from the WinFlash will indicate that the ECM cannot be flashed.

Machine Configuration Data
When the ECM is being used for the machine test procedure, it is critical to follow the ECM replacement procedure and restore the correct machine configuration data for the machine that is being serviced. That includes capturing the ECM replacement file before removing the suspect ECM from the machine.This step is important because the ECM used for the machine test procedure can contain some old configuration data leftover from a previously tested machine.Depending on the machine application, the leftover
