The Traction control system samples wheel speed from all 4 wheels and if it determines that the front wheels are turning faster than the rear wheels it engages the traction control functions. (ie pulsing the breaks, reducing fuel and adjusting timing) I would check the wiring very carefully and look for some damage to it or to the grounding points. You should be able to turn off the traction control system and have the car driveable until you can sort it out.

Couldn't find a C12248 (too many digits) code but here are all the ones related to TC:

C1221 LF Wheel Speed Sensor Input Signal is 0
C1222 RF Wheel Speed Sensor Input Signal is 0
C1223 LR Wheel Speed Sensor Input Signal is 0
C1224 RR Wheel Speed Sensor Input Signal is 0
C1225 RF Excessive Wheel Speed Variation
C1226 LF Excessive Wheel Speed Variation
C1227 LR Excessive Wheel Speed Variation
C1228 RR Excessive Wheel Speed Variation
C1232 LF Wheel Speed Circuit Open or Shorted
C1233 RF Wheel Speed Circuit Open or Shorted
C1234 LR Wheel Speed Circuit Open or Shorted
C1235 RR Wheel Speed Circuit Open or Shorted
