Probably just needs a zero point calibration done. The below procedure is for 03-04, not sure if it's the same for newer models tho.

VSC LIGHT ON – DTC C1203 – BR005-03 December 4, 2003
Zero Point Calibration of Yaw Rate and Deceleration Sensors Using SST 09843–18040 <-- Nothing but a couple pieces of wire that you connect to the 2 terminals on the OBD2 plug under the dash. Need to be about 12" long each.
When having replaced the yaw rate sensor, deceleration sensor or the ECU, perform the process for zero point of yaw rate and deceleration sensors as shown below.
NOTE:
While performing the zero point procedure, do not tilt, move or shake the vehicle. The vehicle must remain in a stationary condition throughout the entire process. Do not
start the engine and be sure to perform the procedure on a level surface with an inclination of less than 1%.
1. Ensure the shift lever is in “P” range.
2. Turn the ignition switch ON.
3. Using SST 09843–18040 (wires described above), repeat a cycle of short and open between terminals Ts and CG of DLC3 4 times or more within 8 seconds. Verify that the VSC indicator light is lit indicating the recorded zero point is erased.
4. Turn the ignition switch OFF.
5. Be sure the terminals Ts and CG of DLC3 are disconnected.
6. Turn the ignition switch ON.
7. Check that the VSC warning light goes off about 15 seconds after the ignition switch is turned ON.
8. After ensuring that the VSC warning light remains OFF for 2 seconds, turn the ignition switch OFF.
9. Connect the terminal Ts and CG of DLC3 using SST 09843–18040.
10. Turn the ignition switch ON.
11. After turning the ignition switch ON, check that the VSC warning light is lit for about 4 seconds and then starts quick blinking at 0.13 second intervals.
12. After ensuring the blinking of the VSC warning light for 2 seconds, turn the ignition switch OFF.
13. Remove the SST from terminals Ts and CG of DLC3.
Confirm Zero Point Calibration:
Drive the vehicle to confirm there are no re–occurring lights or DTCs.
