I believe its to controll the anti lock breaks. Reads all 4 sensors IIRC.

lol

so the unit does nothing unless im using the brakes? correct
it does not have the abilty to help control traction, like modern traction control systems?

It is NOT a traction control device. It is only for ABS. Also a note: Supras have a 3-channel system, there are 3 sensors. Unless you are talking about a JZA70, which does have a 4-channel setup.

i believe jdm wise it was introduced sometime in 87
have you check the hatch vin to see if it matches the firewall?

edit: correct information as follows:
all cars with 4esc stickers still only had 3 sensor abs, it wasn't until cars then got the 4abs sticker in 89 sometime that it was changed to 4 wheel

Hence, the name. Control the skid, not the traction. A skid is when the brakes are locked. You can not steer too well when the wheels are locked.

I spy a 79-81 Celica Supra in front.

Yes thats one of my MA45's.... the parts/ R&D car i swaped for a diff

I just looked through my Aus, Japan, Europe, and North American parts catalogs. Only the JZA70 had 4-channel ABS.

Obviously the other models still had 4-wheel ABS, just not 4-channel.
