ISSUE

When attempting to complete the "Replace ECU" or "Update ECU" application on the Image Processor Module B (IPMB) the application fails with the message "No response from ECU".

After this fault occurs, the module does not report any software part and the system is inoperative.

CAUSE

After PATHFINDER requests a "Flash Erase" routine to be completed the module reports an error, this is because the module does not have enough time to respond.
