My 1995 Mystique equipped w/ ABS & T/C has been setting both lights when vehicle reachs 45mph. They will stay on until ignition turned off. ABS system functions under an ABS stop. Checked sensors and connections for any obvious causes. Hooked my Snap-On scanner to try and retrieve any DTC's but none were stored. Has just started to occur within the last 5 days when roads have been snow/wet/salt covered. Driving around town under 45mph I have not gotten the light to come on. Only when I reach highway speeds will the lights come on and stay on until I shut down. Has anybody had similar situation with these symptoms? If so, what was the solution and what sub-systems should I look further into. The vehicle only has 31K.
