32. OPERATION OF ABS AND ABS/ASR ABS (ANTI-SKID BRAKE SYSTEM) When the truck is braked suddenly or braked on a slippery snow- covered road, etc., this system works to prevent the tires from locking and skidding. Accordingly, the truck is kept in a normal attitude and good steering performance is secured. ABS/ASR (Automatic Spin Regulator) In addition to the above functions of the ABS, this system has a function to prevent slipping of the drive wheels caused by exces- sive torque.
