No signal to the front left wheel bearing. Service vehicle light on, trac off light on, abs light on. I swapped the wheel bearings twice now and just put new rotors and pads all the way around. i am at a loss honestly. I dont have a clue what it could be? I originally thought it was a tranny code but it wasn't it pulled up the code for no signal to speed sensor which is in the hub assembly. Help

No wheel speed input will turn on all those lights. For those systems to work, requires the comp knowing the speed of ALL the wheels...

A bad sensor is a common problem but if you've change the sensor and there is no LF input then the problem is either a bad/broken/shorted wire, bad connecter or faulty EBCM (brk comp).

You could check the wires between the sensor & EBCM for continuity with an ohm meter, visually check the connectors for a loose fit. After that without the right tools in might be a good idea to take it in to have it checked..........
