Well I finally replaced the lower ball joints and all 4 struts on my 97 legacy gt. Of course I had to remove the brake lines to install the struts. I also unbolted the abs sensors to prevent damage. After finishing the job and bleeding the brakes my abs light came on. I tried reading for codes and came up with nothing. No codes. I also reset the ecu and still nothing the light stays on. Any suggestions besides take it to a dealership?

The gap between the tone wheel and sensor may have changed, triggering a fault light.

ah yes...didn't think of that. I'll have to check that out as soon as it warms up

On first generation legacies. there is an ABS diagnostic LED under the passenger seat. Don't know if it's applicable to later models. Might help isolate the source.
