Introduction
This guide provides troubleshooting steps for a flashing ABS light issue in Toyota Prado vehicles. The ABS light illuminates during the self-check sequence but then begins to flash. Cycling the ignition sometimes clears the fault temporarily.
Problem
The ABS light illuminates during the self-check and then starts flashing. This can occur more frequently when the vehicle is cold or has been sitting for some time. When the ABS light is flashing, the ABS system is disabled.
