During practice for the 6 Hours of Spa-Francorchamps, Nakajima collided heavily with the back of Oliver Jarvis's No. 8 Audi on the Kemmel Straight due to spray-impaired visibility and broke his back. He was not replaced by Kobayashi because the latter was unavailable, and Buemi and Davidson drove the No. 1 TS040 as a two-person entry. Starting in sixth place, they held fifth until Duval and di Grassi passed them; Conway and Sarrazin qualified in seventh. Both cars lacked the Audis' and Porsches' speed; the No. 2 car finished fifth, and the No. 1 car finished eighth with throttle and electrical problems. Nakajima was cleared by FIA medical delegate Jacques Tropenat to participate in the 24 Hours of Le Mans test day on 30 May, and was announced as taking part in the race four days later. In its three qualifying sessions, Sarrazin put the No. 2 car seventh; the No. 1 entry, driven by Nakajima, took eighth in the first session. None of Toyota's drivers improved their respective car's times in the later sessions.
