Hello,

I have a Toyota 120XR (2019 model) that works fine but the customer keeps complaining of a flashing error code.

The red warning triangle displays and a code 5-0h displays on the screen, then the screen reverts back to battery percentage. The screen constantly flashes from error code to battery as soon as the truck is switched on.

Does anyone have a service manual or a list of codes that they wish to share please, or any help would be gratefully received.

Thanks Andrew
