The 08 index may be suspect because I'm too lazy to go downstairs and grab the computer with the diagnostics software on it. But I distinctly remember the GSM unit has index 16 -- and it does not conflict with coding indices from any other unit in the car.
Is this GSM TCU used or remanufactured? What diagnostic software is that?
