Abs/advanced trac/airbag light on

[Tdavisss]

Did a pull last night and all the lights (abs , advanced trac , airbag , traction control etc ) came. Any thoughts on what it could be ? Replaced both rear wheel hubs like a month or two ago. Also have a U0415 Code.

I'm pretty sure you should have a code when scanned. I had the same lights on another of my cars and it was a wheel speed hub sensor . Good Luck

The code the came up was the “U0415” code. Is there a more in depth code i could get ?

I feel you should disconnect your two rear hub sensors which you said you had to reinstall in the new hubs you had replaced and OHM them, verify output voltage, wiring for chaffing ETC. If you have disconnected any other wiring some where else which works within one of those systems, check those. Good luck

I had same symptoms and same code. It was the drivers side rear hub. I'd start by looking there since you recently replaced them.

Where are the rear hub sensors located ? There were no sensors on the rear hubs on my car.

They are not on the hub itself, they are bolted behind the hub assembly. To replace the hub you should have disconnected the sensor wiring to prevent damage when you unbolted the LCA and upper bolt so you could swing the hub out to remove hub bolts

Yeah when i did the rear hubs i didn’t have to unbolt the LCA. I just simply took the caliper/rotor off then i was able to get to the four bolts holding the hub on.

Aside from the sensors, the common issue with traction/tire/abs/steering warning light weirdness - check the rear axle thrust washers, see here:

Also make sure the connector mentioned in this thread is fully seated and there's no issues with the connector or harness:

Just had my 2015 Mustang Gt Right rear wheel hub bearing assembly and right rear speed sensor replaced. The washer wasn't included in the replacement bearing assembly so is it really needed?
