GSM replacement using a used part
I have been called to this shop twice now regarding this 2010 Jaguar XF 4.2L. The electronic gear shift module has been replaced twice with used parts. I have attempted both times to “Configure Existing Module“ using Landrover/Jaguar SDD and receive errors. During the process it shows unknown for the software number before the process begins. I have very little experience with Jaguars. I advised the customer to replace the GSM with the exact part number as the original, but I am asking for advice from someone who knows more than me about these vehicles. I don’t want to keep charging my customer every time I have to implement OE software and get nothing accomplished. I will try to add a screenshot of SDD shortly. I am posting This from my phone and need to get my laptop in order to do so. As of right now I have told my customer twice that it looks like he has the wrong part. The car shifts fine it just sets faults And displays “transmission fault”, and “parking brake fault” in the cluster display.
Ben, So first I always recommend replacement modules to be new when available, but if you are going to take the chance, then you will find at time as you work through SDD programming the screen after the first module check may give you a message with update available, or it will say unknown with a black dot or yellow icon, dont worry and push forward. The next part is of the programming event…
I did have a yellow icon with “unknown”. I ignored and tried to program it anyways. It failed. I advised the customer that I thought it was the wrong part for the vehicle.
It is very possible, best to get a new module from the dealer.
