Hi Andrin,

Here are the wiring diagrams for the BUS circuities and the display itself. I would check fuse # 12 and #10 in the fuse panel on the left side of the dash, and the fuse # 11 and #8 in the same fuse panel.

Here is a guide to help and the fuse locations as well:

Check out the images (below). Please let us know what happens.

Thank you once more again for providing vital informations on the Suzuki I was working on. Finally solved the problem today of no acceleration, the was a short coming from the transmission module, on live data, both the throttle body and accelerator pedal open to 100% but after you start the car, the throttle body stay about 36%, so in disconnecting the transmission module, the engine responded normally.
