ABS Light on. Will AWD be affected?

96 Legacy L sedan with rear disc brakes. 4EAT transmission. I wasn't sure if the AWD operation would be compromised if my ABS light is on. I was thinking it wouldn't since ABS was an option on the "L" submodel.

I thought the 4EAT used the ABS sensors in the hubs to check for slip. If one of those is out, AWD may act odd.

Check that there's no crud in between the tone wheel and sensor. They can get rust/dirt/snow wedged up there that makes them act up.

A bad ABS sensor signal has been detected by the "touching the wires" method of reading the ABS flashes to get codes.

However, Dosen't the same AWD system get used on non-ABS equipped cars. I'm hoping the two systems aren't reliant on one another.

Found the answer to my question. There are 2 speed sensors supplying the TCU. Vehicle speed sensor #1 mounts to the transmission and monitors the rear axle. Vehicle speed sensor #2 is built into the combination meter. The ABS wheel sensors are not instrumental in the AWD function.

The ABS wheel sensors are not instrumental in the AWD function.

this is correct, for the 90s and early 00s,

except for the outback VDC.

 

not sure about the later years, 05+.
