	The TCU is located on the right-hand side of the vehicle in all models.		The TCU is located on the right-hand side of the vehicle in all models. It is attached to a metal bracket, which has the [[Around View Monitor Control Unit]] on the other side, if equipped. Once access is achieved, the entire bracket can be removed with the TCU, [[Around View Monitor Control Unit]] and wiring harness all still attached (there's a good amount of slack), and then once pulled forward the TCU can be disconnected.

Access is achieved by removing the panel above the pedals, then removing the lower instrument panel (the panel below the steering wheel, with the bonnet release latch and the panel of buttons (open charge door, etc). Refer to the service manual for more detail on removing this panel.
