Hello and welcome to JustAnswer!

There are may thing that will cause the ESP and BAS lights to come on. The lights have come on because the ABS module has seen an issue somewhere in the system that will prevent proper operation and has set a fault code. The problem may be a wheel speed sensor issue, the yaw sensor, steering angle sensor, the hydraulic control unit or pump motor, the issue may be the ABS module itself.

The first step in diagnosing the problem will be to use a scan tool or code reader to see what fault codes have set in the ABS module and electrical testing will likely need to be done from there.

If traction control came on when it shouldn't have then I would first suspect an erratic wheel speed sensor signal.
