SUBJECT:
ECM Reprogrammer procedure through VIDA
When using VIDA to perform the S or V 40 ECM Reprogrammer (VEMS) upgrade the method is somewhat different than VADIS.
After the ECM Reprogrammer procedure is started and before doing anything else write down and save the entire number that appears in the box labeled Engine Control Module P/N. This number will be required if the download attempt fails for any reason. This number is visible in the box after the car profile is entered and VIDA communicates with the ECM
If any of the part numbers shown are visible, the ECM already has the most recent software and does not require an upgrade:
NOTE:
BATTERY CHARGER MUST BE CONNECTED; VOLTAGE SHOULD BE MONITORED, AND SHOULD NOT EXCEED 14 VOLTS DURING THE DOWNLOAD. CHARGER SHOULD NEVER BE SET TO HIGH DURING A DOWNLOAD TO ANY VEHICLE.
After the ECM number is recorded, proceed with the ECM Reprogrammer download as usual. Please note that it is possible that the status bar may not fill in as the download progresses, instead only an hour glass will appear. This is normal do not exit from the download until the status bar does fill in and FINISHED appears in the dialog box. It may take several minutes for the ECM Reprogrammer download to finish.
If during the download, the process stops and/or you receive an "UNHANDLED EXCEPTION" error close all open windows until you are back at the desktop. Remove the key and disconnect the car from PC. Reconnect the car to the PC, turn the key on, restart the VIDA application then restart the ECM Reprogrammer process. When you are asked if the ECM part number is corrupt, say YES. Profile the car as usual then add the 13 digit ECM part number that was recorded in the beginning paragraph into the ECM part number box.
Continue with the ECM Reprogrammer download as usual, and please note that the status bar may not fill in as the download progresses, only an hour glass may appear. This is normal, do not exit from the download until the status bar fills in and FINISHED appears in the dialog box. This may take several minutes.
If you did not record the ECM part number as requested in the first paragraph, and you have received the message that the ECM part number is corrupt, access the ECM and record the part number from the label on it. Use the chart to find the correct part number to enter in the ECM part number box in VIDA shown.
