== Location and access ==

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.

The TCU is located above the pedals.

The unit photographed below is not detected as a USB device when connected to a computer. It may be faulty, or in some kind of disabled mode, or a non-standard USB protocol, I am not sure.

In vehicles which have had an English conversion done by EVs Enhanced, the [[AV Control Unit]] may not function while the TCU is disconnected (complaining about a missing or invalid key file).
