Why is both T/C and ABS Indicator Lights coming b on and staying on all of the time

The ONLY way to find out why the light is on is by having the ABS scan tested to determine the system fault .. There are several possibilities of which the most common is a failed wheel speed sensor or wiring to said sensor.. However the scan test IS required! .. Just so you'll know - ABS module also controls the T/C (Traction Control) system, that's why 'both' lights are on (by default) .. Once the ABS failure is *repaired*.. Both lights will turn OFF.
