Stability Control intervention at very low speed - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

smbstyle · 07-14-2016, 07:38 AM

At low speed, without traction control off, going around a corner at about 5 mph, the stability control will lose it's shit and start throwing out rear brake for no reason, with the stability sontrol light flashing like crazy. Then, the stability control light and ABS light will stay illuminated.

On track, as long as I do the pedal dance, there is no noticeable issue, however the ABS / TC light will stay illuminated every once in a while, with no change in drivability. If the ABS / stability control light come on first, I cannot get traction control off or do the pedal dance.

Any ideas where to start?

What mods do you have installed? First thing that comes to mind is wheel speed sensor.

I'd start by disconnecting the battery for a spell ....... then re-connect ....... to see if the system would right itself.

Is your wheel setup staggered or square?

Do you use the Torque app?

With Doug's incident and the newly blown diff, it could be anything. Have y'all replaced the diff already? Could be related to that.
