Speedometer remote start not working after incorrect jump start

Hello my name is Dave.

It sounds like the most likely problem is a blown fuse.

Here is a link to our tutorial on testing/replacing fuses:

I am also attaching diagrams showing the fuse locations with a list of their functions. Please keep us up to date on your progress and thank you for using 2CarPros!

First of all I want to thank you for your reply very generous of you thank you very much now, I checked all the fuses, all the fuses are good and working.
The only problem now is I do not know how to check the relays
That are in the fuse box can someone please help me with this.
Speedometer and associated equipment with that still does not work after the mechanics jump started my car from the battery which they should not have done in the first place.

I am not sure how this happened but it appears it may have taken out the circuit board of the cluster or the PCM. The speedometer is operated by the cluster taking the vehicle speed sensor from the PCM and displaying it. The fuel economy is just an average based on info from the IPC and PCM and the remote start has a lot of inhibit parameters from the IPC and PCM.

I would suggest starting with checking for codes. I am not sure how just jumping from the battery would cause this unless they hooked the cables up backwards. The reason is, when you use the auxiliary location and not directly to the battery they are just cables that run to a more convenient location which gives better access.

I would suggest starting with the codes and going from there. Thanks
