2006 Ford Mustang with ABS light and TCS light. What do I do?

I recently got an 06 Mustang with an ABS light and TCS light on. I had it checked out just by a quick view. The guy does not believe my hub assembly or bearings are bad. I replaced the ABs sensor and it still did not seem to help. When I had it scanned the computer said it is the passenger rear ABS. I have no grinding, no noises, no issues driving, but I want to fix it properly. Does anyone have any ideas on what steps to take now?

If the sensor was replaced and the fault not sorted then the wiring is the next thing to look at

I agree with Timbo. But… Keep in mind that even with an ABS fault code you still have functioning brakes. As in years past, before ABS, the brake hydraulic system still functions without the ABS so sorting out the problem isn't an emergency concern. If the scan indicated the RR sensor and its been replaced the fault is likely in the wiring to that sensor. ABS failures don't often involve the same symptoms as a mechanical issues do because the only ABS component located at the wheel is the sensor. Every other ABS function is handled at the controller in the engine compartment.

If the traction control and ABS light are on at the same time, that points to the ABS control module being bad, as the traction control works off the ABS system.

I agree with Timbo and G-man as well. However, should the light still remain after repairing the wiring harness, do have a look at the Hydraulic Control Unit (HCU) and the ABS-Module itself by conducting a computerised pulse width test. I would consider this to be the last step in the diagnosis as it is particularly expensive.

I recommend taking your Mustang to the nearest Ford Dealer to be diagnosed. Our certified technicians will be able to advise you of the next steps to reach a resolution.
