Programming allows you to update and reprogram ECMs based on part numbers . You can access the following Programming selections by selecting Programming from the TOC:
When Programming, please follow the appropriate connection set-up in the diagram below.
Note:
There are different connection methods depending on Diagnostic use or Reflash use for E-IDSS. In addition, there are connection methods for 24V system use and 12V system use. Please use the correct connection method dependent on usage.
Select the voltage which is appropriate for the voltage specified in the ECM specifications.
In order to protect the ECM and the IDSS Interface Device, when connecting the device, connect the power source last. When disconnecting the IDSS Device, disconnect the power source first.
Programming can also be accessed by selecting the Reflash Icon from the IDSS tool bar:
<-- (Reflash Icon)
To avoid programming failures, you should first clear all Diagnostic Trouble Codes in Diagnostic Mode before proceeding with a Programming event.
In order to access Programming your dealership will need to have permission from Isuzu Motors. If you have not been granted permission, you may request it by selecting the “Request Programming Permission” button. Please perform programming permission on a periodic basis.
Each Reflash Mode will now be explained.
Select this for normal situations. The current ECM Part Number is read from the connected ECM and it is possible to program (reflash) with the automatically searched latest compatible part number.
Select the ECM Condition:
• On the machine: When the ECM is part of the machine.
• Off the machine: When the ECM is not part of the machine; for example, on a desk.
Current ECM Part Number Confirmation
Next, confirm that the currently displayed ECM Part Number is correct.
Note: You may return to the previous screen or cancel the reflash process at any time by selecting the “Back” or “Cancel” buttons.
New ECM Part Number Search
Information is selected in order to search for the compatibility information for the ECM that will be reflashed. The information to be selected is as follows: Engine Model, Engine Type, OEM Name, Engine Serial Number.
Confirm New ECM Part Number
The new ECM Part Number will automatically be displayed from the current ECM Part Number information. When this is the new target ECM Part Number, please confirm that this information is correct by selecting the “Next” button, or select the check box and enter another interchangeable ECM Part Number.
ECM Part Number Reflash Confirmation
Before reflashing, you will be asked to confirm the Part Number to be programmed. If the displayed Part Number is incorrect, select the “Back” button to return to the previous screen or the “Exit” button to return to the main menu. Check the new ECM Part Number that is to be reflashed. If the displayed New Part Number is correct, select “Reflash with upward compatible information.” and press the “Next” button. When performing reflash to an upward compatible part number with accompanying hardware modification, select “Proceed to upward compatible with accompanying hardware modification.” If the displayed Part Number is correct, first choose if you would like to reflash with the displayed criteria or proceed to upward compatible information with hardware modification. Then select the “Next” button.
A pop-up notification will appear displaying the available file name that the new ECM part number will be reflashed with. To begin programming, select the “OK” button for reflash to begin. Select the “Cancel” button to not perform the reflash.
*Please do not perform any other operation on the same computer while reflash is in progress as this may cause a reflash error.
Reflash Processing

This is used when returning to an older type of part number for an accompanying hardware change. Please be sure to check the information from the machine manufacturer.
In Engine Replacement Mode, it is possible to create an ECM with an old ECM Part Number specification. This mode is primarily used when replacing the engine in order to reprogram the new ECM specification into an older specification requirement so that the correct ECM specification can be used on the machine.
If a Part Number cannot be found for the engine replacement you will receive the following pop-up message:
Please proceed with programming by following the on-screen instructions.
Update with any designated part number. A separate, special password is required for this.
Preparation
Enforce Update allows you to specify an arbitrary Part Number for an update. However, a special password is needed in order to access this function. Before proceeding, be advised to prepare a label for the new Part Number to attach to the ECM. Also, please check the new Part Number in advance.
Selection Menu
Select the ECM Condition:
