If you want to convert your Toyota Hiace van (but this applies to all vans; the issue is the same for all), follow the advice in this video. Inside the cargo area, there is a wheel arch bulge that should not be covered but made "passable" by creating a continuous and rigid floor that gradually goes over it. The goal is to have only a small height difference that is easy to manage.

Measure the maximum height of the bulge from the metal floor, decide on the desired final height of the floor: usually, it should be flush or slightly above the seat rails. The difference between these two measurements will tell you the total thickness of the floor package (structure + insulation + underlay).

Create a frame around the bulge, then build a network of wooden cross members that span the protrusion; these will not all be at the same height, but those near the bulge will be higher, while those further away will be lower. The aim is to create a sloping surface.

In the spaces between the cross members, insert insulation panels; seal everything with specific tape and fix the first layer of underlay above the structure, and the bulge will already be significantly mitigated; for perfect levelling, add a second layer of insulation.

How to Activate the Disabled TRC on the Toyota Yaris?

As the video clearly shows, disabling or activating the traction control (TRC or ESP) on the Toyota Yaris is very simple. By default, the traction system activates every time the vehicle is started. To disable it, simply press the button depicting a skidding car located in the centre of the vehicle where the controls are, such as the hazard lights and the radio, but near the handbrake. Once disabled, the TRC off light will illuminate on the dashboard. To reactivate it, just press the same button again.
