Question about Jeep Wrangler
Starting on page 23 of the owners manual explains the ESP/TCS (not BAS) waring light and what turns it on, I have copy and pasted that from the owners manual for your 2008 Wrangler, but in a nut shell it means a malfunction has occurred in the Traction control and electronic stability program, this is part of the ABS (anti lock brakes) system, there are many components that can cause this system to turn on the light and to find out which part or system is at fault the system must be tested by the dealer with a special Jeep electronic scanner to access the fault code(s) that are stored when this light stays on, if the light comes on and then goes of while u are moving that is normal and means the system is doing its job of controlling loss of traction at the tires such as a skid. here is the owners manual explanation as copied.

The light that shows a car with squigly lines behind it is ESP warning light, owing to a system permanent failure.
If ESP/ABS lights ON you do not have any ESP/ABS (Electronic Stability Program / Anti-lock Brake System) on the vehicle !!!
ESP electronic control unit (ESP ECU) includes ABS ECU, and can be accessed using a diagnostic scantool connected to the Data Link Connector (DLC) of the car. After ESP ECU memory scaning from internal errors, (Diagnostic Trouble Codes - DTC memored), you will be able to know exactly what piece is damaged. After bad piece replacing you will be able to erase the ESP ECU memory from internal faults, and reset ABS ECU = turn OFF the ABS brake light.
