Regarding the ABS, there should be a malfunction in the system and since it only comes on after a short driving distance, it most probably is caused by a wheel sensor. To be sure you need a scan to retrieve the Diagnostic Trouble Code ( DTC ). You can get it done free at your local Autozone outlet and get back with the exact DTC so that I can understand the problem and provide necessary assistnce.
