stepdads just bought an ST24, nice motor...anyway - its got traction control, and its got me thinking

i know theres different types of traction control, mainly ones which have a BCV and use differentail braking to stop spinning, and you can get ones which split torque according to which wheel is spinning and which has most grip.

basiclly, i wanna know which the ST uses, and if anyone could point me in the dirrection of schematics and diagrams etc etc. if its the differential braking sort i recon itll be easy enough to do on my mk1...
