Increasing numbers of Infotainment Master Controller (IMC) and Infotainment Slave Controller (ISC) have been replaced where a repair could have been completed without replacing the module. Analysis by JLR and the supplier shows:
1. No fault with the hardware as the fault was in a different module or related to software
2. Pathfinder guided diagnostics were not used but would have helped to identify the correct repair
The Pathfinder guided diagnostics have been improved to include all known failure modes within the IMC and ISC plus the additional modules which make up the In-Control Touch Pro system. This means that when you run the guided diagnostic it will identify concerns that affect the IMC but where the root cause lies in another module or in software JLR regularly updates guided diagnostics based on market feedback and data analysis to ensure emerging concerns are captured.
