have you had the ignition on for a long time ?radio on ect , a flat battery will cause lots of censor errors ,leave it till the morning and if they have gone you are good to go,i only know this as i ran the battery down by having the radio on and boot open and ignition on and had similar display messages , left it for half an hour and then the car started , went for drive to toyota and was told a that if it was damaged the car would just not let me drive it, they also said if i was worried to ring the AA and they would come out and read the the codes as it was a saturday afternoon ,so i went home parked up rang AA an hour later they turned up i went out started car and guess what no errors as the car checks itself and found no problems, apparently these motors only have little starter battery's, not had any problems since so hope it is something simples
