On my way home, my ABS light came on and the AFS OFF flashing light came on. Then about 20 minutes later it went off. Anyone know what the issue could be?
I did recently change the rear sway bar.

 

AFS and ABS have little in common. Any recent creek crossings / highwater?

 

Has the brake fluid ever been replaced?

 

No water crossings. Avoid them if I see them or go slow.

 

Changed maybe 2 years ago

 

You need to take it to an auto parts store and get the codes read, then we will know where to look. For now, inspect the left front and rear suspension by following wires to a sensor mounted on the body. The ride height sensor has an arm that connects to the suspension. The front one connects near the sway bar mount to lower arm. The rear to a bracket on the lower control arm. It's really tiny ball-joints to the sensor compared to the suspension parts it's keeping track of.

The sensors arm has a slot for adjusting the arms position in relation to suspension positions. Make sure they are there and connected. If possible, do this while the vehicle is at ride height vs wheels hanging down.

Left front is visible by turning the wheel. Rear might be visible through the wheel depending on the wheel.
