I'm playing the Japanese version of Tomb Raider Legend for the Xbox 360, and I received an error upon driving my motorcycle up into the truck at what looks like the end of the first motorcycle area (the one after the Mexican-looking village). As soon as I drove into the back of the truck a little on the right side, the screen started to dim like it was going to a cutscene but suddenly went black with an error message that said the following:

Can't find signal732 in unit VehOne4.
Unit vehonehub1 is trying to hook up to it at signal706

Here is a photo I took of the error on my TV:

My controller stopped responding yet continued to vibrate.

Anyone know what this is?
