The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.Google+

Toyota Land Cruiser Check Engine Light Due to EVAP System
Toyota Land Cruiser Problem

My 2011 Landcruiser fails the EVAP test regularly. The dash lights up. 'Check VSC System' appears in the center display. The check engine light comes on, the stability control override light comes on and the 4LO light blinks.
My dealer has searched throughout the emissions system for a leak and keeps coming back to the gas cap, which has been replaced twice.

Same issue as listed. I have not been able to repair it yet.
