These codes do indicate a calibration concern, did you follow the factory steps to do the recalibration?

Customer: replied 11 months ago.
Not sure what u mean by the factory steps? Please educate me on that

Have a look at the link below for the steps to run the calibration steps and see if this will help you get these codes to clear.

Ok yeah i did something similar but i guess i may not have followed it as listed here.
I made sure the gear is in P position, Got the ignition ON but the engine OFF
Went into the ABS/VSC/TRC
Clicked on Utility/test mode
Both Tyre light and Slip Indicator light were blinking ON and OFF
I waited for 10 secs and OFF the ignition
Started the engine ...
BUT the lights did not go away !
Not sure i got it right... please advise if i was supposed to do something else
