ISSUE

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 InControl 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.
    • Many of the Diagnostic Trouble Codes (DTCs) relating to the InControl Touch Pro system are unreliable and may log when there is no fault with the vehicle.
    • The guided diagnostic checks for reliable DTCs.

CAUSE

Incomplete diagnosis of overall InControl Touch Pro system.

ACTION

If a fault is suspected in the InControl Touch Pro system or is reported by the customer then the Pathfinder guided diagnostic must be followed. This gives the most reliable route to a right first time repair. The diagnosis may include investigation of other linked systems and software.

Do not attempt to diagnose the InControl Touch Pro system using DTCs except as advised by the guided diagnostic. 

Please follow the Diagnostic Procedure below:

DIAGNOSTIC PROCEDURE

CAUTION: This procedure requires a minimum of Pathfinder 218 loaded or later.

  1. Connect the JLR approved battery support unit.
  2. Connect the JLR approved diagnostic equipment to the vehicle and begin a new session.
  3. Follow the JLR approved diagnostic equipment prompts.
  4. Select 'Guided Diagnostics'.
  5. Select 'Interior Electronic Features'.

  8. Follow all on-screen instruction.
  9. When all of the tasks are complete, exit the session.
  10. Disconnect the JLR approved diagnostic equipment and the JLR approved battery support unit.
NOTE:
  1. Warranty claims for In-Control Touch Pro system parts may be rejected if the guided diagnostic has not been correctly used.
  2. Do not follow LTB01108/JTB00593 until you have completed the steps above.
  3. LTB01108/JTB00593 also provides additional troubleshooting information where the vehicle software update has failed.
  4. Both of the above Technical Bulletins will be updated to include the diagnostic procedure above in the near future.
