What you need is a scanner that does ABS and tell us what the code is.

J6 and J7 and M37 are the fuses associated with the ABS/TCS system. As far as I know, there is not a replaceable relay for the ABS system.

Hi,my scanner says c100a on abs mode.and dti mode po734
OK, so it's still seeing an issue with the left front. C100a

Have you checked the sensor wires to make sure that you don't have damage? Made sure the sensor connector that is behind the inner fender is securely connected? Cleaned the tone ring which is on the unit bearing? Made sure the actual sensor went in straight and is torqued correctly?

Follow the steps in the link Rhino gave you, the troubleshooting steps are excellent.

P0734 is a transmission issue, gear 4 ratio incorrect. This is a different issue and will not be lighting the TCS lamp.
