Had this happen twice with engine light ,vsc , traction control and 4wd lo flashing both times was due to low battery voltage. First time was a legitimate flat starter battery on Fraser Island the day we were leaving. I jump started engine did not loose power but lights stayed on until alternator put enough charge into battery by gympie we needed fuel restarted car after and all faults clear. Second time was a corroded they terminal some boiling water dissolved the buildup restarted car, all lights cleared immediately. I beleive one cause is low battery voltage and computer shuts down non essential electrics to focus all power to charging and the necessary running components. I have only made an assumption on this based on my experience hope it helps someone but logic says if they need 2 batteries to operate the thing standard, there must be a big drain on power system without any additional extras such as spots radios fridges ect. Ive got a 2010 landcruiser by the way. Hope it helps guys cheers
