What to do When the Jaguar ECU Won’t Listen
This bulletin applies to Jaguar E-PACE, F-PACE, I-Pace and F-TYPE vehicles. When attempting to complete the PATHFINDER applications “Replace ECU” or “Update ECU” for the image processing module B (IPMB), there is an error message displayed “No response from ECU.”
After this fault occurs, the module does not report any software parts and the camera system is inoperative. When PATHFINDER attempts to erase the previous software from the module, it does not wait enough time for a response. This results in the user being displayed the error message “No response from ECU”.
